An identification algorithm for systematic measurement errors of air velocity and the aerodynamic angles of a flight vehicle in the course of flight testing, which uses high precision velocity measurements performed by a satellite navigation system, is proposed. A specific feature of the considered method is that a wide set of flight maneuvers, along with the specialized test regimes used in the practice of flight testing, can be used for solving the problem. The performance of the method and the legitimacy of the assumptions made are proved by processing large volumes of the experimental data obtained in the course of flight testing.
