A Modular Universal Data Acquisition System 2 (MUDAS 2) equipped with an LTN-90 laser gyro strapdown navigation system and with a fiber optic data bus for transmission of ARINC-429 signals was developed for onboard testing of navigation systems. It was tested on a BO-105 helicopter during flights for applicability on helicopters and flexibility in data acquisition and recording. The system was studied on long distance flights and on strong maneuver flights. Signals of the LTN-90 system were compared with the data of the Precision Automated Tracking System laser radar. Application of fiber optics for data transmission of bit serial signals (200 Hz NRZ Code) is proved. The LTN-90 navigation system designed for surface aircraft can be applied without loss of accuracy.
