The RACELOGIC DGNSS RTK Base Station is designed to improve positional accuracy of VBOX units and other compatible GNSS 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 known position and the position that it is calculating from GNSS satellite signals.
The difference is then transmitted via radio to allow a remote GNSS system to correct its position.
The differential correction message can be broadcasted in RTCM v2, RTCM v3, RTCM v3.2 MSM4 (VBBS6 only), RTCM v3.2 MSM7 (VBBS6 only), CMR (VBBS5 only), or proprietary RTK formats using an internal or mast mounted radio modem transmitter.
Depending on the type of roving unit used, position accuracies of up to 2 cm 95% CEP are available.
The table below lists the VBOX and Base Station combinations required to achieve a specific accuracies. For a more detailed overview, including legacy products, please refer to: https://racelogic.support
