Gravity: GNSS GPS BeiDou Receiver Module - I2C&UART
The Gravity: GNSS GPS BeiDou Receiver Module is a powerful, multi-system satellite positioning module supporting GPS, BeiDou, GLONASS, and QZSS. It enables highly accurate, stable, and fast positioning in a variety of outdoor environments, making it ideal for vehicle navigation, UAV flight control, weather stations, and smart farming.
What is GNSS?
GNSS (Global Navigation Satellite System) refers to global satellite constellations that allow receivers to determine precise geographic location by calculating satellite signal propagation time. This module supports joint multi-system positioning, offering improved signal coverage and reliability compared to single GPS modules.
