DFRobot GPS + BDS BeiDou Dual Module

This small positioning and navigation module from DFRobot is based on the AT6558 (a six-in-one multimode satellite navigation and positioning chip). It can provide real-time location information and supports a variety of satellite navigation systems, including up to 32 tracking channels. In addition, the module can receive GNSS signals from six different satellite navigation systems at the same time, including the Chinese BDS, the American GPS, the Russian GLONASS, the European GALILEO, the Japanese QZSS, and the SBAS Satellite Augmentation System (WAAS, EGNOS, GAGAN MSAS), to achieve accurate positioning and timing. The error of positioning accuracy is below 3m, which equates to the accuracy of a smartphone. The module's power consumption is less than 0.1W and can thus operate continuously for a long time with a small power supply. Due to the small size of the module, it can be built into various types of drones and smart cars.

In serial output mode, the AT6558 is compatible with various motherboards equipped with a serial output:

Arduino
Raspberry Pi
STM32
ESP32
EP8266
