RACELOGIC DGNSS BASE STATIONS

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.

  • Survey grade GPS or GPS/GLONASS receiver
  • Integral 9Ah battery supply with fast charger
  • LCD readout for status and configuration
  • Optional integral or mast mount radio transmitters with range of up to 10km (line of sight) and 2km in a built up area
  • Compatible with wide range of radios to suit location and range requirements
  • Up to 2cm accuracy (option 2)
  • RTCM, CMR, RTCMV3 or proprietary outputs
  • 25-position memory to store and recall different reference locations
  • Self survey mode
  • Up to 18hr battery life (depending on radios in use) or external power
  • Rugged IP64 (splash proof) enclosure

There are two Base Station options available.

Option 1 - DGNSS DGPS Base Station (RLVBBS4)

  • GPS Only
  • Correction message in RTCM type 1 & 3, and Racelogic proprietary (20cm)

Option 2 - DGNSS RTK Base Station (RLVBBS4RG)

  • GPS + GLONASS + RTK
  • Correction message in RTCM type 1 & 3, CMR, RTCMV3 and Racelogic proprietary (2cm)

The table below lists the VBOX and Base Station combinations which are required for specific accuracies.
