BeiDou GNSS module A32s

QZSSGALILEOSBAS

Overview
A32s module is a GNSS high-precision dual-antenna module suitable for various user groups such as UAV, precision agriculture, machine control, robotics and autonomous applications. It is a single-board solution for precise position and heading. The product delivers multiconstellation RTK baselines between two connected antennas and to a remote base station. It integrates SpatiX SuperRTKTM, SmartPPP® and Heading technology and can provide positioning and direction information to users within a centimeter range.
