The RACELOGIC DGNSS Base Station is designed to improve positional accuracy of VBOX units and other compatible GPS/ GLONASS systems by calculating and transmitting differential correction data.
By programming the Base Station with a known position, it is able to accurately monitor the difference between its programmed position and the position that it is receiving via GPS/GLONASS.
The difference is then transmitted via radio to allow a remote GPS system to correct its position.
The differential correction message can be broadcasted in RTCM, CMR or proprietary RTK formats using an internal or mast mounted radio modem transmitter.
Depending on the type of Base Station and roving unit used, position accuracies of up to 2cm 95% CEP are available.
