Introduction

The ATGM332D-F8S series module is a high-performance single BeiDou multi-frequency vehicle dead reckoning module measuring 12.2×16mm. The module integrates a BeiDou receiver and a 6-axis inertial sensor, providing continuous high-accuracy 3D positioning for moving vehicles in GNSS-denied environments such as tunnels, underground parking garages, and underpasses. Based on a next-generation SoC single BeiDou multi-frequency chip, the module supports BeiDou-2 and BeiDou-3 B1I, B1C, B2I, B3I, B2a, and B2b frequency band signals. The series employs proprietary rapid satellite acquisition technology to quickly receive signals from a large number of visible satellites, achieving fast and accurate positioning — with notably improved performance in challenging environments such as urban canyons. The module integrates a high-performance embedded CPU with a maximum position update rate of 20Hz. It also incorporates a proprietary anti-jamming hardware acceleration circuit capable of rapidly detecting and suppressing RF interference. The series offers the advantages of high integration, high performance, low power consumption, and low cost.
