The main chip solution adopted by the GPS part of the EC-01G module is AT6558R. This chip is a high-performance BDS/GNSS multi-mode satellite navigation receiver SoC single chip, on-chip integrated radio frequency front end, digital baseband processor, 32-bit RISC CPU, power management function. The chip supports a variety of satellite navigation systems, including China's Beidou satellite navigation system BDS, the United States' GPS, and Russia's GLONASS, and can realize multi-system joint positioning.
It has the following characteristics (GPS):
- Support BDS/GPS/GLONASS multi-system joint positioning and single-system independent positioning.
- With active antenna detection and protection.
- RTC and backup circuit power supply can be as low as 1.4V
- BDS/GPS dual-mode continuous operation.
