Broaden RTK availability with repeaters
RTK repeaters are radios that can be used to improve base station signal coverage around obstacles, such as trees or rolling terrain. The purpose of the RTK Repeater is to receive the correction signal coming from the base station and then transmit that correction signal.
More than one repeater can be used with one base station, but the repeater cannot receive signal from each other in a daisy-chain configuration. In order to operate, a repeater must be connected to a 12-V power source.
RTK Extend™ allows operator to keep running AutoTrac™
With many RTK solutions, automatic guidance simply stops working if trees or rolling terrain interfere with the line of sight between the base station and the machine. That is not the case when using RTK with John Deere, thanks to RTK Extend capability.
RTK Extend allows AutoTrac to keep functioning for up to 15 minutes with RTK accuracy without line-of-sight to the base station.
RTK and StarFire 3000 Receiver
When using StarFire 3000 Receivers, the machine receiver automatically goes to the SF2 signal when RTK Extend expires. This allows operators to take advantage +/- 5-cm (2-in.) accuracy along tree lines or hilly terrain. The availability of SF2 provides RTK users with the best available accuracy by lessening the impact of any given field condition.
Provides repeatable accuracy
John Deere RTK
It utilises a local, ground-based reference station that transmits the high-accuracy +/- 2.5 cm (1 in.) corrections to a machine StarFire receiver via RTK Radios.
Because of the proximity of the base station to the machine, nearly all satellite drift is eliminated, and the position is highly repeatable. In order for the base-station signal to reach the machine, a direct line of sight is required.
