Differential Base Station(RLVBBS5)

The RACELOGIC DGNSS RTK 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 toaccurately 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, CMRor proprietary RTK formats using an internal or mast mounted radio
modem transmitter.
Depending on the type of roving unit used, position accuracies of up to2 cm* are available.

Features•••••

Survey grade GPS/GLONASS receiver with L1/ L2
Up to 2 cm* accuracy
RTCM, CMR, RTCMV3 or proprietary outputs
25-position memory to store and recall different
reference locations
Optional integral or mast mount radiotransmitters with range of up to 10 km (approx.
6.2 miles line of sight) and 2 km in built-up area••••Self-survey mode
Up to 18 hrs built-in battery life (dependingon radios in use) or external power
Rugged IP64 (splash proof) enclosure
Compatible with wide range of radios tosuit location and range requirements* 95 % CEP (Circle Error Probable) means 95 % of the time the position readings will fall within a circle of the stated radius.

Communication with external units is carried out via radio. TheBase Station is designed to work with a variety of different
radios, to suit different requirements.
RACELOGIC have a number of radio sets available, allowing youto select the most suitable frequency and range for your region.
See the Radios info sheet or contact RACELOGIC to find outmore.

InputsPower can be obtained either from the internal battery supply or from an externalsource via a front panel (using the supplied mains power supply, or via an external
waterproofed connector from a suitable 8-30 V DC supply).

PowerGPS/ GLONASS Antenna

Connects to the Base Station via screw-on TNC connectors and must be placed in aposition away from any other obstacles that could cause satellite signals to be
blocked or reflected. Wherever possible, place the antenna and tripod (needs to beordered separately) at the highest available spot to ensure the best un-affectedsatellite reception.

Outputs
Radio Antenna

None included. Variety of radios available depending on country and range
requirements: please see radios info sheet or contact RACELOGIC.
