GNSS BASE STATION
POLYNAV 2000B
The PolyNav 2000B GNSS Base Station is a ruggedized dual-frequency (L1/L2) multi-constellation GNSS (GPS, QZSS, GLONASS, Beidou, Galileo) reference station which can be easily configured as a local base station to broadcast real-time RTCM corrections for any RTK-capable rover systems. User-friendly control software is available to set up a base station quickly by either connecting to the rover through a local radio link or NTRIP caster (network RTK). The system can also record all tracked dual-frequency multi-constellation measurements for post-processing.
