ATGM336H Dual-mode GPS+BDS Satellite Positioning Module

ATGM336H series modules are a general term for a series of small-sized, high-performance BDS/GNSS full-constellation positioning and navigation modules. This series of module products are all based on the fourth-generation low-power GNSS SOC single chip of Zhongkewei—AT6558, which supports a variety of satellite navigation systems, including China's BDS (Beidou Satellite Navigation System), the United States' GPS, Russia's GLONASS, the European Union's 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, containing 32 tracking channels, which can simultaneously receive GNSS signals from six satellite navigation systems and realize joint positioning, navigation and timing. ATGM336H series modules have the advantages of high sensitivity, low power consumption and low cost, and are suitable for vehicle navigation, handheld positioning, and wearable devices, and can directly replace Ublox MAX series modules.

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