Introduction

Small Size High Precision Positioning Board

ER-PB-07 Small Size High PrecisionPositioning Board is based on the "Tianqin" second generation baseband chip, it can receive GNSS signals from all constellation and full frequency points, fully support beidou 3 satellite signals, update support Galileo, QZSS and other new signals, and support “China precision”.

The product also supports single-system working mode and multi-system joint solution mode, board with carrier phase RTK function, supports long baseline RTK and fast initialization. In addition, it has a built-in 9-axis IMU, supports vehicle integrated navigation, and integrates positioning functions such as L-Band satellite-based enhancement, RTK, SBAS, etc., and has the characteristics of small size and easy integration.
