ATGM336H-5N series module is the general name of the small size high performance BDS/GNSS full constellation positioning and navigation module series. This series of module products are based on Zhongke Micro's fourth-generation low-power GNSS SOC single-chip-AT6558. Supports a variety of satellite navigation systems, including China's BDS (Beidou Satellite Navigation System), US GPS, Russia's GLONASS, EU'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, including 32 channels, can receive GNSS signals of six satellite navigation systems at the same time, and realize joint positioning, navigation and timing. This series of modules ATGM336H-5N has the advantages of high sensitivity, low power consumption, low cost, etc. It is suitable for car navigation, handheld positioning, 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 NMEA0183 protocol format.
