Test Equipment with Fiber Optic Data Bus and Laser Gyro Strapdown System Ltn-90 for the Helicopter BO-105

摘要

The measuring instruments with a MUDAS interface system for flight-testing navigation systems in the helicopter BO-105 are described. The bit-serial bus was constructed using fiber optics. The reference data from a laser gyro strapdown navigation system were corrected by application of optimal filter techniques and external measurements. The results of testing the overall system are presented, and the accuracy of the development of the reference trajectory compared with the data of the laser radar PATS is explained with reference to a test flight.
