ZHONGKEWEI ATGM336H-7N-22

The ATGM336H-7N BeiDou positioning series module is a high-performance BeiDou single-frequency positioning and navigation module in a 10.1×9.7mm form factor. This series is based on ZHONGKEWEI's next-generation SOC BeiDou chip AT6850B, supporting BeiDou-2 and BeiDou-3 B1I and B1C frequency band signals. Leveraging proprietary fast satellite acquisition technology, the module can rapidly receive signals from a large number of visible satellites, enabling fast and accurate positioning with significantly improved performance in challenging environments such as urban canyons. An integrated high-performance embedded CPU enables a maximum position update rate of 10Hz, making it suitable for high-dynamic applications sensitive to positioning latency. A proprietary anti-jamming hardware acceleration circuit provides rapid detection and suppression of RF interference. Built on a new navigation-integrated SOC single-chip architecture, the module meets the demands of high-precision positioning and high-precision timing applications, while offering high integration, high performance, low power consumption, and a compact form factor.
