Embodiment Construction

[0036] According to the working principle of instrument landing system glide beacons, localizers and omnidirectional beacons, combined with the ground test requirements of navigation equipment determined by ICAO DOC8071 and the "Civil Aviation Traffic Management Communication Navigation Surveillance Equipment Inspection" issued by the Air Traffic Management Bureau of the Civil Aviation Administration of China Overhaul Management Regulations, the navigation online monitoring system mainly completes the following indicators:

[0037] --- Localizer track structure;

[0038] --- Localizer coverage;

[0039] --- Localizer linear coverage;

[0040] ---Sliding slide cover;

[0041] ---Sliding platform end-fired transverse structure;

[0042] ---Pointing frequency and code;

[0043] --- Signal measurement of omnidirectional beacon station.

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] like figure...

Abstract

The invention relates to an on-line monitoring system and method for navigation equipment. The monitoring system includes a test antenna, a GPS antenna, an antenna control module, a radio frequency acquisition and processing module, a signal analysis module and a central controller module. The test antenna is used to obtain the ILS / VOR space signal of the instrument landing system; the GPS antenna is used to receive satellite signals; the antenna control module transmits the signals received by the test antenna and the GPS antenna to the radio frequency acquisition and processing module; radio frequency acquisition and processing The module filters, demodulates and calculates the received signal, obtains relevant parameter data, and transmits the relevant parameter data to the signal analysis module; the signal analysis module analyzes the received data, and transmits the analysis result to the central controller module. The invention can determine the precise position measurement point of the waterway, and improves the measurement precision and accuracy of the online monitoring system of the navigation equipment.

Description

technical field [0001] The invention relates to a monitoring system and method, in particular to an online monitoring system and method of a navigation device. Background technique [0002] Civil aviation navigation equipment is the most important infrastructure of civil aviation and is closely related to flight safety. With the continuous growth of flight traffic and the implementation of ILS operations in domestic large airports II and III, airport operations rely more and more on navigation facilities, which puts forward higher requirements for navigation equipment performance and operation guarantee. In addition to regular flight inspections, inspections of navigation equipment, maintenance tests, and operation tests under special weather conditions have become important means to ensure aviation flight safety. The current traditional ground testing methods for navigation equipment need to be shut down for testing, and the test indicators are not comprehensive. They cann...
