Introduction

The ATGM332D-6S series modules are automotive dead reckoning modules that integrate a GNSS receiver and a 6-axis inertial sensor, capable of providing continuous high-precision 3D positioning for moving vehicles in GNSS-denied environments such as tunnels, underground parking garages, and underpasses. This product series is based on a 6th-generation multi-system GNSS SoC, supporting multiple satellite navigation systems including BeiDou-2, BeiDou-3, GALILEO, GPS, QZSS, SBAS, and GLONASS, enabling simultaneous signal reception and combined PNT. The module supports full-constellation satellite signal reception and employs a proprietary rapid satellite acquisition technology to quickly capture a large number of visible satellites, achieving fast and accurate positioning with significantly improved performance in challenging environments such as urban canyons. Featuring an integrated high-performance embedded CPU, the module supports a maximum position update rate of 10Hz, making it suitable for high-dynamic applications sensitive to positioning latency. An integrated proprietary anti-jamming hardware acceleration circuit enables rapid detection and suppression of RF interference. This series of modules offers the advantages of high integration, high performance, low power consumption, and low cost.
