Theory of Operation
NOTE: RTK Radio 450 systems are not compatible with
systems that operate outside of the 450 MHz
frequency range.
RTK Radio 450 system delivers 2.5 cm (1 in) repeatable
accuracy. RTK accuracy is expressed as an absolute
value (without + or -) because RTK performance is not
subject to satellite drift over time. RTK Radio 450 system
consists of a local base station that transmits high
accuracy corrections to a machine that has a StarFire
Receiver equipped with RTK Radio 450. An optional
amplier may be used to boost the base station signal.
Contact your John Deere dealer for availability and
certication in your country. Ensure that RTK radio on
machine has a direct line of sight with base station or
repeater to receive the RTK signal. Transmission power
and wavelength of RTK Radio 450 aids in transmission
through trees and foliage. It cannot penetrate through
earth in hilly terrains.
Performance of RTK correction is related to operating
distance from base station. RTK signal accuracy
degrades and takes longer to acquire when operating
beyond 20 km (12 mi).
