900 MHz RTK—Base Station Setup
Continued on next page JS56696,00007FF -19-15APR10-1/3
System Overview
The StarFire™ RTK system consists of a local base
station placed in a field 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.
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.
