Introduction

Full System Full Frequency Point High Precision Positioning Directional Board

ER-GNSS-B01 is a new generation of compact high-precision positioning and orientation board based on NebulasIV RF baseband integrated chip, which supports full-frequency high-precision positioning and orientation of the whole system. Supports BDS B1I/B2I/B3I, GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, QZSS L1/L2/L5, SBAS and other satellite signals.The ER-GNSS-B01 comes in a small classic size and is compatible with the previous generation of mainstream boards. It is mainly used in UAV, precision agriculture, intelligent driving and other application fields.
