The article presents the flight data analisys of GPS/GLONASS aircraft velocity measurements errors which appear while the aircraft manoevering. Algorithms for velocity measurements errors estimation and correction are proposed. These algorithms are based on the joint processing of satellite data and the data of other avionics systems, that is inertial navigation system and flight control system. The effect of GPS/GLONASS antenna shift from the aircraft mass center is also estimated. All the presented results are verified through the processing of flight tests data.
