Producers can select between two real-time kinematic (RTK) solutions: John Deere Radio RTK, which transmits the RTK corrections by radio, or John Deere Mobile RTK, which transmits the RTK corrections through an existing cellular network.
Each solution requires the John Deere RTK activation. Both methods of RTK corrections offer fast start-up times, with a StarFire™ receiver, which will achieve 100 percent accuracy in less than 1 minute.
This solution utilizes a local, ground-based reference station that transmits corrections to a StarFire receiver on a machine through RTK radios. Nearly all satellite drift is eliminated because of the proximity of the base station to the machine. A direct line of sight between the base station and the machine receiver is required for the base-station signal to reach the machine.
John Deere Radio RTK requires:
This solution utilizes RTK correction data offered through a third-party provider. A machine equipped with a John Deere Mobile RTK Modem can connect through the third-party cellular network and differential correction network to get repeatable RTK correction data wherever the provider’s cellular correction is available.

**Mobile RTK Access only needed for use of third party Mobile RTK Correction networks. The John Deere Mobile RTK Signal subscription always included a Mobile RTK Access license.

With many real-time kinematic (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 or in areas with limited cellular coverage. That is not the case when using RTK with John Deere, thanks to RTK Extend capability.
John Deere RTK Extend provides RTK performance even when temporarily losing the radio/mobile correction signal.
RTK performance is maintained for StarFire 6000:
RTK performance is maintained for StarFire 3000:
The StarFire Receiver automatically transitions to RTK Extend when line of sight to the base station is lost or the cellular coverage is limited. If within 14 days/15 minutes the receiver has not received an RTK signal the receiver will end the RTK Extend mode. In that unlikely case, SF1 is still available but needs to be manually selected by deactivating the RTK mode.

When using StarFire 3000 Receivers, the rover receiver automatically switches to the SF2 signal when RTK Extend expires. This allows operators to take advantage of +/- 5-cm (2-in.) SF2 accuracy for a maximum 14 days along tree lines or hilly terrain. The machine transitions from RTK to RTK Extend, to SF2, and back to RTK without disengaging AutoTrac. This benefit does not require a SF2 license.
