COCOM lim it s
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 this product:
• Immediate access to satellite measurements and navigation results
is disabled when the receiver velocity is computed to be greater than
1,000 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.

Safety Information
Before you use your Trimble product, make sure that you have read and
understood all safety requirements.
Use and care
This product 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.
Ca u t ion – Ope r a t in g or st or in g t h e r e ce ive r ou t side t h e sp e cif ie d t e m pe r a t u r e

Regulations and safety
Some SPS receiver models with Base capability contain an internal radiomodem for transmission or can transmit through an external data
communications radio. Regulations regarding the use of the 410-470 MHz
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.
All SPS receiver models are capable of transmitting data via Bluetooth.
Bluetooth, and 900 MHz1 , (and 2.4 GHz radio-modems - Ja pa n on ly) operate
in license-free bands.
The SNM910 contains an internal Quad-Band GSM 850/900/1800/1900MHz
radio Modem.
Before operating a Trimble GPS receiver or GSM modem, 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 Legal Notices.
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 radio-modem frequency bands. To
comply with those requirements, Trimble may have modified your equipment
to be granted Type approval.
SNM910 Site-Net Modem Getting Started Guide
Unauthorized modification of the units voids the Type approval, the warranty,
and the operational license of the equipment.
Exposure to radio frequency radiation
For 450 MHz radio
Safet y. Exposure to RF energy is an important safety consideration. The FCC
has adopted a safety standard for human exposure to radio frequency
electromagnetic energy emitted by FCC regulated equipment as a result of its
actions in General Docket 79-144 on March 13, 1986.
Proper use of this radio modem results in exposure below government limits.
The following precautions are recommended:
•
DO NOT operate the transmitter when someone is within 20
cm (7.8 inches) of the antenna.
•
DO NOT operate the transmitter unless all RF connectors are
secure and any open connectors are properly terminated.
DO NOT operate the equipment near electrical blasting caps
or in an explosive atmosphere.
•
All equipment must be properly grounded according to
Trimble installation instructions for safe operation.
•
•
All equipment should be serviced only by a qualified
technician.
For license-free 900 MHz radio1

Proper use of this radio modem results in exposure below government limits.
The following precautions are recommended:
•
DO NOT operate the transmitter when someone is within 20
cm (7.8 inches) of the antenna.
The maximum gain of the antenna must not exceed 8 dBi.

Getting Started Guides
For Bluetooth radio
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 20 cm or further from
the human body. The internal wireless radio operates within guidelines found
in radio frequency safety standards and recommendations, which reflect the
consensus of the scientific community. Trimble therefore believes that 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.
For GSM/GPRS radio
Safet y. Exposure to RF energy is an important safety consideration. The FCC
has adopted a safety standard for human exposure to radio frequency
electromagnetic energy emitted by FCC regulated equipment as a result of its
actions in General Docket 79-144 on March 13, 1986.
Proper use of this radio modem results in exposure below government limits.
The following precautions are recommended:
•
DO NOT operate the transmitter when someone is within 28
cm (11 inches) of the antenna.
•
All equipment should be serviced only by a qualified
technician.

listed below. Antennas not included in this list are strictly prohibited for use
with this device. The required antenna impedance is 50 ohms.
11
SNM910 Site-Net Modem Getting Started Guide
The antennas that can be used (country dependent) with the 4 5 0 M H z r a dio
are 0 dBi and 5 dBi whip antennas. The antennas that can be used (country
dependent) with the 9 0 0 M H z radio are 0 dBi, 3 dBi, and 5 dBi whip antennas.
The antennas that can be used (country dependant) with the2 .4 GH z r a dio
are 2 dBi and 8 dBi whip antennas.
To reduce potential radio interference to other users, the antenna type and its
gain should be so chosen so that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that permitted for successful communication.

Changing the Radio module
SPS882 only
Trimble requires that you do not change from one version of a radio door
assembly to another, for the following reasons:
The regulatory compliance requirements will be violated.
Operating such a product is illegal.
•
•
The internal connector on the radio is not intended for
multiple insertions or extractions. It may be damaged or break if
overused.
•
The seal integrity of the whole GPS receiver is compromised
when the radio is removed. Users do not have the facilities to test
the integrity of the seal.
•
If the unit is outside of warranty, you can purchase another
radio door, which must be installed by a Trimble authorized
Service Provider. There are hardware limitations to this, so be
very careful, especially with the 900 MHz doors.

1 PPS
a lm a n a c
Pulse-per-second. Used in hardware timing. A pulse is
generated in conjunction with a time stamp. This defines
the instant when the time stamp is applicable.
A file that contains orbit information on all the satellites,
clock corrections, and atmospheric delay parameters. The
almanac is transmitted by a GPS satellite to a GPS
receiver, where it facilitates rapid acquisition of GPS
signals when you start collecting data, or when you have
lost track of satellites and are trying to regain GPS
signals.
The orbit information is a subset of the
emphemeris/ephemerides data.
Au t oBa se
AutoBase technology uses the position of the receiver to
automatically select the correct base station; allowing for
one button press operation of a base station. It shortens
setup time associated with repeated daily base station
setups at the same location on jobsites.
ba se st a t ion
Also called refer ence st at ion. A base station in
construction, is a receiver placed at a known point on a
jobsite that tracks the same satellites as an RTK rover,
and provides a real-time differential correction message
stream through radio to the rover, to obtain centimeter
level positions on a continuous real-time basis. A base
station can also be a part of a virtual reference station
network, or a location at which GPS observations are
collected over a period of time, for subsequent
postprocessing to obtain the most accurate position for
the location.
be a con
Source of RTCM DGPS corrections transmitted from
coastal reference stations in the 283.5 to 325.0 kHz
range.
BI N EX
BInary EXchange format. BINEX is an operational binary
format standard for GPS/GLONASS/SBAS research
purposes. It has been designed to grow and allow
encapsulation of all (or most) of the information currently
allowed for in a range of other formats.
br oa dca st se r ve r
An Internet server that manages authentication and
password control for a network of VRS servers, and
relays VRS corrections from the VRS server that you
select.
ca r r ie r
A radio wave having at least one characteristic (such as
frequency, amplitude, or phase) that can be varied from
a known reference value by modulation.
ca r r ie r f r e qu e n cy
The frequency of the unmodulated fundamental output of
a radio transmitter. The GPS L1 carrier frequency is
1575.42 MHz.

ca r r ie r ph a se
Is the cumulative phase count of the GPS or GLONASS
carrier signal at a given time.
ce llu la r m od e m s
A wireless adaptor that connects a laptop computer to a
cellular phone system for data transfer. Cellular modems,
which contain their own antennas, plug into a PC Card
slot or into the USB port of the computer and are
available for a variety of wireless data services such as
GPRS.
CM R/ CM R+
Compact Measurement Record. A real-time message
format developed by Trimble for broadcasting corrections
to other Trimble receivers. CMR is a more efficient
alternative to RTCM.
CM Rx
A real-time message format developed by Trimble for
transmitting more statellite corrections resulting from
more satellite signals, more constellations, and more
satellites. Its compactness means more repeaters can be
used on a site.
cova r ia n ce
A statistical measure of the variance of two random
variables that are observed or measured in the same
mean time period. This measure is equal to the product
of the deviations of corresponding values of the two
variables from their respective means.
Also called geodet ic dat um . A mathematical model
designed to best fit the geoid, defined by the relationship
between an ellipsoid and, a point on the topographic
surface, established as the origin of the datum. World
geodetic datums are typically defined by the size and
shape of an ellipsoid and the relationship between the
center of the ellipsoid and the center of the earth.
da t u m
Because the earth is not a perfect ellipsoid, any single
datum will provide a better model in some locations than
in others. Therefore, various datums have been
established to suit particular regions.
For example, maps in Europe are often based on the
European datum of 1950 (ED-50). Maps in the United
States are often based on the North American datum of
1927 (NAD-27) or 1983 (NAD-83).
All GPS coordinates are based on the WGS-84 datum
surface.
de e p disch a r ge
Withdrawal of all electrical energy to the end-point
voltage before the cell or battery is recharged.
D GPS
See real-time differential GPS.
diff e r e nt ia l cor r e ct ion
Differential correction is the process of correcting GPS
data collected on a rover with data collected
simultaneously at a base station. Because the base
station is on a known location, any errors in data
collected at the base station can be measured, and the
necessary corrections applied to the rover data.
Differential correction can be done in real-time, or after
22

the data has been collected by postprocessing.
diff e r e n t ia l GPS
D OP
See real-time differential GPS.
Dilution of Precision. A measure of the quality of GPS
positions, based on the geometry of the satellites used to
compute the positions. When satellites are widely spaced
relative to each other, the DOP value is lower, and
position accuracy is greater. When satellites are close
together in the sky, the DOP is higher and GPS positions
may contain a greater level of error.
PDOP (Position DOP) indicates the three-dimensional
geometry of the satellites. Other DOP values include
HDOP (Horizontal DOP) and VDOP (Vertical DOP), which
indicate the accuracy of horizontal measurements
(latitude and longitude) and vertical measurements
respectively. PDOP is related to HDOP and VDOP as
follows: PDOP² = HDOP² + VDOP².
du a l- fr e qu e n cy GPS
A type of receiver that uses both L1 and L2 signals from
GPS satellites. A dual-frequency receiver can compute
more precise position fixes over longer distances and
under more adverse conditions because it compensates
for ionospheric delays.
EGN OS
European Geostationary Navigation Overlay Service. A
satellite-based augmentation system (SBAS) that
provides a free-to-air differential correction service for
GPS. EGNOS is the European equivalent of WAAS, which
is available in the United States.
e le v a t ion m a sk
The angle below which the receiver will not track
satellites. Normally set to 10 degrees to avoid
interference problems caused by buildings and trees,
atmospheric issues, and multipath errors.
e llip soid
An ellipsoid is the three-dimensional shape that is used
as the basis for mathematically modeling the earth’s
surface. The ellipsoid is defined by the lengths of the
minor and major axes. The earth’s minor axis is the polar
axis and the major axis is the equatorial axis.
A list of predicted (accurate) positions or locations of
satellites as a function of time. A set of numerical
e m ph e m e r is/ e p h e m e r id e s parameters that can be used to determine a satellite’s
position. Available as broadcast ephemeris or as
postprocessed precise ephemeris.
e poch
The measurement interval of a GPS receiver. The epoch
varies according to the measurement type: for real-time
measurement it is set at one second; for postprocessed
measurement it can be set to a rate of between one
second and one minute. For example, if data is measured
every 15 seconds, loading data using 30-second epochs
means loading every alternate measurement.
fe a t ur e
A feature is a physical object or event that has a location
in the real world, which you want to collect position
and/or descriptive information (attributes) about.
23
SNM910 Site-Net Modem Getting Started Guide
Features can be classified as surface or non-surface
features, and again as points, lines/breaklines, or
boundaries/areas.
fir m w a r e
The program inside the receiver that controls receiver
operations and hardware.
GLON ASS
Global Orbiting Navigation Satellite System. GLONASS is
a Soviet space-based navigation system comparable to
the American GPS system. The operational system
consists of 21 operational and 3 non-operational satellites
in 3 orbit planes.
GN SS
Global Navigation Satellite System.
GSOF
General Serial Output Format. A Trimble proprietary
message format.
H D OP
Horizontal Dilution of Precision. HDOP is a DOP value that
indicates the accuracy of horizontal measurements. Other
DOP values include VDOP (vertical DOP) and PDOP
(Position DOP).
Using a maximum HDOP is ideal for situations where
vertical precision is not particularly important, and your
position yield would be decreased by the vertical
component of the PDOP (for example, if you are
collecting data under canopy).
L1
The primary L-band carrier used by GPS and GLONASS
satellites to transmit satellite data.
L2
The secondary L-band carrier used by GPS and GLONASS
satellites to transmit satellite data.
L2 C
A modernized code that allows significantly better ability
to track the L2 frequency.
L5
The third L-band carrier used by GPS satellites to
transmit satellite data. L5 will provide a higher power
level than the other carriers. As a result, acquiring and
tracking weak signals will be easier.
Loca t ion RTK
Some applications such as vehicular-mounted site
supervisor systems do not require Precison RTK accuracy.
Location RTK is a mode in which, once initialized, the
receiver will operate either in 10 cm horizontal and 10 cm
vertical accuracy, or in 10 cm horizontal and and 2 cm
vertical accuracy.
M ou n t poin t
Every single NTripSource needs a unique mountpoint on
an NTripCaster. Before transmitting GNSS data to the
NTripCaster, the NTripServer sends an assignment of the
mountpoint.
M ovin g Ba se
Moving Base is an RTK positioning technique in which
both reference and rover receivers are mobile.
Corrections are sent from a “base” receiver to a “rover”
receiver and the resultant baseline (vector) has
centimeter-level accuracy.
24
Glossary
M SAS
MTSAT Satellite-Based Augmentation System. A satellitebased augmentation system (SBAS) that provides a freeto-air differential correction service for GPS. MSAS is the
Japanese equivalent of WAAS, which is available in the
United States.
m ult ipa t h
Interference, similar to ghosts on an analog television
screen, that occurs when GPS signals arrive at an
antenna having traversed different paths. The signal
traversing the longer path yields a larger pseudorange
estimate and increases the error. Multiple paths can arise
from reflections off the ground or off structures near the
antenna.
N M EA
National Marine Electronics Association. NMEA 0183
defines the standard for interfacing marine electronic
navigational devices. This standard defines a number of
'strings' referred to as NMEA strings that contain
navigational details such as positions. Most Trimble GPS
receivers can output positions as NMEA strings.
N Tr ip Pr ot ocol
Networked Transport of RTCM via Internet Protocol
(NTrip) is an application-level protocol that supports
streaming Global Navigation Satellite System (GNSS) data
over the Internet. NTrip is a generic, stateless protocol based
on the Hypertext Transfer Protocol (HTTP). The HTTP
objects are extended to GNSS data streams.
N Tr ipCa st e r
The NTripCaster is basically an HTTP server supporting a
subset of HTTP request/response messages and adjusted
to low-bandwidth streaming data. The NTripCaster
accepts request messages on a single port from either
the NTripServer or the NTripClient. Depending on these
messages, the NTripCaster decides whether there is
streaming data to receive or to send.
Trimble NTripCaster integrates the NTripServer and the
NTripCaster. This port is used only to accept requests
from NTripClients.
N Tr ipClie n t
N Tr ipSe r ve r
An NTripClient will be accepted by and receive data from
an NTripCaster, if the NTripClient sends the correct
request message (TCP/UDP connection to the specified
NTripCaster IP and listening port).
The NTripServer is used to transfer GNSS data of an
NTripSource to the NTripCaster. An NTripServer in its
simplest setup is a computer program running on a PC
that sends correction data of an NTripSource (for
example, as received through the serial communication
port from a GNSS receiver) to the NTripCaster.
The NTripServer - NTripCaster communication extends
HTTP by additional message formats and status codes.
N Tr ipSou r ce
The NTripSources provide continuous GNSS data (for
example, RTCM-104 corrections) as streaming data. A
single source represents GNSS data referring to a specific
location. Source description parameters are compiled in
25

the source-table.
Om n iSTAR
PD OP
The OmniSTAR HP/XP service allows the use of new
generation dual-frequency receivers with the OmniSTAR
service. The HP/XP service does not rely on local
reference stations for its signal, but utilizes a global
satellite monitoring network. Additionally, while most
current dual-frequency GPS systems are accurate to
within a meter or so, OmniSTAR with XP is accurate in 3D
to better than 30 cm.
Position Dilution of Precision. PDOP is a DOP value that
indicates the accuracy of three-dimensional
measurements. Other DOP values include VDOP (vertical
DOP) and HDOP (Horizontal Dilution of Precision).
Using a maximum PDOP value is ideal for situations
where both vertical and horizontal precision are
important.
post p r oce ssin g
Postprocessing is the processing of satellite data after it
has been collected, in order to eliminate error. This
involves using computer software to compare data from
the rover with data collected at the base station.
Also known as r eal- t im e differ ent ial corr ect ion or DGPS.
Real-time differential GPS is the process of correcting
GPS data as you collect it. Corrections are calculated at a
base station and then sent to the receiver through a radio
link. As the rover receives the position it applies the
corrections to give you a very accurate position in the
field.
r e a l- t im e dif fe r e n t ia l GPS Most real-time differential correction methods apply
corrections to code phase positions.
While DGPS is a generic term, its common interpretation
is that it entails the use of single-frequency code phase
data sent from a GPS base station to a rover GPS
receiver to provide sub-meter position accuracy. The
rover receiver can be at a long range (greater than 100
kms (62 miles)) from the base station.
r ove r
A rover is any mobile GPS receiver that is used to collect
or update data in the field, typically at an unknown
location.
Rovin g m ode
Roving mode applies to the use of a rover receiver to
collect data, stakeout, or control earthmoving machinery
in real time using RTK techniques.
RTCM
Radio Technical Commission for Maritime Services. A
commission established to define a differential data link
for the real-time differential correction of roving GPS
receivers. There are three versions of RTCM correction
messages. All Trimble GPS receivers use Version 2
protocol for single-frequency DGPS type corrections.
Carrier phase corrections are available on Version 2, or
on the newer Version 3 RTCM protocol, which is available
on certain Trimble dual-frequency receivers. The Version
3 RTCM protocol is more compact but is not as widely
26
Glossary
supported as Version 2.
RTK
real-time kinematic. A real-time differential GPS method
that uses carrier phase measurements for greater
accuracy.
SBAS
Satellite-Based Augmentation System. SBAS is based on
differential GPS, but applies to wide area
(WAAS/EGNOS/MSAS) networks of reference stations.
Corrections and additional information are broadcast via
geostationary satellites.
sig n a l- t o- n oise r a t io
SNR. The signal strength of a satellite is a measure of the
information content of the signal, relative to the signal’s
noise. The typical SNR of a satellite at 30° elevation is
between 47 and 50 dBHz.
sk yplot
The satellite skyplot confirms reception of a differentially
corrected GPS signal and displays the number of satellites
tracked by the GPS receiver, as well as their relative
positions.
SN R
See signal-to-noise ratio.
Sou r ce - t a ble
The NTripCaster maintains a source-table containing
information on available NTripSources, networks of
NTripSources, and NTripCasters, to be sent to an
NTripClient on request. Source-table records are
dedicated to one of the following:
•
data STReams (record type STR)
•
CASters (record type CAS)
•
NET)
NETworks of data streams (record type
All NTripClients must be able to decode record type STR.
Decoding types CAS and NET is an optional feature. All
data fields in the source-table records are separated
using the semicolon character.
t r ip le fr e qu e n cy GPS
A type of receiver that uses three carrier phase
measurements (L1, L2, and L5).
UTC
Universal Time Coordinated. A time standard based on
local solar mean time at the Greenwich meridian.
VRS
W AAS
Virtual Reference Station. A VRS system consists of GPS
hardware, software, and communication links. It uses
data from a network of base stations to provide
corrections to each rover that are more accurate than
corrections from a single base station.
To start using VRS corrections, the rover sends its
position to the VRS server. The VRS server uses the base
station data to model systematic errors (such as
ionospheric noise) at the rover position. It then sends
RTCM correction messages back to the rover.
Wide Area Augmentation System. WAAS was established
by the Federal Aviation Administration (FAA) for flight
and approach navigation for civil aviation. WAAS
27
SNM910 Site-Net Modem Getting Started Guide
improves the accuracy and availability of the basic GPS
signals over its coverage area, which includes the
continental United States and outlying parts of Canada
and Mexico.
The WAAS system provides correction data for visible
satellites. Corrections are computed from ground station
observations and then uploaded to two geostationary
satellites. This data is then broadcast on the L1
frequency, and is tracked using a channel on the GPS
receiver, exactly like a GPS satellite.
Use WAAS when other correction sources are unavailable,
to obtain greater accuracy than autonomous positions.
For more information on WAAS, refer to the FAA website
at http://gps.faa.gov.
The EGNOS service is the European equivalent and MSAS
is the Japanese equivalent of WAAS.
W GS- 8 4
28
World Geodetic System 1984. Since January 1987, WGS84 has superseded WGS-72 as the datum used by GPS.
The WGS-84 datum is based on the ellipsoid of the same
name.
