The 7Semi LG290P GNSS RTK Modem is a high-precision, multi-band positioning solution designed for centimeter-level accuracy. It supports GPS, GLONASS, Galileo, BeiDou, QZSS, and NavIC, along with multi-band reception and RTK technology for reliable positioning. With Rover and Base operation and fast position updates, it is ideal for surveying, precision agriculture, robotics, mapping, and automation.
RTK Rover: Receives RTCM correction data from a reference base station or correction service to achieve centimeter-level positioning.
RTK Base: Operates as a fixed reference station and provides RTCM correction data to rover receivers for real-time centimeter-level positioning.
Note-: I2C is not available on this device , this feature is currently under devlopment
