Handle Global Positioning Receivers
and Brackets Safely
TS249 —UN—23AUG88
Falling while installing or removing a global positioning
receiver can cause serious injury. Use a ladder or platform
to easily reach a mounting location.
Use sturdy and secure footholds and handholds. Do not
install or remove the receiver in wet or icy conditions.
The receiver mast used on implements is heavy and can
be awkward to handle. Two people are required when
mounting locations are not accessible from the ground or
from a service platform. Use proper lifting techniques and
wear proper protective equipment.
Do not install or service a RTK base station on a tower or
other tall structure unless it provides sturdy and secure
steps and railings. If necessary, use a professional
climber.

Prevent Electrical Shock and Fires
If installing with the power amplifier option, prevent
electrical shock or fire by using a 14 AWG heavy­duty
electrical cord with 15 amp rating suitable for outdoor use.
When using an AC/DC converter, always connect to a 120
V outlet protected by Ground Fault Interrupter (GFI).

Prevent injury from exposure to high radio frequency fields
at an RTK base station. Do not touch the antenna while
the system is transmitting. Always disconnect power to the
receiver, radio and amplifier before installing or servicing.
While the RTK base station amplifier and radio are
operating together, stay at least 6 ft. (1.8 m) away from
the radio antenna for temporary exposure and 12 ft. (3.6
m) away for continual exposure.
While using the RTK base station radio without the
amplifier option, stay at least 8 in. (20 cm) away from the
radio antenna for temporary exposure and 15 in. (40 cm)
away for continual exposure.

Licensing of 450 MHz RTK Base
Licensing of 450 MHz RTK Base
The 900 MHz RTK product sold by John Deere uses ISM
band radios. These radios do not require licensing by the
end user. The radios are limited to a specific frequency
range and 1 W maximum output power. While this system
works for the majority of applications, the reliability of the
RTK link may become limited when passing through trees
and dense foliage.
The intent of 450 MHz RTK is to increase the range and
reliability of the RTK link. To overcome the attenuation
of adverse field conditions, transmission power greater
than 900 MHz RTK is needed. While there is some added
benefit from using a radio with lower frequency and longer
wavelength, the signal strength is the dominant factor in
the radio link reliability. To legally transmit at a higher
power, 450 MHz RTK uses a licensed band radio. The end
user of the licensed band transmitting radio is responsible
for obtaining and maintaining a valid site license from the
local spectrum authorities. In 450 MHz RTK system, this
requires a license for each base station.
Vehicle radios in 450 MHz system are not transmitters.
Since they only receive corrections from the base, 450
MHz vehicle radios do not required a site license.
An end user can apply for the license by applying directly
to the local spectrum authority:
Country
Australia
Authority
Australian Communications and Media Authority
(ACMA)
Canada
Industry Canada (IC)
United States
Federal Communications Commission
New Zealand
Radio Spectrum Management Group
An end user can also apply with the aid of a frequency
coordinator. A frequency coordinator is a private company
that has been certified by the local frequency spectrum
authority to recommend and aid in the application for a
licenses. For a fee, these third party coordinators will
reduce the complexity and confusion of the application
process. However, the final responsibility of the license
still resides with the end user.
Check www.StellarSupport.com for country specific
instructions on how to obtain a site license.
IMPORTANT: Please contact your local radio
authorities or partnering frequency coordinator
for region specific regulations and licensing.
License Renewal Scams
After being granted a license for 450 MHz RTK radio,
base station operators should be aware of license
renewal scams. Spectrum licenses are public record.
Other companies could retrieve licensee information
and then mail current license holders offers to prepare
applications for license renewal. The letters contain
warnings that there will be monetary penalties if the
licensee does not comply. These companies are not
affiliated with government spectrum authorities. They are
taking advantage of the public record and the licensee’s
desire to comply with the law. Their intention is to charge
a “processing” fee on top of the actual amount that a
licensee would pay for renewal. While it is important to
not let your license expire, licensees should work directly
with their local spectrum authority or a certified frequency
coordinator. Internet searches of the companies involved
usually identify if the company is relevant.

RTK Base Station Setup
System Overview
The StarFire™ RTK system consists of a local base
station permanently mounted on a structure that transmits
high accuracy corrections to the vehicle’s StarFire™
receiver using 450 MHz RTK radios and an optional
amplifier. The StarFire™ receiver on the RTK equipped
vehicle must have a direct line of sight with the base
station in order to receive the RTK signal. While the higher
transmission power and longer wavelength of 450 MHz
RTK aids in the transmission through trees and foliage, it
will not penetrate through earth in hilly terrains.
beyond 20 km (12 mi.), degraded accuracy will occur and
it may take longer to initially acquire the RTK signal.
IMPORTANT: The 900 MHz and 450 MHz RTK radio
systems are not compatible. Vehicles with 450
MHz radios must receive corrections from a
450 MHz radio attached to the base. Likewise,
vehicles with 900 MHz radios installed must
receive there corrections from a base with a
900 MHz radio installed. Different radio models
can not communicate with each other since
they transmit on different frequencies.
Performance of the RTK correction is related to the
operating distance from the base station. When operating

Vehicle Receiver
Position receiver with integrated RTK radio module is
located on top of machine. Position receiver combines
the global positioning signals it receives with the RTK
differential correction via the radio link to provide accurate
position information to the GreenStar™ system.
The receiver has a dedicated operating mode (Vehicle
Mode). Refer to Operating Mode—RTK in Section
StarFire iTC for setup of the receiver on vehicle.
IMPORTANT: The antenna must be installed before
the radio module is powered ON.
PUPC000011 —UN—03DEC09
Avoid water intrusion by keeping the antenna
attached whenever possible.
Removing the antenna while powered may
damage the radio module.
The 450 MHz RTK system is only compatible with the
deluxe shroud. This may require a conversion bracket
for installation.

RTK Base Station Setup
Base Station Setup
The base station is the most critical part of RTK system.
During installation, care must be taken to ensure the base
has problem­free operation. There are two issues that
are responsible for most problems with a base station:
Shading and Multipathing. If a base station experiences
one of these problems, it could be detrimental to your RTK
operation. These issues are shared with the 900 MHz
RTK system. Mitigation techniques have already been
documented in the standard StarFire iTC – RTK manual
that came with the iTC receiver. This manual provides
detailed recommendations to minimizing these errors.
Base station operating mode can be either Absolute
Survey Base Mode or Quick Survey Base Mode.
NOTE: When using this option, it may be necessary to
install a higher­gain antenna and/or the optional
amplifier to compensate for loss.

Always mount the radio antenna vertically to make sure
that the RTK signal is radiating outwards. If the antenna is
at an angle, it may cause the data received at the vehicle
to be lower than expected.
IMPORTANT: If using coaxial cable between the
radio and the antenna, you need to use
the lowest­loss cable available or you may
suffer RTK radio link range issues.
NOTE: The 450 MHz RTK whip antenna, PF81464, looks
similar to 900 MHz and 869 MHz RTK whip antennas.
To differentiate, it has a white stripe near its tip.
• Attach the RTK radio in a secured location and run

SHOCK AND FIRES and AVOID EXPOSURE
TO HIGH RADIO FREQUENCY FIELDS in
the SAFETY section.
The primary reason for 450 MHz RTK is to provide a more
robust RTK data link. Signal strength is the dominant
factor in the link reliability and range. For areas where
there are trees and other foliage, John Deere offers an
optional in­line amplifier.
PUPC000027 —UN—06DEC09
The PF81443 amplifier is a UHF RF power amplifier
intended for use in 450 MHz RTK system. It is not
intended to be used with 900 MHz RTK or any other
applications. The amplifier can deliver RF power from 0
to 50 W proportional to the 0 to 2 W input from 450 MHz
RTK Radio. It covers a frequency range from 450 MHz to
470 MHz. This higher signal strength provides greater
range from the base and increased coverage in areas
with dense foliage and trees.
This amplifier is inserted between the radio and the base
antenna. The amplifier has been designed to function
outdoors attached to its mounting plate with sun shade.
Mount the amplifier in an area where air can freely
circulate around it. If possible, mount in a location shaded
from direct sunlight.
Operation of the amplifier inside an enclosure is not
recommended. Poor ventilation within the box can
cause the amplifier to overheat. While this would not
permanently damage the amplifier, it would cause it to

stop amplification. The output signal would no longer be
strong enough for the vehicles in the field to receive.

There are 3 connections located at the bottom of the
power amplifier:
1. 12 VDC power input
2. RF input via TNC connector
3. RF output via N­Type connector
The connectors should only be finger­tight. Using
tools can over tighten and damage the RF and power
connectors.
A 13.8 V power supply capable of providing a constant
10 amp to the amplifier is required. Amplifier operation
with insufficient voltage can lead to higher amplifier
operating temperatures. Insufficient current can cause the
amplifier to not amplify or only partially amplify the RF
signal. These conditions result in incomplete or no RTK
transmissions being received by the vehicle.
IMPORTANT: Make sure the antenna and coax
are attached before the amplifier module is
powered ON or damage to the amplifier could

occur. Do not remove the coax or antenna
while the amplifier is powered ON. Avoid
water intrusion by keeping the connections
attached whenever possible.
Make sure the power connector is attached
and unpowered when handling the RF IN and
RF OUT connectors. The ground provided by
the power connector protects the amplifier
against possible electrostatic discharge.

PUPC000007 —UN—03DEC09
The ability to use a single base station is a substantial
reduction in cost and maintenance. The drawback to this
method is that only one radio can be configured at a time.
A single RS232 port is used by the StarFire™ receiver
to communicate with an RTK radio. Two radios can
simultaneously receive RTK corrections from the receiver.
Unfortunately, the receiver can not process simultaneous
messages sent from the radios. The two radios send
different messages and interfere. To ensure that this
interference does not occur, the dual radio harness has
the radio send wire in only one branch.
To prevent network connection errors, a specific
procedure must be followed when configuring a base
station supporting two radios:
1. Connect the Dual Radio Harness to the StarFire™
Receiver.
4­Wire RTK Connector
2. Power the base station StarFire™ Receiver with only
900 MHz connected to 4­wire Deutsch connector. The
receiver must have clear view of the sky.
3. Once the receiver determines its position, configure
900 MHz radio Network ID and Radio Channel.
PUPC000008 —UN—03DEC09
4. Power down the base station StarFire™ Receiver.
5. Disconnect 900 MHz radio and then connect 450 MHz
radio to the 4­wire Deutsch connector.
6. Once the receiver determines its position and
recognizes the radio, configure 450 MHz radio to
comply with the site license.
7. Power down the receiver.
8. With 450 MHz radio still attached to the 4­Wire
Deutsch connector, connect the 900 MHz radio to the
3­wire Deutsch connector.
3­Wire RTK connector
Vehicles using 900 MHz will see fewer messages
received when using a dual radio base station as their
correction source. The mandatory narrow bandwidth of
the licensed band radio results in a slower over­the­air
baud rate. 450 MHz RTK uses the same message rates
for most configurations. However, the message rate had
to be reduced for the default narrowband settings to 2
messages per second.
9. Power the base station.
IMPORTANT: Do not attempt to change the radio
parameters while both radios are attached.
This can corrupt the configuration of 900 MHz
radio and may cause problems with rovers
liking to it. If this does occur, reconfigure the
radios with the process given above.
During normal operation, ensure that 450 MHz
radio is connected to the 4­wire connector
and that 900 MHz radio is connected to the
3­wire connector. If the receiver detects a
900 MHz radio, 450 MHz radio link may be
compromised. At its lowest data speed, the
450 MHz radio does not have the capacity to
transmit corrections at the 900 MHz radio rate.

The 900 MHz RTK message rates are designed with extra
redundancy. System performance is not compromised
at 2 Hz message rate. Both 900 MHz and 450 MHz
RTK systems have sufficient redundancy to ensure
RTK reliability and accuracy. The diagnostic reading
on vehicles with 900 MHz radios will be based on 5 Hz
message rate. The result is that 900 MHz customers

applications without relying on visual reference for track
position to align using Shift Track feature. Track 0 must
be stored using Current Track 0 in Guidance Setup – Set
Track 0 in order to follow previously used tracks. Absolute
Base Mode requires 24 hour self survey to be conducted
on location before first use. After survey is completed,
base station will then transmit corrections. If base station
is moved to another position and then returned to original
surveyed position, it is very important that base station is
mounted in exact same position. Any difference between
original surveyed position and mounted position will
result in offset of corrected position. For this reason, it
is important to mount receiver to a fixed position like a
building or post mounted in concrete.

Congure Radio Screen
The frequency and power settings for 900 MHz RTK are
fixed to comply with ISM band requirements. For 450
MHz RTK, these settings can be controlled and are the
responsibility of the end user. Besides the Network ID
on the RTK Main screen, there are four parameters that
manage the radio link between the vehicle and Base:
Radio Frequency, Bandwidth, Data Rate and Power.
of the radio. The signal to noise increases with larger
bandwidth. A larger bandwidth is therefore related to
higher baud rates. Two Data Rate settings are provided
for each bandwidth. L2 is the lower speed and provides
the maximum radio link range. L4 has twice the speed,
but comes at the cost of reduced range.
Press: MENU Button >> StarFire iTC™ Button >> RTK
Softkey >> Radio Configure Button
The Radio Frequency is the center frequency of the link
shared between the Base and Rover.
The Bandwidth is the range of the frequency that the
transmitted signal is modulated. This range, or band, is
centered about the Radio frequency. For example, if the
radio is set at 460 MHz with a bandwidth of 12.5 kHz, then
the radio link will be contained within 460 Âą 0.0125 MHz.
The Data Rate is the over­the­air speed of the data link.
This baud rate is directly related to the bandwidth setting
The output power control is only displayed when the
receiver is set to Quick Survey Base or Absolute base
Operating Modes. When the receiver is set as a Vehicle,
the radio output power is set to its lowest output power

Diagnostic LEDs
A key aid to gain insight into the working state of the 450
RTK system are the LEDs on both the RTK radio and
the in­line amplifier. These diagnostic lights can be used
during setup, maintenance and troubleshooting.

450 MHz RTK Radio LEDs
PUPC000021 —UN—06DEC09
There are three radio LEDs. They can be seen after the
radio has been powered. They are viewed through a
small window on the front of the radio.
The LEDs can be used to determine
□ Is the radio powered?
□ Is the radio is configured as a Base Station or a vehicle?
□ Is the radio searching or linked?
□ Is the radio in configuration mode?
The radio enters configuration mode when parameters are
being read/set or when diagnostics are being retrieved.
While in configure mode, the radio does not transmit or
receive communications.

Amplifier LEDs
There are four amplifier LEDs. They are located on the
side of the amplifier.
The LEDs can be used to determine
□ Is the amplifier powered?
□ Is there an internal failure?
□ Is the radio signal being amplified?
□ Is the amplifier setup causing it to overheat?
□ Is the antenna or its connection path faulty?
The LEDs operate in two states: Start Up and Operation.
PUPC000031 —UN—07DEC09
After the amplifier is initially powered, the amplifier
strobes through each LED sequentially. This rapid
flashing sequence indicates that the internal firmware test
sequence is initiated. It checks the power to the unit and
the integrity of internal components.
The outcome of a successful startup test sequence results
in only the PWR LED on. The outcome of an unsuccessful
startup sequence results in the PWR LED and any of the
red LEDs on. These red LEDs indicate a failure.
During normal operation after a successful startup, each
amplifier LED has a specific meaning.
Power LED Indicates that the amplifier has DC power.
TX LED Indicates that an RF signal is being actively
amplified and transmitted. This light blinking indicates
normal function.
O/T LED Indicates that the unit has exceeded its internal
temperature limits. When this light is on, the unit with
cease amplification. This allows the unit to cool and
prevents permanent damage.
Amplier LED
VSWR LED Indicates that the antenna path is faulty.
When this light is on, the unit will cease amplification. This
prevents the output power from being reflected back into

450 MHz RTK Accuracy
The accuracy of 450 MHz RTK is the same as 900 MHz
RTK. The UHF link is more robust, but the content sent by
the StarFire RTK™ base to the vehicle is identical.
StarFire RTK™ delivers 1 in. repeatable accuracy. RTK
accuracy is expressed as an absolute value (without +/­)
because RTK performance is not subject to GPS drift over
time. RTK accuracy levels are described on a static basis
measured at the vehicle receiver, 68 percent of the time,
within 12 mi. (20 km) line of sight with the base station,
assuming unobstructed view of the sky, favorable PDOP,
and correct base station setup.

PC9393 —UN—23OCT06
Line of Sight
Line of sight is the direct path between two points,
free of obstacles. For the RTK application, this is the
line between the base and vehicle antennas. Typical
obstructions include:
• Trees and foliage
• Buildings or other man­made objects
• Terrain variation, such as hills or valleys
• Curvature of the Earth
In order to maintain a good RTK Radio link, the antenna
must be mounted high enough to radiate over the earth’s
curvature and any obstacles. As shown in the figure, the
curve of the earth can block the signal from the RTK link.
If the radiating base station radio antenna is mounted too
low, the broadcasting range will be drastically reduced.
The higher RF power of 450 MHz RTK will reduce
attenuation due to plants and small variations in terrain.
Blockage due to man­made objects can be reduced
through planning of the base antenna location. Similar
to analysis performed to locate the StarFire™ receiver
installation, the transmitting antenna should be located
away from nearby obstructions.
To deal with obstructions away from the base, small terrain
variations and the curvature of the Earth, the antenna
should be placed as high as possible. The local spectrum
authority will limit the range and potential interference of
the base station signal by setting a maximum power and
maximum antenna height. End users should install their
base antenna to the maximum height allowed for best
performance.
StarFire RTK™ retains its published accuracy to 12 mi.
(20 km). If consistent with the granted site license, it is
recommended that antennas are mounted ≥ 30 m (100
ft.) to ensure the full range of coverage. The table below
relates the base antenna height to the line­of­sight to the
base radio horizon.

450 RTK Performance
12.5 kHz versus 25 kHz Bandwidth
There are two possible bandwidths that can be set in the
450 MHz RTK radio:
25 kHz
Wideband
12.5 kHz
Narrowband
The 25 kHz bandwidth delivers twice the baud rate of the
12.5 kHz. Wide bands have more data capacity and faster
message transmission than narrow bands. In the RTK
system, this results in a more robust data link. However,
the disadvantage to using a larger bandwidth is that fewer
licensed frequencies are available to applicants. To more
efficiently use the available frequencies, some spectrum
authorities are transitioning from older wideband licensing
plans to narrowband licensing plans.
For example, in the United States the FCC has established
January 1, 2013 as the deadline for migration to 12.5 kHz
technology. Applications for wideband operations (25
kHz channels) will be accepted until January 1, 2011. All
existing Part 90 radio systems operating on frequencies
between 150­512 MHz have eight years to convert those
systems either to 12.5 kHz bandwidth or to a technology
that provides one voice path per 12.5 kHz of bandwidth or
provides a data rate of 4800 bps per 6.25 kHz.
SH20560,000012A ­19­08DEC09­1/1
L2 versus L4 GFSK Modulation
The 450 MHz RTK radio is a digital transmitter. There are
two possible modulation techniques that can be set in 450
MHz RTK radio: Level 2 (L2) or Level 4 (L4) Gaussian
Frequency­Shift Keying (GFSK).
When transmitting with L2 modulation, 1’s and 0’s are
sent by shifting the frequency between two possible
states about the center frequency within the bandwidth of
the radio. The “Gaussian” term refers to a technique of
smoothing the transition between the two frequencies.
When transmitting with L4 modulation, the radio shifts
between four frequencies about the center frequency.
This allows four different symbols to be sent during a
single transmission: 00,01,10,and 11. This results in 2x
the over­the­air speed as the L2 modulation technique.
The drawback is that the signal to noise is lower with
the L4 technique relative to the L2. This is because the
vehicle radio must differentiate between 4 frequencies
instead of only 2.
The default modulation for the 450 MHz RTK is L2. This
provides the greatest RTK range. L4 will be an advantage
in selected applications. One example is operation near
the base where small objects frequently block the line
of sight. Here the signal strength is sufficient for L4.
The higher baud rate results in short transmission times.
These messages then have a lower probability of being
blocked.
SH20560,000012B ­19­08DEC09­1/1
Operation of Vehicle Next to Base
Depending on the base station setup, operation of
vehicles directly under or next to the base may be limited.
The 450 MHz system has both higher power and higher
signal sensitivity than standard RTK. A consequence of
this is that radio signals in the immediate vicinity of the
transmitter may be too strong for the receiving radios. For
base stations that serve vehicles at both ≥20 km and ≤
1 km from the base, it may be necessary to add inline
RF attenuators to the rovers operating directly under
the base. Attenuator specifications: RF load of 15 dBm,
capable of 2W, inline female TNC to male TNC.
