Flight Testing of a Strapdown System. Results of a Special Flight Test

摘要

Instruments and data evaluation used in flight testing of the modular strapdown system (MSS) are described. Reference data, based on an inertial navigation system and optimal smoothing techniques, are shown for a flight test on the HFB 320 aircraft. The MSS flight tests were limited to the navigation part. The results show position errors of 10 km/hr maximum, speed errors of 8 m/sec maximum, elevation angle errors 0.4, and course error drift of 0.4/hr.
