Online navigation equipment monitoring and flight verification system and method based on unmanned plane

Abstract

The invention relates to an online navigation equipment monitoring and flight verification system and method based on an unmanned plane. The system comprises a GPS antenna, a GPS positioning system module, an online navigation equipment monitoring and flight verification system module, a sensor module, an airborne computer module and an actuating mechanism module, wherein the online navigation equipment monitoring and flight verification system module comprises a test antenna, a central controller, a signal acquisition processing module, a signal monitoring analysis module and a flight verification module, the modules are embarked on the unmanned plane, the unmanned plane is made to realize flight according to a prescribed flight path to acquire navigation equipment signals, and corresponding monitoring analysis and verification are carried out. The system is advantaged in that through combination with the unmanned plane flight technology, measurement signals of the navigation equipment are made to be objective, comprehensive and effective, the analysis result is more reliable, higher precision is realized, and influence of equipment tests and flight verification on airport operation can be reduced.

Description

technical field [0001] The invention relates to the technical field, in particular to a system and method for on-line monitoring and flight verification of navigation equipment based on an unmanned aerial vehicle. Background technique [0002] Civil aviation navigation equipment is a very important equipment to ensure aviation safety, and its testing is currently receiving great attention at home and abroad. The International Civil Aviation Organization (ICAO), the International Radiocommunication Consultative Committee (CCIR) and the International Special Committee on Radio Interference (CISPR) In the relevant documents formulated and issued by various international organizations, relevant aviation navigation equipment performance testing and maintenance methods have been proposed. China Civil Aviation has also formulated relevant test procedures and requirements and flight inspection specifications for civil aviation navigation equipment. [0003] Civil aviation navigation...

Problems solved by technology

[0006] The traditional ground test method of current navigation equipment needs to be shut down for testing, and the test indicators are not comprehensive, and the test results are not continuous, which cannot fully reflect the operating status indicators of ILS and other navigation equipment, and also affect the operation of the airport.

The vehicle-mounted mobile measurement technology newly developed by R&S has improved compared with the traditional ground test methods. It can measure the signal of navigation equipment under the condition of near-field visibility, but it is limited by roads, terrains, obstacles, and measurement heights. The test results cannot effectively and reliably reflect the operating status of the navigation equipment, nor can it be used for flight verification
