The instruments and data evaluation procedure for the flight testing of the modular strapdown system are described. Reference data based on an inertial navigation system and optimal smoothing techniques are presented for a test flight of an HFB 320 aircraft. Overall position error is 10 km/hr maximum. Maximum velocity deviation is 8 m/sec; attitude errors are 0.4 deg; heading error drift is 0.4 deg/hr. Alignment error in heading cannot be given since the system was aligned with the aid of the azimuth of the LN3-2A system throughout the test flight series. The MSS system operated without major faults, apart from the switch-overs of the gyroscope measuring ranges, which produce large errors in the heading and attitude during stationary runs.
