Tractor working in a field using network RTK corrections
Base-free RTK · UK & Europe

RTK corrections without an on-farm base station

Already have one RTK-enabled tractor? Connect it to accurate, repeatable NTRIP corrections across the UK and supported European areas - without buying, installing or maintaining a farm base.

Annual licence £400 + VAT

Per tractor, per year. Limited to one concurrent tractor connection per licence.

Optional mobile data £90 + VAT

Multi-network SIM per tractor, per year, for reliable NTRIP connectivity while working.

Installation No farm base

Use the RTK hardware already on the tractor, provided it is unlocked and NTRIP capable.

Built for a single RTK tractor - and work beyond one farm

This option is intended for farms and contractors that do not need their own local base station. It is particularly useful where only one tractor needs RTK, where the machine travels between farms, or where UK and European coverage matters more than a fixed local base.

Full UK-wide service

Use one set of NTRIP credentials across supported UK coverage.

European working

Supported European areas are available under the same service, subject to a coverage check.

Up to 10 mm accuracy

Centimetre-level RTK performance depends on the receiver, antenna, sky view, calibration and local conditions.

5-year repeatability

Designed for returning to the same guidance lines over multiple seasons when datum, calibration and machine setup remain consistent.

All service fees included

The annual correction licence includes administration, network running costs and service fees.

Same standard NTRIP RTK

Corrections are delivered over the internet to compatible agricultural RTK receivers.

How base-free RTK works

The base stations already exist within the partner network. Your tractor sends its approximate position to the NTRIP service and receives the appropriate RTCM correction stream over mobile data.

Check the tractor

Tell us the tractor, display and receiver models. We confirm the required RTK unlocks, NTRIP capability and likely compatibility.

Test coverage

We arrange a free trial so you can confirm RTK FIX, accuracy and repeatability on the actual machine and working area.

Activate the licence

We provide and support the NTRIP connection details. Add the optional multi-network SIM where a suitable data connection is not already fitted.

What you need

Required on the tractor

  • An RTK-capable GNSS receiver and suitable antenna.
  • The correct RTK and NTRIP unlocks or activations.
  • A display, modem or gateway able to enter NTRIP host, port, mountpoint and login details.
  • A clear view of the sky and a correctly calibrated steering system.

Internet connection

NTRIP corrections require mobile data while the tractor is working. You can use an existing suitable connection or add our multi-network agricultural SIM.

Optional multi-network SIM: £90 + VAT per tractor per year.

Base-free licence or your own farm base?

The cheaper option depends on how many machines need RTK and where they work. A single travelling tractor usually suits the base-free licence. Several RTK machines working mainly around one farm often suit the farm base package.

Compatible with major tractor RTK systems

The service is not locked to one tractor brand. It works with many systems that can receive standard NTRIP RTK corrections. Compatibility depends on the receiver, display, software version and unlocks fitted to the machine.

Test it before committing

A free trial is available to confirm that your tractor connects, reaches RTK FIX and performs correctly in the areas where you intend to work.

Base-free RTK questions

Do I need to install a base station?

No. The tractor receives corrections from the reference-station network over NTRIP. There is no RTK base unit or antenna to install on the farm.

How much does it cost?

The licence is £400 + VAT per tractor per year. It includes the correction service, administration, network running costs and associated service fees.

Can one licence be shared between tractors?

No. Each licence is limited to one tractor. A second tractor requires a second licence. Farms with several RTK machines should compare this with the farm RTK base package.

Is a SIM card included?

No. Use an existing suitable data connection or add an optional RTK Solutions multi-network SIM for £90 + VAT per tractor per year.

Will it work anywhere in the UK and Europe?

The service provides UK-wide and supported European coverage. Coverage can still vary with the reference-station network and local mobile signal, so RTK Solutions checks the intended working area before activation and provides a trial.

Does “up to 10 mm” mean it is always accurate to 10 mm?

No. That is the best expected horizontal RTK performance under suitable conditions. Real performance depends on the tractor receiver, antenna, calibration, satellite view, correction age, local interference and field environment.

What does 5-year repeatability mean?

It means the system is designed to let you return to the same stored guidance lines over multiple seasons. Reliable long-term repeatability requires consistent datum settings, receiver configuration, machine calibration and saved line data.

Who sets it up?

RTK Solutions confirms compatibility, supplies the NTRIP details, assists with setup and provides the ongoing customer support. Complex network issues are handled with our RTK data network partner.

Ask Sales to check your tractor and coverage

Send the tractor brand, receiver/display model, current unlocks and the UK or European areas where it will work.

Prices shown exclude VAT. Accuracy, RTK FIX availability and repeatability depend on compatible equipment, correct setup, satellite visibility, mobile data availability and local conditions. European coverage is confirmed for the intended working area before activation.
