## Description

Global Navigation Satellite Systems (GNSS) provide critical timing and positioning functions for device operations.

This Gravity: GNSS positioning module from DFRobot supports BeiDou, GPS, GLONASS and other multi-satellite systems. It is capable of quick delivery of position data like longitude, latitude, altitude and time. Compared with traditional single GPS positioning, the multi-system combination embraces higher precision and faster speed thanks to the increased number of visible and available satellites, which ensures stable and accurate performance even in complex urban environments.

With I2C and UART data outputs, this GNSS positioning module works well with main-controllers like Arduino, ESP32, and Raspberry Pi, which can be widely applied to outdoor positioning scenarios such as vehicle navigation, handheld positioning tracker, item tracking and weather station.
