900 MHz RTK—Base Station Setup
System Overview
The StarFire™ RTK system consists of a local base
station placed in a eld or mounted on a structure that
transmits high accuracy corrections to the vehicle StarFire
receiver using RTK radios. 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.
Performance of the RTK system is related to the operating
distance from the base station. When operating beyond
20 km (12 miles), degraded accuracy will occur and it may
take longer to initially acquire the RTK signal.
A repeater, which is simply an RTK radio supplied with 12
volts of power, can be used to receive the base station
signal and establish a new line of sight point. However,
performance limitations can still be expected if trying to use
the repeater to transmit the RTK signal to a vehicle that is
farther than 20 km (12 miles) away from the base station.
NOTE: Old antennas from past receivers are not
compatible with the StarFire 3000 receiver.
Receiver—On Vehicle
Position receiver with integrated RTK radio module is
located on top of machine. Position receiver receives
global positioning and differential correction signal through
a single receiver and integrates signal for use with system.
PC12123 —UN—11JUN09
The receiver has a dedicated operating mode (Vehicle
Mode). Refer to “Operating Mode—RTK” in “StarFire
3000” Section for setup of the receiver on vehicle.
IMPORTANT: The antenna must be installed before
the radio module is powered ON.
Avoid water intrusion by keeping the antenna
attached whenever possible.
Removing the antenna while transmitting
may damage the radio module.
NOTE: Actual receiver position may vary with the use of
an Original Shroud or Deluxe Shroud bracket.

900 MHz RTK—Base Station Setup
Receiver—On Base Station
The base station is the most critical part of an RTK system.
During installation, care must be taken to ensure the base
has problem-free 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. Although it may not be possible to locate
a base station in an ideal location, this guide is aimed at
helping to dene the best option available.
Base station operating mode can be either Absolute
Survey Base Mode or Quick survey Base Mode. Refer to
“Operating Mode—RTK” in “StarFire 3000” Section for
setup of the receiver on base station.
Refer to “Base Station Operation and Setup” in “StarFire
3000” Section for proper use and setup of the base station.

Repeater Radio
The radio can be congured to act separately as a
repeater. A repeater is required if obstructions (i.e. trees,
hills, etc.) exist between the base station and vehicle(s) or
if base station is too far away from the vehicles.
A repeater consists of:
Radio (congured as a repeater)
•
Harness
•
Mounting Bracket
•
12 Volt Power Source
•
Tripod or wall mount cradle
•
IMPORTANT: A repeater can only be used to repeat
a signal from a base station to a vehicle.
Therefore, a repeater cannot be used in a
''daisy chain,'' repeating the signal from
one repeater to another.
Refer to “Repeater—RTK” in “StarFire 3000” Section to
properly congure radio as repeater.

900 MHz RTK—Base Station Setup
Installation of the RTK radio and antenna
After installing the base station receiver, installing the
radio in a location to best maximize the output can be
a challenge. Below are four options currently available
through John Deere.
Leave the RTK radio in its original conguration
•
attached directly behind the base station receiver.
- Use a repeater as part of the base station. Install a
radio with the base station receiver.
- Install a Repeater radio (available through whole
goods or parts) in an elevated location.
The base station will then send the RTK data to the
•
repeater and the repeater will then transmit that data
out to the repeater , and vehicle on the network. This
will eliminate other repeaters in the system.
NOTE: Additional repeaters cannot be run off of the
central repeater. In areas with heavy foliage or
uneven terrain, this setup method is not advised.
Use 92 m (300 ft) extension harness PF80821 to move
•
the radio from the back of the base station receiver to
an elevated position.
NOTE: Use extension harness PF80821.
Use installation instructions provided with
extension harness PF80821 to ensure proper
grounding and wiring according to the installation
instructions. This harness has built in protection
for both the radio and receiver for unwanted static
electricity developed on the harness.
Attach the RTK radio in a safe and unobstructed
•
location, Connect radio and antenna using coaxial cable.
IMPORTANT: The antenna must be installed before
the radio module is powered ON.
Avoid water intrusion by keeping the antenna
attached to the radio whenever possible.
Removing the antenna while transmitting
may damage the radio module.
IMPORTANT: If using a coaxial cable between the
radio and antenna, use the lowest-loss cable
available to avoid RTK radio link range issues.
NOTE: When using this option, it may be
necessary to install a higher-gain antenna
to compensate for loss.
NOTE: Old antennas from past receivers are not
compatible with the StarFire 3000 receiver.
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.

Installing and operation of the Base Station Receiver.
The base station is the most critical part of the RTK
operation. Setting up a base station correctly is vital to the
operation of the RTK system. If the Base Station Receiver
is setup in a questionable location, the receiver could
have two separate issues; Shading and Multipathing.
Shading:
To ensure proper operation of a RTK base station, the
GPS Receiver must have a clear view of the sky in all
directions above 5 degrees off the horizon. Both the base
receiver and the vehicle receiver will use any satellites
that are above 5 degrees off the horizon. If a base station
receiver cannot use a satellite above 5 degrees, then all
vehicles operating on that base station also cannot use
that blocked satellite. This is called Shading of the base
station. If enough shading occurs, the RTK system may
become inaccurate. Many things can cause shading, such
as buildings, towers, poles, and grain legs.

900 MHz RTK—Base Station Setup
When selecting a base station location, there are three
main points to look for: rigidity, good view of the sky,
and few reective objects. The base station provides
corrections to the vehicle receiver based on the xed
known position which is surveyed in with an absolute
survey or quick survey. Any motion of the base station
receiver will translate directly to the vehicle position.
Mount the base station on a rigid structure, such as the
pole in the photo. When mounting on a structure such as
a building, the receiver should generally be installed 2
meters above the highest point.

Multipathing
Signal reections are another important error source
for base stations that should be minimized. Reected
signals also reach the base station receiver and make
the satellite range measurement longer. Reections can
even interfere with the direct signal enough so that the
receiver will temporarily lose lock on the satellite. Metal
buildings, chain-link fences, and bodies of water are all
good reectors that can make a base station less reliable.
Take care to place your base station receiver far away
from strong reectors for reliable base station operation.
A base station should have a continuous 12V power
source such as an AC/DC converter to power the base
station. A battery back-up is recommended to keep the
base station running in the case of power outages for
dependable operation.
NOTE: The AC/DC converter is not supplied
by John Deere.

A—Horizontal Precision (m) B—Maximum PDOP Value
The Position Dilution of Precision (PDOP) is likely one
of the most critical GPS AutoTrac values to monitor.
As the PDOP value increases, both the horizontal and
vertical precision (guidance accuracy) of your data points
decreases.
To help illustrate this relationship, please review the
graph, which plots the PDOP value against the horizontal
precision points collected on and around the University of
Montana campus. Ten locations were collected to serve
as ground control points to register an April 4, 1999 aerial
photograph of the University area. You can see that
as the PDOP value climbs from a minimum of 1.15 to a
maximum of approximately 4.5, the horizontal precision
and accuracy decreases from about 1.15 meters to about
1.9 meters. PDOP values below 7 are generally required
to collect data at a 1 meter accuracy range (as determined
by the PDOP mask set on your data logger) and any value
below 3.5 is considered in-range for AutoTrac applications.

GOOD
Keep in mind that PDOP (Position Dilution of Precision)
is the measure of the geometrical strength of the GPS
satellite conguration. As a general rule, any PDOP value
below 3.5 is acceptable to use while operating AutoTrac
but, the lower the number, the more precise the steering
accuracy will be.

During vehicle operation, the PDOP can be viewed
under the StarFire information pages in both the Original
