RTK Base Station Setup
SH20560,0000119 1907DEC091/1
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.
Performance of the RTK correction is related to the
operating distance from the base station. When operating
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.
