Safety Information
Before you use the SPS GPS receivers, make sure that you have read and understood all
safety requirements.
Regulations and safety
The Bluetooth module inside the SPSx50 Modular GPS receiver, the SPSx80 Smart GPS
antenna, and the ACU, TSC2, and TCU controllers is a radio-modem transmitter and
receiver.
Regulations regarding the use of the radio-modems vary greatly from country to
country. In some countries, the unit can be used without obtaining an end-user license.
Other countries require end-user licensing. For licensing information, consult your
local Trimble dealer.
Before operating an SPSx50 Modular GPS receiver or SPSx80 Smart GPS antenna,
determine if authorization or a license to operate the unit is required in your country. It
is the responsibility of the end user to obtain an operator’s permit or license for the
receiver for the location or country of use.
For FCC regulations, see Notices, page iii.
*****Query from RobMiller - SPSx50 and SPSx80 receivers also contain internal
transmit radios. Does this information apply to them as well? If not - more needs to be
added here.
Type approval
Type approval, or acceptance, covers technical parameters of the equipment related to
emissions that can cause interference. Type approval is granted to the manufacturer of
the transmission equipment, independent from the operation or licensing of the units.
Some countries have unique technical requirements for operation in particular
radiomodem frequency bands. To comply with those requirements, Trimble may have
modified your equipment to be granted Type approval. Unauthorized modification of
the units voids the Type approval, the warranty, and the operational license of the
equipment.
Exposure to radio frequency radiation
The radiated output power of the internal Bluetooth wireless radio is far below the
FCC radio frequency exposure limits.
Nevertheless, the wireless radio shall be used in such a manner that the Trimble
receiver is 2.0 cm or further from the human body. The internal wireless radio operates
within guidelines found in radio frequency safety standards and recommendations,
SPSx50 Modular GPS Receiver User Guide
Safety Information
which reflect the consensus of the scientific community. Trimble therefore believes the
internal wireless radio is safe for use by consumers. The level of energy emitted is far
less than the electromagnetic energy emitted by wireless devices such as mobile
phones. However, the use of wireless radios may be restricted in some situations or
environments, such as on aircraft. If you are unsure of restrictions, you are encouraged
to ask for authorization before turning on the wireless radio.
*****Query from RobMiller - SPSx50 and SPSx80 receivers also contain internal
transmit radios. Does this information apply to them as well? If not - more needs to be
added here.

Features and Functions
Use and care
The SPSx50 receiver is designed to withstand the rough treatment and tough
environment that typically occurs in construction applications. However, the receiver
is a high-precision electronic instrument and should be treated with reasonable care.
CAUTION – Operating or storing the receiver outside the specified temperature range can
damage it. For more information, see Appendix A, Specifications.
COCOM limits
The U.S. Department of Commerce requires that all exportable GPS products contain
performance limitations so that they cannot be used in a manner that could threaten
the security of the United States. The following limitations are implemented on the
SPSx50 receiver: Immediate access to satellite measurements and navigation results is
disabled when the receiver velocity is computed to be greater than 1000 knots, or its
altitude is computed to be above 18 000 meters. The receiver GPS subsystem resets
until the COCOM situation clears. As a result, all logging and stream configurations
stop until the GPS subsystem is cleared.

Battery performance
Battery safety
Battery charging and storage
Disposing of the rechargeable
Lithium-ion battery
Operating with the controller or
laptop computer
The SPSx50 GPS receiver uses an internal
rechargeable Lithium-ion battery.
The battery can be replaced only at an
Authorized Trimble Service Center.
The receiver can also be powered by an external
power source that is connected to the Lemo or
modem port.
The operational time provided by the internal
battery depends on the type of measurement
and operating conditions. Typically the internal
battery provides >15 hours operation as a base
station and >20 hours as a rover during
measurement operations using the internal
radio.

Batteries and Power
External power
The external power source is always used in preference to the internal batteries. When
there is no external power source connected, or if the external power supply fails, the
internal battery is automatically used. In this way the internal battery acts as an
uninterruptible power supply covering times of power failure. The internal battery will
only charge from an external power source which delivers more than 15 volts, for
example, an AC power adaptor.
During static measurement data logging, if no external power is supplied and the
internal battery is drained, the receiver will switch off. However, all collected data is
secure. If the receiver is operating as a base station when this happens, the receiver
will power down and stop transmitting corrections. When power is restored to the
receiver, it will resume operation in the same status that it was in when power was lost,
using the same settings as before the shut down.
Battery performance
Batteries perform best when they are not used in extreme temperature conditions. The
receiver is designed to be used in operating temperatures of –40 °C to +65 °C (–40 °F
to +149 °F). However, extremely cold temperatures of less than 0 °C (32 °F) can cause
the battery life to quickly drop. Do not expose the receiver to storage temperatures
outside the range –40 °C to +70 °C (–40 °F to +158 °F).
To protect the battery from deep discharge (5 V or less), the receiver is designed to
switch power sources or cease drawing power when the battery pack discharges to
5.9 V. A battery that has reached the deep discharge level cannot be recharged and
must be replaced. The following recommendations provide optimal performance and
extend the life of your batteries:
•
Fully charge all new batteries before use.
•
Do not allow the batteries to discharge below 5 V.
•
Keep all batteries on continuous charge when not in use. Batteries may be kept
on charge indefinitely without damage to the receiver or batteries.
Battery safety
The receiver is powered by a rechargable Lithium-ion battery. Charge and use the
battery only in strict accordance with the instructions below.
28
WARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery
can cause an explosion or fire, and can result in personal injury and/or property damage.
To prevent injury or damage:
– Do not use or charge the battery if it appears to be damaged. Signs of damage include,
but are not limited to, discoloration, warping, and leaking battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight.
– Do not immerse the battery in water.
SPSx50 Modular GPS Receiver User Guide
Batteries and Power
– Do not use or store the battery inside a vehicle during hot weather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.
WARNING – Avoid contact with the rechargeable Lithium-ion battery if it appears to be
leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or
property damage.
To prevent injury or damage:
– If the battery leaks, avoid contact with the battery fluid.
– If battery fluid gets into your eyes, immediately rinse your eyes with clean water and
seek medical attention. Do not rub your eyes!
– If battery fluid gets onto your skin or clothing, immediately use clean water to wash off
the battery fluid.
Battery charging and storage
All battery types discharge over time when they are not being used. Batteries also
discharge faster in colder temperatures. If a Lithium-ion battery is to be stored for long
periods of time, make sure it is fully charged before storing and re-charged at least
every three months.
The SPSx50 receiver has an integrated Lithium-ion battery and the charging circuitry
is integrated into the receiver. The battery is charged when it is connected to a power
source delivering greater than 15 V. The receiver is supplied with a mains power supply
unit that recharges the battery inside the receiver when it is connected through the
adapter to the modem port or the Lemo port. When you use the receiver on large
projects, from a permanent or semi-permanent base station location in a site cabin,
Trimble recommends that you use this power supply at all times to keep the internal
battery charged. This provides an uninterrupted power supply during mains power
outages and will keep the site operational for more than 10 hours after a power failure.
WARNING – Charge and use the rechargeable Lithium-ion battery only in strict
accordance with the instructions. Charging or using the battery in unauthorized
equipment can cause an explosion or fire, and can result in personal injury and/or
equipment damage.
To prevent injury or damage:
– Do not charge or use the battery if it appears to be damaged or leaking.
– Charge the Lithium-ion battery only with a Trimble product that is specified to charge it.
Be sure to follow all instructions that are provided with the battery charger.
– Discontinue charging a battery that gives off extreme heat or a burning odor.
– Use the battery only in Trimble equipment that is specified to use it.
– Use the battery only for its intended use and according to the instructions in the product
documentation.
Charging the Lithium-ion battery
The rechargeable Lithium-ion battery is supplied partially charged. Charge the battery
completely before using it for the first time. If the battery has been stored for longer
than three months, charge it before use.
SPSx50 Modular GPS Receiver User Guide
29
3
Batteries and Power
The internal battery charges fully in 8 hours when connected to a suitable power
source.
Disposing of the rechargeable Lithium-ion battery
The integrated Lithium-ion battery should be removed only at an authorized service
center. If the battery is removed at an unauthorized service center, the remaining
warranty on the product will be void.
After you remove the Lithium-ion battery, discharge it fully before disposing of it.
When disposing of the battery, be sure to do so in an environmentally sensitive
manner. Adhere to any local and national regulations concerning battery disposal or
recycling.
Operating with the controller or laptop computer
During operation, the controller will typically be connected to the receiver using the
Bluetooth cable free connection. Where a serial connection is used, the receiver
delivers no power through its communications ports to the controller, which must
have its own source of power in order to operate.

Setup Guidelines
Base station operation guidelines
For all GPS Real-Time Kinematic (RTK) operations, you require both a base station and
a rover.
RTK operation provides centimeter-level accuracy by eliminating errors that are
present in the GPS system. A receiver placed at a known position (the base station)
tracks the satellites that are being tracked by the rover receiver, at the same time that
the rover is tracking them. Errors in the GPS system are monitored at the fixed (and
known) base station, and a series of position corrections are computed. The
corrections are sent through a radio link to the rover receiver, where they are used to
correct the real time positions of the rover.
This section discusses the base station component and its role in providing an RTK
solution.
Base station components
The base station has the following components:
•
•
•
•
GPS receiver
GPS antenna
base station radio
power supply
GPS receiver and GPS antenna
The base station GPS receiver can be one of following types:
•
A Smart GPS antenna, such as the SPSx80 receiver, incorporates a GPS receiver,
GPS antenna, power supply, and base station radio into a single compact unit. A
Smart GPS antenna can be rapidly set up on a tripod, fixed height tripod, or
T-Bar anywhere that is convenient on the jobsite.
•
A modular GPS receiver, such as the SPSx50 receiver, incorporates a GPS
receiver, power supply, and base station radio in a single unit. The GPS antenna
and, optionally, the base station radio antenna is separate from the receiver.
Because the GPS antenna is separate, you can use the following optimized
components:
– a geodetic antenna with large ground plane, to eliminate multipath (the
major source of GPS errors) at the base station
– a high gain or directional radio antenna, to increase broadcast range and to
provide maximum coverage
You can also place a modular GPS receiver in an easily accessible and secure
location, safe from theft and the weather, while the antennas are placed high on
a tower or building, clear of obstructions and able to deliver maximum
performance.
You can use either type of receiver in a permanent, semi-permanent, or daily quick
setup configuration. If semi-permanent or permanent operation is required, however,
the modular receiver delivers significant advantages.

SPSx50 Modular GPS Receiver User Guide
4
Setup Guidelines
Base station setup guidelines
For good performance, observe the following base station setup guidelines:
•
Place the GPS receiver in a location on the jobsite where equal range in all
directions provides full coverage of the site. This is more important on larger
jobsites, where the broadcast range of the base station radio may limit the
operations of the GPS system.
•
Place the GPS antenna in a location that has a clear line of sight to the sky in all
directions. Do not place the GPS antenna near vertical obstructions such as
buildings, deep cuttings, site vehicles, towers, or tree canopy.
•
Place the radio antenna as high as practical. This minimizes multipath from the
surrounding area, and enables the radio to broadcast to the maximum distance.
Note – The radio antenna must have a clear line of sight to the sky at all times during
operation.
•
Choose the most appropriate radio antenna for the size and footprint of the site.
The higher the gain on the antenna, the longer the range. If there is more focus
on the transmission signal, there is a reduced coverage area. A 3 db or 5 db gain
antenna provides a mix of good range and reasonable directional coverage.
•
Make sure that the GPS receiver does not lose power. The GPS receiver has an
integrated battery, which has to be charged. To operate for the full day without
loss of power at the base station, provide external power. Sources of external
power include:
–
AC power
–
12 V car or truck battery
–
Trimble custom external battery pack
–
Generator power
–
Solar panel
When you use an external power supply, the integrated battery provides a
backup power supply, enabling you to maintain continuous operation through
power outages. When the GPS receiver is connected to a power source greater
than 15 V, the integrated battery is continuously charged from the connected
power source. This helps to ensure that the battery stays charged.
•
Do not locate a GPS receiver, GPS antenna, or radio antenna within 400 meters
(about 1312 feet) of:
–
a powerful radar, television, or cellular communications tower
–
another transmitter
–
another GPS antenna
SPSx50 Modular GPS Receiver User Guide

4
Setup Guidelines
Cellular phone towers can interfere with the base station radio broadcast and
can stop corrections from reaching the rover receiver. High-power signals from a
nearby radio or radar transmitter can overwhelm the receiver circuits. This does
not harm the receiver, but can prevent the receiver electronics from functioning
correctly.
Low-power transmitters, such as those in cellular phones and two-way radios,
do not interfere with receiver operations.
•
Do not set up the base station directly beneath or close to overhead power lines
or electrical generation facilities. The electromagnetic fields associated with
these utilities can interfere with GPS receiver operation. Other sources of
electromagnetic interference include:
–
Gasoline engines (spark plugs)
–
Televisions and computer monitors
–
Alternators and generators
–
Electric motors
–
Equipment with DC-to-AC converters
–
Fluorescent lights
–
Switching power supplies
•
Place the GPS receivers in a protected and secure location. If the base station is
in the center of a jobsite where heavy machinery is operating, place flags around
the base station to warn operators of its existence.
•
If you place the SPSx50 Modular GPS receiver or SPS770 GPS receiver in a lock
box on the jobsite to protect the receiver from theft or from the weather, shield
the lock box from direct sunlight and provide ventilation for the receiver
through an inlet and extractor fan. A receiver that has a broadcast radio
generates significant heat. Do not allow the temperature in the box to exceed
65 ºC (149 ºF).
If working in a cold climate, you may need to provide heat to the receiver. Do not
operate the receiver below –40 ºC (–40 ºF).
•
34
Trimble recommends that, wherever possible, you keep GPS receiver equipment
dry. The receivers are designed to withstand wet weather, but keeping them dry
prolongs their life and reduces the effects of corrosion on ports and connectors.
If the equipment gets wet, dry the equipment with a clean dry cloth, and leave
the equipment open to the air to dry. Do not lock wet equipment in a transport
case for prolonged periods. Avoid exposing the GPS receiver to corrosive liquids
and salt water wherever possible.
SPSx50 Modular GPS Receiver User Guide
Setup Guidelines
•
Trimble recommends that you install lightning protection equipment at
permanent base station locations. Equipment should include a gas capsule
lightning protector in the GPS and radio antenna feed line and appropriate
safety grounding. A static dissipater near the antennas can reduce the likelihood
of a direct lightning strike. Also protect any communications and power lines at
building entry points. For more information, contact your local Trimble dealer,
or go to the Huber and Suhner website (www.hubersuhnerinc.com).
•
Trimble recommends that you use surge protection equipment on all
permanently installed equipment.
Permanent installation antenna cabling for the SPSx50 Modular GPS
receiver and SPS770 GPS receiver
Many permanent base station installations have unique cabling requirements.
Depending on the available infrastructure, you may need to mount the antenna a
considerable distance from the receiver.
The SPSx50 and SPS770 can withstand a loss of 12 dB between the GPS antenna and
the receiver. The degree of loss in a coaxial cable depends on the frequency of the
signal passing through it. Table 4.1 lists some common cable types and the maximum
length you can use before an inline amplifier for GPS frequencies is required.

Rover receiver operation guidelines
The second part of the RTK GPS system is the rover receiver.
The rover receiver is mounted on a pole, vehicle, marine vessel, or in a backpack, and is
moved between the points that require measurement or stakeout. The rover receiver is
connected to a base station or to a source of RTK corrections such as a Virtual
SPSx50 Modular GPS Receiver User Guide

Setup Guidelines
Reference Station (VRS™) system. The connection is provided by an integrated radio, a
cellular modem in the controller, or through an external cellular phone that is
connected to the receiver either by Bluetooth wireless technogy or by means of a cable.
The correction stream for some other positioning solutions, such as SBAS
(WAAS/EGNOS, MSAS) and the OmniSTAR XP or HP service1, is broadcast through
geostationary satellites, and detected by the GPS antenna itself. No integrated radio or
base station is required.
Rover receiver components
The rover receiver has the following components:
•
GPS receiver
•
GPS antenna
•
Optional integrated radio receiver and antenna for RTK operations
•
Optional items for the different mounting options (see below)
In most rover applications, the receiver operates entirely from its own integrated
battery unit. On a vehicle or on a marine vessel, however, an external power supply can
be used. Use an external power supply if one is provided. The internal battery then acts
as a uninterruptible power supply, covering any power outages.
Choose a rover receiver according to the application and the use case:
1.
A Smart GPS antenna, such as the SPSx80 GPS receiver, incorporates the GPS
receiver, GPS antenna, power supply, and receive radio into a single compact
unit. A Smart GPS antenna can be rapidly set up on a pole, vehicle, or backpack.
This makes it easy to carry when you are measuring around the jobsite.
2.
A Modular GPS receiver, such as the SPSx50 GPS receiver, incorporates the GPS
receiver, receive radio, and power supply into a single unit. The GPS antenna
and, optionally, the receive radio antenna, is separate from the receiver. When
you use a modular receiver as a rover, you can use optimized components
placed in the best locations for your application. For example:
–
A small, lightweight rover antenna can be mounted on a pole or backpack;
placed in a high, inaccessible location on a marine vessel mast or cabin; or
placed on a site vehicle roof or truck bed.
–
A rubber duck radio antenna, or an external radio antenna, can be
mounted on a vehicle or vessel roof to provide maximum coverage.
A Modular GPS receiver can be placed in a location that is both easily accessible
and safe from theft and the weather. The antennas can be placed high on a
vehicle or vessel roof, clear of obstructions and able to deliver maximum
performance.

OmniSTAR is only available with the SPSx50 Modular GPS receiver.

SPSx50 Modular GPS Receiver User Guide
Setup Guidelines
Rover receiver setup guidelines
For good rover operation, observe the following setup guidelines:
•
Place the GPS antenna in a location that has a clear line of sight to the sky in all
directions. Do not place the antenna near vertical obstructions such as
buildings, deep cuttings, site vehicles, towers, or tree canopy. GPS rovers and the
base station receive the same satellite signals from the same satellites: if you
obscure the signals at times, the system will be unable to provide RTK Fixed
positions.
•
Place the GPS and radio antennas as high as possible to minimize multipath
from the surrounding area. The receiver must have a clear line of sight to the sky
at all times during operation.
•
GPS satellites are constantly moving. Because you cannot measure at a specific
location now does not mean that you will not be able to measure there later,
when satellite coverage or location improves. Use GPS planning software to
identify the daily best and worst satellite coverage times for your location, and
then choose measurement times that coincide with optimal GPS performance.
This is especially important when operating in the worst GPS locations.
•
The SPS850 Extreme and SPS880 Extreme GPS receivers have the ability to track
the GPS modernization signals L2C and L5, and the GLONASS satellite
constellation. These signals help you to get positions at the worst times of the
day and in the worst GPS locations, but do not guarantee that you will.
•
To get a fixed position solution with centimeter accuracy, initialize the rover
receiver. For initialization to take place, the receiver must track at least five
satellites that the base station is also tracking.
•
To maintain a fixed position solution, the rover must continuously track at least
four satellites that the base station is also tracking. The radio link between base
and rover receivers must also be maintained.
•
Loss of the satellite signals or loss of the radio link results in a loss of centimeter
position accuracy. From Fixed, the receiver changes to Float or Autonomous
mode:
•
–
In Float mode, the rover has connection to the base station through a radio,
but has not yet initialized.
–
In Autonomous mode, the rover has lost radio contact with the base
station receiver, and is working by itself with the available GPS signals.
On a vehicle or marine vessel, place the GPS antenna in a location as free from
shock and vibration as possible. For the modular receivers, a single magnetic
mount is normally sufficient to hold the antenna in a suitable location, whereas
for the larger smart antenna, a triple magnetic mount is normally
recommended. Alternatively, a 5/8 thread bolt in a suitable location on the roof
bars, or a door mounted pole bracket is a good option.
SPSx50 Modular GPS Receiver User Guide

Setup Guidelines
•
To mount the modular receiver on a pole use the pole mounting brackets (2)
and a second tripod clip (P/N 571 204 300) as shown below.
Rob to provide graphic.
Figure 4.1
Rod mount for modular receiver
To mount the modular receiver on a marine vessel use the receiver bracket
(P/N 56830-00). The receiver bracket allows two receivers to be mounted
together for marine moving base and heading applications (see chapter XXX
Page XXX)
38
•
Make sure the rover receiver does not lose power. The rover receivers are
typically powered from their internal batteries all day. The batteries in the
SPSx80 receiver can be changed when flat. The battery in the SPSx50 receiver
cannot be changed, but it last longer than a day (see Chapter 10, Specifications).
If you do not use the rover receiver very often, ensure that it is charged at least
every three months. For vehicle operation or marine vessel operation, Trimble
recommends that you use an external power source so that the internal battery
can be saved for times when the receiver is being used off the vehicle or vessel.
•
Avoid locating the receiver or antenna within 400 meters of powerful radar,
television, cellular communications tower, or other transmitters or GPS
antennas. Low-power transmitters, such as those in cell phones and two-way
radios, normally do not interfere with receiver operations. Cell towers can
interfere with the radio and can interfere with GPS signals entering the receiver.
High-power signals from a nearby radio or radar transmitter can overwhelm the
receiver circuits. This does not harm the receiver, but it can prevent the receiver
electronics from functioning correctly.
•
Do not use the rover receiver directly beneath or close to overhead power lines
or electrical generation facilities. The electromagnetic fields associated with
these utilities can interfere with GPS receiver operation. Other sources of
electromagnetic interference include:
–
Gasoline engines (spark plugs)
–
Televisions and computer monitors

•
Trimble recommends that wherever possible all GPS receiver equipment is
protected from rain or water ingress. The receivers are designed to withstand all
wet weather conditions, however keeping the receivers dry prolongs the life of
the equipment and reduces the effects of corrosion on ports and connectors. If
the equipment does get wet, dry the equipment with a dry cloth, and leave the
equipment open to the air to dry. Do not lock wet equipment in a transport case
for prolonged periods. Avoid exposing the GPS receiver to corrosive liquids and
salt water wherever possible.
•
When using the rover receiver in open spaces, Trimble recommends that you
stop work during electrical storms where the risk of lightning strike is high.
•
Where cables are involved, Trimble recommends that you use cable ties to
secure the cables to the rod or other equipment to avoid inadvertent snagging
while moving about the jobsite. Be careful not to kink, twist, or unnecessarily
extend cables, and avoid trapping them in car doors or windows. Damage to
cables can reduce the performance of GPS equipment.
Internal radio setup for rover operations
The internal radio of the SPS GPS receiver is delivered with the TX radio frequencies
preprogrammed into the receiver. To add more RX radio frequencies, use the WinFlash
utility (see Appendix C, Adding Internal Radio Frequencies).
Once the radio frequencies are configured, use the SCS900 software to select channel
frequencies during base station or rover setup operations.
For more information, refer to the the WinFlash Help, or the SCS900 User Guide.
External radio setup
To use an external radio with the SPS770 GPS receiver, you need an external power
source for the radio.
To set up the receiver using an external radio:
1.
Connect one end of the yellow GPS antenna cable to the yellow TNC port on the
receiver.
2.
Connect the other end of the GPS antenna cable to a Zephyr or Zephyr Geodetic
antenna.
3.
Connect the external radio to Port 3 on the receiver.

Connecting an external radio
Connect an external power source to Port 2 on the receiver.
Note – External rover radios must have their own power source because the internal
Lithium-Ion batteries do not supply enough voltage. Alternatively, supply external power to
port 2 of the receiver, and enable power out on port 3.
Base radios must have their own power source because of their high power consumption.
Cellular modem and external radio
Instead of the internal radio, you can use a cellular modem or an external radio as your
data communications link.
To connect a cellular modem to an SPSx80 Smart GPS antenna, you need the following:
•
SPSx80 Smart GPS antenna.
•
One of the following:
–
TSC2 controller with CompactFlash card cellular modem, for example, a
Audiovox modem card
–
Cellular modem or a cellphone that can transmit data
•
Serial (cellphone to DB9) cable (supplied with the cellular modem or phone).
•
Port 2 of the SPSx80 supports full RS-232 protocol, and should function properly
with most cellular phone cables. Some cellular units may require custom
cabling.
Alternatively, the receiver also supports a cable-free Bluetooth connection with
Bluetooth enabled cell phones.
For more information on using a cellular modem as a data link, refer to the SCS900 User

•
430–450 MHz (Tx/Rx, Rx only, or Tx only)
•
450–470 MHz (Tx/Rx, Rx only, or Tx only)
•
900 MHz (Tx/Rx, Rx only, or Tx only)
Note – “Tx” indicates that the radio transmits corrections. “Rx” indicates that the receiver
receives corrections. “Tx/Rx” indicates that the radio both transmits and receives
corrections.
If the SPSx50 receiver does not have an internal transmit radio, or you want to connect
to higher power or to a secondary external transmit radio or cellular phone, use the
26-pin port, the Lemo port, or Bluetooth wireless technology.
The SPSx50 receiver supports the following Trimble base radios:
•
TRIMMARK 3
•
Trimble SNB900
•
Trimble PDL450
•
Trimble HPB450
The SPSx50 receiver also supports third-party transparent radios and third-party

When used with an SPSx50 GPS receiver, most external radios require an external
power source. Only the Trimble SNB900 radio-modem has an internal battery and does
not require external power.
Configure the external radio separately, using either the configuration program for the
external radio or the radio display and keypad.
To configure the SPSx50 for RTK operation, follow the base setup procedure to set the
following parameters:
•

Common ways to set up a base station
The following sections describe how to set up a base station in different ways
depending on the application, coverage area, degree of permanence versus mobility,
and available infrastructure.
Setting up a base station for permanent or semi-permanent installation
For construction applications, where machine and site positioning operations using
GPS will be carried out over a long time (weeks, months, or years), ensure that you
carefully choose the base station location.
The degree of permanence of the setup increases with the expected duration of
operational requirements. The more assets that use the base station as a source of
corrections, increases the cost of any base station downtime, and increases the
requirements for a permanent base station setup. Providing a semi-permanent or
permanent setup can also reduce potential sources of error over time caused by
repeated daily setup and the potential to put the GPS antenna in the wrong place (that
is, not at the original location).
On the largest and longest operational jobsites, the permanent or semi-permanent
installation is the most common solution. In these cases it is most common to find the
SPSx50 Modular GPS receiver or the SPS770 Modular GPS receiver used as the base
station. In these installations, the GPS receiver is located typically in a site office or
trailer where it is easy to access to check or configure, and where it is secure from theft

and the weather. The GPS and radio antennas are normally mounted on a permanent
structure on the roof of the building, where they are high and clear from obstructions
and where the radio antenna can provide the maximum range of operation.
The GPS antenna used is most commonly the Zephyr Geodetic – Model 2 antenna,
which has a large ground plane that eliminates multipath, providing the best GPS
performance at the base location. The antennas are connected to the receiver by high
quality RF cables.
The receiver is connected to a permanent power supply (mains or generator power).
The internal battery of the receiver is always being charged, and acts as an
uninterruptible power supply if there is a power outage. In some cases, the receiver
may also be connected by an Ethernet cable to the Internet, so that it can be
monitored and configured from a remote location, and warn an administrator by
e-mail or text message if there is a change to the configuration. In these situations, the
receiver can transmit GPS RTK corrections to a remote radio or receiver over the
Internet for rebroadcast requirements without using repeaters.

Setting up a Base Station for Daily Site Use: T-Bar
For construction applications where a daily setup and takedown of equipment is
required for security reasons, Trimble recommends that you use a T-Bar setup.
The T-Bar consists of a post mounted in concrete (so it cannot move), which has a
solid metal Bar T piece mounted to it to provide lateral separation between the GPS
antenna and radio antenna. The T piece of the T-Bar will have vertical rods at either
end, terminating in a 5/8 thread to which the antennas can be mounted. Trimble
48
SPSx50 Modular GPS Receiver User Guide
5
Setting up the Receiver
recommends that each end is clearly marked GPS and Radio respectively, to ensure
that at each daily setup the GPS and Radio antennas are mounted at the same location.
Switching antennas by mistake introduces a position error in all resulting
measurements. The equipment required to fabricate a T-Bar can be purchased in any
reputable hardware store. Take care to ensure that the T-Bar cannot rotate after
construction. Rotation of the T-Bar can introduce a position error into all subsequent
measurements.
On the upright post, either mount a bracket to which the GPS receiver can be
mounted, or place a lock box with ventilation on the post, in which the GPS receiver
itself can be secured.
Each day, mount the GPS antenna on the GPS end of the T-Bar and the radio antenna
on the Radio end of the T-Bar. Connect the Radio and GPS Antenna to the receiver
using the appropriate cables. In these scenarios, the receiver will operate from its own
integrated battery or from an external 12 V battery through use of the 12 V crocodile
clips cable provided with the receiver. If AC power is available, this can be used,
however the heat generated by the charging process and the radio transmitter
increases the need for good ventilation around the receiver to dissipate the heat.
In these scenarios an SPSx80 smart GPS antenna is also often used, in which case the
receiver only needs to be mounted on the T-Bar and optionally connected to an
external battery or radio unit.
The benefit of the T-Bar setup is that it is easy to ensure that the base station is set up
daily in the exact same location each day in terms of position and height, that will
eliminate the errors typically associated with daily setup on a tripod (wrong antenna
heights, not setup over the point, setup in the wrong location etc.)

Setting up a Mobile Base Station: Tripod and Fixed Height Tripod
For construction applications where you are repeatedly moving between jobsites, or
you are visiting a jobsite for the first time before a T-bar or similar setup can be
established, Trimble recommends that you use either a tripod and tribrach setup or a
fixed height tripod.
The fixed height tripod is quicker and easier to setup over a control point. In these
situations, you need to take great care to ensure that the GPS antenna is set up
accurately over the control point, and that the GPS antenna height is measured
accurately, in the right way (vertical or slope height) to the right location on the
antenna (base of antenna or to a specified location on the antenna). It is also more
important for operators using these types of setup to check in, at one or more known
locations, on starting the rover receiver to check for possible position or height errors
before starting work. Checking in at a known location is good practice and can avoid
costly errors caused by a bad setup.
The tripod and fixed height tripod method, typically does not give a significant height
clearance above the ground, and can result in reduced range of operation caused by
radio limitations.

Fixed Height Tripod Setup
Using a fixed height tripod, the setup is similar to that of the tripod setup, however the
setup is simplified by the central leg of the tripod, that is placed directly on the control
point. Provided the central leg is leveled accurately, the fixed height tripod is quick and
easy to set up, and provides an easy and accurate means of measuring the true
antenna height.

attached to the roof bars.
–
For the SPSx80, mount the receiver to the roof of the vehicle using either a
triple magnetic mount or a 5/8 thread bolt attached to the roof bars.
2.
For the SPSx50 or SPS770, run the GPS antenna cable for the receiver into the
vehicle either through a rubber grommet in the roof, or through the passenger
door window, which needs to be left slightly open during operation.
3.
For the SPSx50 or SPS770, place and secure the GPS receiver in a convenient
location in the vehicle.
The GPS receiver can be controlled via the controller connected using Bluetooth
wireless technology (cable free) (SPSx50 or SPSx80) or a cable connected to a
port on the receiver (SPS770).
SPSx50 Modular GPS Receiver User Guide
53
5
Setting up the Receiver
The receiver needs to be accessed only to turn it on at the start of each
measurement session. It may be more convenient if the SPSx50 is placed in a
location where the vehicle operator can see the keypad and display, to monitor
receiver status and to configure settings as required. Most receiver capability
can be controlled using the SCS900 controller software.
4.
Attach the suction cup to either the front windscreen, dashboard, or other
convenient location in the vehicle making sure that it does not obstruct the
drivers view.
5.
Attach the RAM extension arm to the suction cup, and the controller bracket to
the RAM extension arm.
6.
Lock the controller into the controller bracket, and adjust the bracket until the
controller is in the most convenient location. Make sure that the controller does
not restrict visibility through the front windscreen during vehicle use.

Setting up a rover receiver on a belt or in a backpack
The receiver can be work on a belt or carried in a backpack to eliminate weight from
the pole as needed. When you wear the receiver on a belt, ensure that the display is
always visible so that you can easily check the status of the receiver. If you carry the
receiver in a backpack, you should use an external radio antenna mount to allow for
optimal radio signal reception. If you use a low gain antenna mounted directly on the
receiver in a backpack, it may affect the radio signal reception thereby reducing the
likelihood of obtaining an RTK Fixed solution.

Setting up the Receiver
Setting up a pair of SPSx50 GPS receivers to provide heading
The SPS550H receiver is permanently in Heading mode and, when combined with a
suitable Trimble receiver, provides GPS heading. Other SPSx50 GPS receivers can be
used for heading only if they can operate in Heading mode (see Configuring the
receiver pair, page 64).
The SPS550H is a dual-frequency GPS receiver with a dual-frequency antenna, but it
does not operate as a stand-alone DGPS receiver. To compute a true north heading and
to be capable of positioning, the receiver requires an output message from another
SPSx50 receiver. To determine the precise vector between two moving objects, pair the
SPS550H heading add-on with any one of the following SPSx50 receivers:
•
SPS550
•
SPS750 Max
•
SPS850
Connect the antenna on the SPS550H to the other SPSx50 receiver to determine the
precise GPS heading between the two antennas. The SPS550H GPS receiver displays
the heading on the two-line display, and outputs the heading data in NMEA or binary
format.
Tip – To create a single, compact GPS position and heading unit, use the mounting frame
provided to stack the SPS550H GPS receiver on top of another SPSx50 GPS receiver. See
below. Use the Marine Heading Cable (P/N 57169) provided.
The Moving Baseline RTK positioning technique
In most RTK applications, the reference receiver remains stationary at a known
location and the rover receiver can move. However, Moving Baseline RTK is an RTK
positioning technique in which both reference and rover receivers can move about.
Moving Baseline RTK is useful for GPS applications that require vessel orientation.

Setting up the Receiver
With Moving Baseline RTK, the reference receiver broadcasts Compact Measurement
Record (CMR) data every epoch, while the rover receiver performs a synchronized
baseline solution at 10 Hz. The resultant baseline solution has centimeter-level
accuracy. To increase the accuracy of the absolute location of the two antennas, the
Moving Reference receiver can use differential corrections from a static source, such as
a shore-based reference station.
Mounting a pair of SPSx50 GPS receivers
To obtain a position and heading solution, you need to connect two SPSx50 receivers
to make one compact unit. A mounting bracket and interconnecting cable is supplied
with the SPS550H receiver. Set up the receivers, antennas, and cables as shown in
Figure 5.2.

15. Insert the first bolt. Attach the flat washer, the spring washer, and finally the nut
and then tighten firmly. Secure all eight bolts in this way..
16. Attach one connector from the Marine Heading Cable (P/N 57169) to the 26-pin
connector on the rear of the SPS550H GPS receiver. Attach the other connector
from the cable to the 26-pin connector on the rear of the SPSx50 receiver. The
cable can be connected either way around.
The cable connects the two GPS receivers so that the Heading solution is
available. The DC power lead on the cable is used to supply power to both
receivers in the stack. The two DB9 female connectors on the cable access serial
port 2 on each receiver.
Installing the receiver
Select a location at which all of the following conditions are met:
•
the receiver is not exposed to temperature extremes
SPSx50 Modular GPS Receiver User Guide
63
5
Setting up the Receiver
•
the receiver is not exposed to moisture extremes (such as rain, snow, water
blasters, or wash systems)
•
the receiver is protected from mechanical damage
•
you can connect and disconnect cables without placing undue stress on them
Mounting the antennas
It is critical that you install each antenna at the correct location. Poor or incorrect
placement can influence accuracy and reliability.
Ideally, mount the two antennas as far apart as possible and at about the same height
on the structure. Mount the antennas fore and aft along the vessel centerline or on a
line that is at a known orientation to the centerline. Always mount an antenna at a
location that ensures a good view of the sky.
Follow these guidelines to select the antenna location:
•
Choose an area with a clear view of the sky. The antenna must be above any
metallic objects.
•
Do not mount the antenna close to stays, electrical cables, metal masts, or other
antennas.
•
Do not mount the antenna near a transmitting antenna, a radar array, or near
satellite communication equipment.
•
Avoid areas with high vibration, excessive heat, electrical interference, and
strong magnetic fields.
Use a 5/8" stainless steel bolt to mount each of the antennas. There is a threaded bolt
hole in the base of the antenna.
Configuring the receiver pair
One of the receivers must be nominated as a Heading unit. The other receiver is
nominated as a Moving Base unit. For this configuration to work, you must use the
Marine heading cable (P/N 57169).
To set up the Heading unit:
1.
From the Home screen press . The Mode screen appears.
2.
Select Heading mode. The SPSx50 display shows two extra settings for heading:
–
64
Heading Adjustment. Enter a positive value in decimal degrees. The value is
applied to the raw heading value before it is output in the NMEA HDT
message or displayed on the front panel of the receiver. This value is used
when the two antennas are not mounted parallel to the vessel axis.
SPSx50 Modular GPS Receiver User Guide
5
Setting up the Receiver
–
Minimum Heading Solution. Enter the minimum requirement for the GPS
solution that will provide the heading value. The default of RTK Fixed
provides the highest precision, but in conditions of extreme multipath or
obstruction, an RTK Fixed solution may not be continuously available. In
such conditions, select RTK Float if a lower precision is acceptable.
To set up the Moving Base unit:
1.
From the Home screen press . The Mode screen appears.
2.
Select Moving Base mode.
Interfacing using the NMEA protocol
The SPS550H GPS receiver can output messages such as NMEA HDT for heading, and
NMEA GGA for position. The SPS550H always reports the solution status of the
moving baseline solution that is being used to compute the heading. For example,
Modem (serial port 2) on SPS750, which is typically RTK Fixed Integer. However, if the
external computer must know the exact quality of the position, you can use the NMEA
output from the base receiver. The base receiver reports the solution status of the
position, for example, Fixed Integer, Floating, orDGPS.

Configuring Ethernet Settings
Configuring the SPSx50 Receiver
Using a Web Browser
You can configure the SPS GPS receiver family in
a variety of ways. This appendix describes the
different configuration methods, and explains
when and why each method is used.
The SCS900 Site Controller software is likely to be
your main tool to set up and operate the receiver
on a daily basis. For more information, refer to
the Trimble SCS900 Site Controller Software
Getting Started Guide or the Trimble SCS900 Site
Controller Software Office Guide.
The external software detailed in this appendix is
primarily used to update the receiver firmware
and to configure upgrades or radio channels. All
necessary field configurations are handled
through the SCS900 software running on a
TSC2™ or TCU controller.

Configuring the Receiver Settings
Using the SCS900 Site Controller software to configure the
base station, rover, and the radios
As a total system solution for construction applications, the SPS GPS receivers are
operated by a TSCe™, ACU, TCU, or TSC2 controller running the SCS900 Site
Controller software. The SCS900 system provides the tools to configure and start the
GPS receiver in the modes used by the SCS900 system: Base Station, RTK Rover,
Location RTK Rover, OmniSTAR Rover, and DGPS Rover using SBAS (WAAS/EGNOS
and MSAS). The SCS900 software provide wizards to help you through the process and,
where possible, assigns suitable default operational parameters to the system. This
eliminates the need for an operator to know how to configure the receiver with the
right settings.
The SCS900 system takes care of operating the receiver with both internal and external
radios, cellular communications components (modems and cellphones), and use of the
Bluetooth wireless technology. The software also takes care of scanning
communication ports to identify connected devices, and offers selection options
wherever necessary often with pictures to facilitate the correct component selection at
times when it cannot automatically identify the connected component, for example,
GPS antennas.
Press Ctrl+M to open this screen
The SCS900 Sky Plot screen
The SCS900 system allows you to specify operational tolerances, which have to be
achieved for measurements to be accepted. When outside of these tolerances, the
SCS900 system warns you through on-screen messages or indications, and the non
automatic acceptance of recorded positions. To set operational tolerances, go to the
the Settings menu in the SCS900 software.
Configuring the receiver to log data for postprocessing
The SPS GPS receivers do not come equipped with the Data Logging option. The
receivers can have this added either at the time of purchase, or at a later date as an
option. With the Data Logging option enabled, the receiver has available memory, that
facilitates the collection of GPS observations over a period of time, which can be used
with GPS postprocessing software such as Trimble Geomatics Office or Trimble Total
Control, for the computation of control networks and baselines.

SPSx50 Modular GPS Receiver User Guide
Configuring the Receiver Settings
The SCS900 system does not provide support for postprocessed applications. Trimble
recommends that you use either the front panel keypad and display, the Web User
Interface, or (SPS770, SPSx80 only) the GPS Configurator software to configure the
receiver for postprocessed measurement sessions.
Configuring Ethernet Settings
The SPSx50 receiver has an Ethernet port so that the receiver can connect to an
Ethernet network. The receiver can be accessed across the network giving you the
ability to configure and monitor the receiver without needing to connect to the
receiver with a serial cable.
The SPSx50 receiver requires the following Ethernet settings:
•
IP setup: Static or DHCP
•
IP address
•
Netmask
•
Broadcast
•
Gateway
•
DNS address
•
HTTP port
The factory default configuration of the SPSx50 receiver is to use DHCP. Using DHCP
enables the receiver to obtain the IP address, Netmask, Broadcast, Gateway, and DNS
address from the network. The default setting for the HTTP port is 80. The HTTP port
is not assigned by the network. HTTP port 80 is the standard port for web servers. This
allows you to connect to the receiver by entering only the IP address of the receiver in a
web browser. If the SPSx50 receiver is set up to use a port other than 80, you will need
to enter the IP address followed by the port number in a web browser.
Example of connecting to the receiver using port 80: http://169.254.1.0
Example of connecting to the receiver using port 4000: http://169.254.1.0:4000
When an SPSx50 receiver is connected to a
network using DHCP, an IP address is assigned
to the receiver by the network. To verify the IP
address of the receiver, select the up button
from the keypad when the Home screen is
displayed. The display will show the Ethernet IP address as shown.
If your network installation requires the receiver to be configured with a static IP
address, you can configure the Ethernet settings using the web server or the WinFlash
software. The web server can be only used when the receiver is connected to a network
and has a valid Ethernet configuration.

Configuring the Receiver Settings
You should use the WinFlash software to configure the Ethernet settings of a receiver
that is to be connected to a network that requires static IP addresses. If a network
requires static IP addresses, contact the network administrator for the correct settings
for the SPSx50 receiver.
To configure the Ethernet settings using the WinFlash software:
78
1.
Connect the SPSx50 receiver to a computer running the WinFlash software
using the serial cable provided with the receiver.
2.
Turn on the SPSx50 receiver.
3.
On the computer, start the WinFlash software.
4.
From the Device screen, select Trimble SPSx50 Receiver, and then from the PC
serial port list, select the appropriate PC serial port. Click Next:

Enter the network settings (obtain these from your network administrator), and
then click OK:
The Broadcast setting is the IP address that is used to broadcast to all devices on
the subnet. This is usually the highest address in the subnet, which is usually
.255.
