Full System Full frequency Point High Precision Positioning Board
ER-GNSS-B02 is a new generation of compact high-precision positioning board basedon NebulasIV RF baseband integrated chip, which supports full-frequency high-precision positioning of the whole system. Supports BDS B1I/B2I/B3I/B1C/B2a/B2b*, GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, QZSS L1/L2/L5, SBAS and other satellite signals.
The ER-GNSS-B02 comes in a small classic size, compatible with the previous generation of mainstream boards. Mainly for surveying and mapping, lawnmower, precision agriculture and other applications.
