Aviation navigation equipment data acquisition system and method based on unmanned aerial vehicle

Abstract

The invention relates to the technical field of aviation navigation and flight verification, and discloses an aviation navigation equipment data acquisition system and method based on an unmanned aerial vehicle. The system comprises an unmanned aerial vehicle flight control system, a navigation equipment test antenna array, a multipath signal processing module, a signal acquisition module, an ADS-B emission module, a GNSS receiver, a UHF data link receiver, a power supply module and a ground station. The unmanned aerial vehicle carries a corresponding module, receives a signal of ground navigation equipment, carries out corresponding processing and storage, transmits data to the ground, receives a control instruction sent by the ground, and completes corresponding monitoring analysis and verification. Based on the flight technology of the unmanned aerial vehicle, the system and the method for acquiring the data of the aviation navigation equipment based on the unmanned aerial vehicle can reduce the flight verification cost and improve the flight verification efficiency, are effective supplementation of the existing flight verification of the manned aerial vehicle, and are also the development trend of the future flight verification.

Description

technical field [0001] The invention belongs to the technical field of aviation navigation and flight verification, and in particular relates to a data acquisition system and method for aviation navigation equipment based on an unmanned aerial vehicle. Background technique [0002] At present, due to the large number of equipment and complex parameter types in the fields of aviation navigation and oil drilling, various types of data need to be collected. Bus acquisition technology. Common fieldbuses such as RS232, 485, and 422 have simple structure, stable performance, reliable transmission, and strong interference capability, and are widely used in fields with high field requirements such as aviation and petroleum. [0003] Flight inspection refers to the use of flight inspection aircraft equipped with special inspection equipment to check and evaluate the quality and quality of space signals of various navigation, radar, communication and other equipment in accordance wit...

AI Technical Summary

Problems solved by technology

There are many kinds of equipment used in aviation navigation. The flight calibration system needs to collect and process the data of various navigation equipment to obtain the calibration data. At present, the flight calibration system carried by the calibration aircraft carries a variety of loads and is expensive. , the process is complicated, and the requirements for the reliability and safety of the flight aircraft itself are very high

[0004] With the increasing number of small and medium-sized airports in China, the demand for flight inspection is also increasing. Due to the limitation of inspection personnel and the number of available inspection aircraft, the existing man-machine flight inspection often cannot fly in time for airports that require flight inspection. calibration, thereby affecting the normal operation and use of the airport
