The invention provides an instrument landing system same-frequency and different-call operation monitoring system. The system includes: monitoring antenna, measuring device and monitoring device. The monitoring antenna is used to receive space signals transmitted by navigation equipment with different calls on the same frequency; the measuring device includes a multi-channel receiver and a multi-channel receiver controller; the multi-channel receiver receives each space signal under the control of the receiver controller And extract the received space signals to obtain the parameter indicators of each space signal; the monitoring device receives the parameter indicators of each space signal, and evaluates or predicts the working status of each navigation device according to the parameter indicators of each space signal; the monitoring device also according to The parameter index of the signal in space transmitted by each navigation device determines the interlocking state of each navigation device. The invention comprehensively analyzes the signal parameter indexes emitted by each navigation equipment, determines whether the running state of each navigation equipment is normal, and whether the interlocking state is invalid, and provides guarantee for the safe operation of the instrument landing system.
Description
technical field [0001] The invention relates to the technical field of aviation navigation monitoring, in particular to a monitoring system and method for same-frequency and different-call operation of an instrument landing system. Background technique [0002] The Instrument Landing System (ILS) is the most widely used aircraft precision approach and landing guidance system, generally including: localizer (LOC, frequency band: 108-112MHz), glide beacon (GP, frequency band : 328-334MHz) and distance meter (DME, frequency band: 960-1215MHz). [0003] Electromagnetic spectrum resources are the basic strategic resources to support airport construction and development. In many countries, in order to solve the shortage of ILS working frequency resources in dense airport areas, two sets of ILS operating frequencies are usually assigned to both ends of the same runway. The same pair of frequencies, but with different identification numbers (call signs), during operation, the two s...
