RTK Base Station Setup
OUO6050,0000EDA –19–08NOV07–1/4
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.

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 iTC”
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.
