John Deere’s StarFire 7500 receiver, paired with the SF-RTK satellite correction signal, delivers RTK-like accuracy and long-term repeatability—up to 2.5 cm (1 in.) horizontal precision—without the need for additional hardware or dealer base station access. This next-generation receiver offers faster pull-in times (up to 73 percent quicker than SF3), improved signal tracking through multi-constellation support (GPS, GLONASS, BeiDou, Galileo), and seamless performance even near tree lines or field obstructions. SF-RTK simplifies the customer experience by eliminating the complexity of switching base stations between fields, a common challenge with traditional Radio RTK systems.

What does SF-RTK do?

The StarFire 7500 utilizes four GNSS satellite constellations, which are corrected through John Deere’s StarFire network to provide sub-inch horizontal accuracy. This provides customer’s our highest accuracy level, along with long-term repeatability (where applicable) to enable advanced guidance features and the confidence that guidance lines and boundaries won't shift from year to year.

Why should customers use SF-RTK?

Customers are continually looking for simplified solutions that deliver the value needed for their operation. SF-RTK offers a lower cost of entry for customers compared to Radio RTK, making this solution an easy decision for customers looking to use a high precision correction signal. Why pay for additional hardware, permanent licenses and base station access fees when SF-RTK only requires a yearly license to operate on your StarFire 7000 or StarFire 7500 receiver.
