RTK coverage in Great Torrington.
Great Torrington is 30 km north-east of our base on the Atlantic Highway at Bude. At that baseline a multi-band receiver should hold about 38 mm horizontally and 45 mm vertically. At the edge. A fix is achievable but takes longer to converge and is more sensitive to atmospheric conditions. Fine for guidance; check the numbers before survey work.
The numbers for Great Torrington.
Computed from coordinates. The only thing that will change them is where you actually stand relative to the base.
Bideford, by 27 km
The community station at Bideford is closer to Great Torrington than we are, and a shorter baseline is a better baseline. A community station on the public RTK2Go caster. Useful, but with no service guarantee and an unverified absolute position. Use it for guidance; for survey work where the absolute position matters, talk to us.

Commissioning autumn 2026
Corrections are delivered over NTRIP, which needs a data connection at your receiver. Register below and we email the caster address and mountpoint the day it goes live, with notes for whatever receiver you run. If you have no mobile signal in the field, say so: that is what decides whether we add a UHF radio link.
Your receiver decides
AgOpenGPS, CNH and Topcon connect directly. John Deere StarFire needs an RTK activation and usually an external modem. Trimble's free tier will not accept a third-party caster at all. Tell us what you run and we will tell you before you spend anything.
