ZHONGKEWEI ATGM332D-6N-74

The ATGM332D-6N series module is the general designation for a family of high-performance GNSS all-constellation positioning and navigation modules measuring 12.2×16mm. Based on ZhongKe Micro's sixth-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, GLONASS, and others. It can simultaneously receive satellite signals from all of the above navigation systems and achieve combined positioning, navigation, and timing. Supporting simultaneous reception of signals from all-constellation satellites, the module leverages proprietary rapid satellite acquisition technology to quickly receive a large number of visible satellite signals, enabling fast and accurate positioning. This significantly improves positioning 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, enabling rapid detection and suppression of RF interference. Employing 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. This module series is applicable to vehicle navigation, wearable devices, mobile phones, IoT devices, UAVs, and other application domains.
