Precision and value for your farm.
Our managed base combines precise local RTK positioning, fast startup and one renewal for multiple compatible machines.

SF3 figures are the cited StarFire 6000 ratings. Actual pull-in time varies; nine months is the published in-season specification, not an expiry. Positioning figures use different stated measures and do not guarantee implement placement.

Add 1 mm for each kilometre beyond 10 km, measured from the tractor to the physical reference base supplying its corrections.

Guaranteed farm-base range: 35 km; 45 km is a calculated example. Based on our stated specification with a properly configured RTK FIX in suitable conditions.
One farm base. Multiple tractors.
Includes the base, first-year network access, remote configuration and calibration. Renewals cover managed network access, monitoring and support for the farm base and multiple compatible machines.
Our corrections use internet-based NTRIP. Compatible RTK-enabled receivers and a suitable tractor data connection are required; receiver unlocks, modem/data and installation work are separate where needed. RTK Solutions supplies independent NTRIP RTK corrections, separate from John Deere’s SF3 service.
Only need one tractor? Base-Free RTK is £400 + VAT per tractor/year. The distance formula above is for the farm-base setup.
Move from SF3 to a farm-owned RTK reference.
Can I use my existing SF3 receiver?
We check the receiver, display, RTK activation, correction format and NTRIP connection before you buy. An SF3 licence alone does not make the receiver RTK-ready. See our John Deere compatibility guide.
Will my saved guidance lines stay aligned?
We check the existing reference before changing correction sources. Keep the antenna position, base coordinates, saved guidance and machine calibration consistent.
Is SF3 the same as SF-RTK?
No. This page compares SF3 on the cited StarFire 6000 setup. See our separate John Deere SF-RTK comparison.
