    Introduction

    Multi-frequency High-precision Full System Positioning Board

    ER-GNSS-B04 is a new generation of compact high-precision positioning board based on NebulasIV RF baseband integrated chip, which supports full-frequency high-precision positioning of the whole system. Supports BDS B1I/B2I/B3I, GPS L1/L2/L5, GLONASS L1/L2, and Galileo E1/E5a/E5b, QZSS L1/L2/L5, SBAS and other satellite signals. The ER-GNSS-B04 comes in a small classic size and is compatible with the previous generation of mainstream boards. Mainly for UAV, lawn mower, handheld equipment, high precision GIS and other application fields.
