ZHONGKEWEI ATGM336H-6N-74

The ATGM336H-6N series module is the collective designation for a high-performance GNSS all-constellation positioning and navigation module series measuring 10.1×9.7mm. Based on ZHONGKEWEI's 6th-generation multi-system GNSS SOC single-chip AT6668, it supports multiple satellite navigation systems — including BeiDou-2 and BeiDou-3 (B1I and B1C), GALILEO, GPS/QZSS/SBAS, and GLONASS — enabling simultaneous reception of satellite signals for combined positioning, navigation, and timing. Supporting simultaneous reception of signals from all constellation systems, the module leverages proprietary rapid satellite acquisition technology to quickly receive a large number of visible satellite signals, achieving fast and accurate positioning with significantly improved performance in challenging environments such as urban canyons. An integrated high-performance embedded CPU supports 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 is also integrated for rapid detection and suppression of RF interference. Employing an all-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. This module series is applicable to automotive navigation, wearable devices, mobile phones, IoT devices, UAVs, and other application domains.
