Measurement Method and System for Navigation Signal and Online Diagnosis Method and System for Navigation Equipment

Abstract

Due to the influence of the surrounding environment of airport’s navigation equipment, the existing measurement technology cannot carry out fault diagnosis of navigation equipment according to the results of the measurement system of the navigation equipment, and the staff can only carry out artificial fault diagnosis according to their experience. However, the artificial diagnosis results may be inaccurate. This paper proposes a navigation signal measurement method and system, in order to eliminate or reduce the environmental factors interference to the measurement, so that the navigation equipment test system can measures the navigation signal more accurately, and obtains more accurate measurement results. Based on the measurement results, this paper also proposes an online diagnosis method and system for navigation equipment, which can realize the online diagnosis of navigation equipment and has a high accuracy.
