ATGM336H Module GPS Beidou dual mode module flight control with EEPROM

The ATGM336H-5N series module is a general term for the small-size high-performance BDS/GNSS constellation positioning navigation module series. The series of modules are based on the fourth generation of low-power GNSS SOC single chip – AT6558, supporting a variety of satellite navigation systems, including China’s BDS (Beidou satellite navigation system), the United States’ GPS, Russia’s GLONASS, the EU’s GALILEO, Japan’s QZSS and satellite augmentation system SBAS (WAAS, EGNOS, GAGAN, MSAS). The AT6558 is a true 6-in-1 multi-mode satellite navigation positioning chip that includes 32 tracking channels that can simultaneously receive GNSS signals from six satellite navigation systems and enable joint positioning, navigation and timing. ATGM336H-5N series modules have the advantages of high sensitivity, low power consumption and low cost. They are suitable for in-vehicle navigation, handheld positioning and wearable devices, and can directly replace Ublox MAX series modules.
