UAV high-precision navigation system is a high-precision navigation and positioning solution used for UAV take-off and landing. It receives satellite signals, tracks satellite signals by airborne high-precision receiver, measures pseudo range between aircraft and satellite, calculates high-precision position and speed information by differential station from ground, and transmits the high precision results to inertial navigation system for integrated navigation.

Multi system RTK, medium and long baseline RTK, high update rate, differential calculation and mobile base station technology are applied in the system, centimeter level positioning can be achieved, and multi system joint calculation and multi system independent calculation can be realized.
