Beidou-based flight navigation system and method

Abstract

The invention, which belongs to the field of satellite navigation, discloses a Beidou-based flight navigation system and method. The system comprises a navigation computer, a control panel, a displaydevice, a Beidou antenna and a Beidou receiver. The navigation computer includes a processor, a database, a memory and a communication interface. Under operation of the navigation software, aircraft position calculation, flight plan management, navigation task calculation and graphic display are completed. The display device provides functions of map interface display and flight plan management window display. The Beidou receiver receives a satellite signal through the Beidou antenna to complete position solution. According to the invention, leg information calculation and real-time navigationcalculation are performed based on an established flight plan; and a needed track angle, a distance, an azimuth angle, estimated arrival time, estimated flight time, a track angle error and horizontal deviation are calculated.

Description

technical field [0001] The invention belongs to the field of satellite navigation, in particular to a Beidou-based flight navigation system and method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Modern aircraft navigation is based on radio navigation equipment and GPS equipment, and navigation calculations are completed by flight management computers. For areas lacking road-based navigation facilities, only GPS navigation can be relied on. And with the development of satellite navigation technology, aircraft gradually transition to PBN navigation based on satellite navigation. However, only the GPS navigation system cannot fully meet the requirements of PBN navigation technology in terms of accuracy, integrity, consistency and availability. Moreover, the GPS navigation system is controlled by foreign countries, and its stability and safety in other parts of the world cannot be guaranteed. Wit...

AI Technical Summary

Problems solved by technology

[0005] Existing aircraft only have GPS as a satellite navigation technology, which cannot fully meet the requirements of PBN navigation technology in terms of accuracy, integrity, consistency and availability

[0006] For areas that lack road-based navigation facilities, they can only rely on GPS navigation, which has poor stability and safety performance

The stability and safety of the GPS navigation system in other parts of the world cannot be guaranteed

[0007] The existing technology cannot add the Beidou navigation system to the airborne equipment, resulting in the inability of Beidou to be applied in aviation navigation
