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

Rugged Splash Proof Case
- GNSS Antenna
Connects to the Base Station via screw-on TNC connectors and must be placed in a position away from any other obstacles that could cause satellite signals to be blocked or reflected. Wherever possible, place the GNSS antenna and tripod (needs to be ordered separately) at the highest available spot to ensure the best un-affected satellite reception.
Power can be obtained either from the internal battery supply or from an external source via a front panel (using the supplied mains power supply, or via an external waterproofed connector from a suitable 8-30 V DC supply).
- Radio Antenna
None included. Variety of radios available depending on country and range requirements. Please see radios info sheet or contact RACELOGIC.
Front Panel Interface
Indicates the operating status of the Base Station.
- RS232 Serial Interface
Used for updating the operating firmware of the Base Station using a PC or porting to the GPS engine or radio modem for update of firmware or manual configuration changes.
A power input connector for charging the Base Station internal battery using the supplied mains adaptor.
