GPS module information

The GPS module is a high-performance BDS/GNSS positioning and navigation module based on ATGM336H-5N. The module supports a variety of satellite navigation systems, including all the satellites of China's Beidou-2 and Beidou-3, the United States' GPS, Russia's GLONASS, and Japan's QZSS. It can simultaneously receive the satellite signals of the above satellite navigation systems, and realize joint positioning and navigation. And timing, the module has the advantages of high sensitivity, low power consumption, low cost, etc., suitable for vehicle navigation, handheld positioning, wearable devices.
