ZHONGKEWEI ATGM332D-F8N22

The ATGM332D-F8N series module is a high-performance single BeiDou multi-frequency positioning and navigation module measuring 12.2×16mm. This product series supports BeiDou-2 and BeiDou-3 B11, B1C, B21, B31, B2a, and B2b frequency band signals. The module employs proprietary rapid satellite acquisition technology to quickly receive signals from a large number of visible satellites, enabling fast and accurate positioning while significantly improving positioning performance in complex environments. Integrated with a high-performance embedded CPU, the maximum position update rate reaches up to 20Hz. The module incorporates a proprietary anti-interference hardware acceleration circuit for rapid detection and suppression of RF interference, along with a high-precision timing engine offering timing accuracy better than 10ns. Utilizing a new integrated navigation SOC single-chip technology, it meets the requirements of high-precision positioning and timing applications, featuring high integration, high performance, low power consumption, and compact size.
