5N71 Satellite Positioning Module

ATGM336H-5N series modules are the general name for a series of small-sized, high-performance BDS/GNSS full-constellation positioning and navigation modules. This series of module products are based on Zhongke Micro's fourth-generation low-power GNSS SOC single chip - AT6558, which supports a variety of satellite navigation systems, including China's BDS (Beidou Satellite Navigation System), the United States' GPS, Russia's GLONASS, and the European Union GALILEO, Japan's QZSS and satellite augmentation systems SBAS (WAAS, EGNOS, GAGAN, MSAS). AT6558 is a true six-in-one multi-mode satellite navigation and positioning chip, including 32 tracking channels, which can receive GNSS signals from six satellite navigation systems at the same time, and achieve joint positioning, navigation and timing. ATGM336H-5N This series of modules has the advantages of high sensitivity, low power consumption, and low cost. It is suitable for vehicle navigation, handheld positioning, and wearable devices, and can directly replace Ublox MAX series modules.

Output protocol: ATGM332D-5N series modules use UART as the main output channel and output according to the protocol format of NMEA0183. For specific information, please refer to the "CASIC Multi-mode Satellite Navigation Receiver Protocol Specification".
