Introduction

Beidou GNSS Three-star Seven-frequency Positioning Board

ER-PB-03 Beidou GNSS Three-star Seven-frequency Positioning Board is a set of high-performance three star 7-frequency RTK positioning receivers that support BDS B1/B2/B3, GPS L1/L2, GLONASS G1/G2 signal reception.

It supports single-system working mode and multi-system joint solution. The board has carrier phase RTK function, providing high positioning accuracy and variable data update rate. Support 100km long baseline RTK, also supports SBAS mode, or stand-alone can automatically switch to SBAS mode. The board uses a unique COAST patented technology to obtain accurate satellite signals no matter when and where.
