USR20-G Ground Base Station
Product Description
The USR20-G RTK Ground Base Station is a GNSS reference station installed on the ground with precisely known position. By real-time receiving satellite signals, it calculates ionospheric, tropospheric, orbital, and clock errors, and sends them to UAVs and other mobile terminals in the form of differential data, elevating them from ordinary meter-level positioning to centimeter-level high-precision positioning. This provides stable and reliable high-precision position reference for UAV aerial surveying, inspection, and autonomous operations.USR20-G RTK Ground Base Station is a GNSS reference station installed on the ground with precisely known position.
