DGNSS Base Station DGPS

| Datasheet || Manual || Application Note |

DGNSS-BasestationThe Racelogic Base Station is a complete differential correction system designed to provide local correction for improved GPS accuracy.

By programming the Base Station with a known GPS position, it is able to accurately monitor the difference between its programmed position and the position that it is receiving via GPS.

This difference is transmitted via radio to allow a remote GPS system to correct position.

When combined with a VBOX GPS system such as the VBOX 3i, the base station can provide positional accuracy of 40cm 95% CEP.

Featuring a high performance GPS engine and integrated radio transmitter, the Base Station can be powered from an external 12v source or from the built-in NiMh battery pack.

It is also supplied with separate radio modem to allow a mobile GPS system to receive the RTCM correction data.

Most VBOXs are compatible with this system. Simply place the Base Station in a fixed position, let it average the position for 5 minutes, and then you can measure position to a new level of accuracy. For an application note on the Base Station, please click on the link above.

The Base Stations is available with 40cm DGPS and 2cm RTK accuracy. The table below lists which VBOX/Base Station combination is required for specific accuracies.

RTK-V8The Base Station communicates with a VBOX via a radio telemetry link. Each Base Station has a radio module integrated inside, and comes with an external radio receiver for a VBOX which can work up to 10km away.

To get this full range, the Base Station has to be mounted as high as possible, on the top of a building, hill or tall mast and be in direct line of sight to the VBOX.

If the Base Station is placed on the side of the track, then you get around 1.5-2km range, which is enough for most test tracks.

Applications for the Base Station include track mapping, route plotting, road profiling and driver line analysis.
