RTK (Real Time Kinematic)

RTK (Real Time Kinematic) is the use of fixed position base stations to enhance the accuracy of GPS systems by transmitting signals that correct positioning errors caused by the Earth’s atmosphere.

Fixed RTK base stations, as the name suggests, have a permanent position which never changes. This position is transmitted to the Tractor which can then correct its own position, which constantly varies, and align it to the base station. Therefore creating the most accurate position.

Base Stations

As the base stations never move it is possible to create fixed traffic lines in fields as the recorded GPS positions are repeatable and will always be in the same place.

As the range of an individual base station is limited our base stations are placed strategically so that the coverage overlaps. This builds redundancy into the systems and means that the systems is always being used within healthy operating parameters and not at extremes.

RTKF Net use a mixture of Radio base stations, that are specific to Trimble receivers, and networked base stations that use 4g and internet based cloud servers to transmit the signal. Radio bases are available through East Anglia and Lincolnshire.

Our History

RTKF Net was founded by a group of farmers based in South Cambridgeshire who have joined together to make a robust and affordable GPS RTK network.

Initially its principal ideals were to create one of the first RTK networks that was cost effective and most importantly did not limit the individual farmer to small areas of coverage; ensuring that as far as is possible every field has reliable coverage the whole time. This was originally achieved using a network of radio base stations through out East Anglia.

As RTKF Net grew it was clear that we needed to embrace new technologies, it was also clear that there was a need for affordable RTK coverage across the rest of England. In order to achieve this we have installed a network of base stations that deliver the signal via the internet and SIM cards to any make of GPS equipment. This system perfectly compliments the radio network and allows us to provide a more efficient service with remote support handling and monitoring.

RTKF national coverage


The range of an individual RTK Base station is limited. This is due to the fact that both the vehicle and base station need to be receiving positioning information from the same satellites in order for the process to work. As this range is often too small for farms that are spread over a larger area or indeed contractors working on many different farms, RTKF Net has installed a network of base stations that allows for much wider coverage.
