Low Cost High Quality GPS Module Atgm332D-5n

1.   Function Description 

1.1    Summary

ATGM332D-5N series module is the genetic name of BDS/GNSS GPS navigation module series with good performance and 12X16 size. These series are based upon GNSS SOC single chip--AT6558, they support multiple systems such as BDS of China, GPS of the US, GLONASS of Russia, GALILEO of the EU, QZSS of Japan and Satellite augmentation system SBAS(WAAS, EGNOS, GAGAN, MSAS). AT6558 is the real meaning multimode satellite navigation module, which contains 32 tracking channels and accept 6 GNSS signals of satellite navigation systems, it an also realize the joint positioning ,navigation and timing. This series module with the advantage of high sensitivity, low-power consumption and low cost is suitable for car navigation, handheld positioning, wearable device and can directly take place of U-blox NEO series module.
