Abstract (English):
The results of precision evaluation of the range measuring channels for short-range navigation systems are presented. The evaluation is performed taking into account the features of the hardware implementation of on-board and ground equipment of short-range navigation systems, the radio navigation signal processing algorithms, the format of the signals of the range measuring channels as well as interference environment. The influence of reflections from local objects is considered as well as signal distortions in on-board receiver and inaccuracies in the ground range-azimuth beacon. Taking into account these interfering factors, the overall error in the range finding is determined as well as the part of the error introduced by the equipment of the ground range-azimuth beacon.
