Embodiment Construction

[0052] The content of the present invention will be described in further detail below in conjunction with the drawings and specific embodiments.

[0053] With the continuous development of navigation technology, various types of navigation equipment and navigation methods have been installed on general aircraft airborne platforms, including satellite navigation, radio navigation, position calculation, and so on. Each kind of navigation equipment can work independently under certain conditions and provide the current position information of the aircraft. In an integrated navigation system, a single navigation system is only equivalent to a sensor, and the redundancy technology of a single navigation system is only equivalent to a sensor-level redundancy in an integrated navigation system. Modern aircraft have put forward higher and higher requirements for the accuracy and reliability of the navigation system. It is very limited to achieve the required accuracy and reliability by i...

Abstract

The invention relates to a universal aircraft airborne integrated navigation system and method, and solves the problems of single navigation mode, low navigation precision and reliability and incapability of realizing an autonomous navigation function of the existing universal aircrafts. The system comprises a navigation data receiving module, a navigation mode judging module and a navigation positioning resolving module; the navigation data receiving module is used for receiving real-time information sent by airborne receiving equipment, and the airborne receiving equipment comprises a GPS / Beidou satellite receiver, a VOR receiver, a DME receiver and an atmospheric navigation attitude system; the navigation mode judgment module is used for judging which navigation mode is adopted for comprehensive positioning, and the navigation modes comprise a GPS / Beidou satellite navigation mode, a radio DME / DME navigation mode, a radio VOR / DME navigation mode and a bitwise reckoning navigation mode; and the navigation positioning resolving module is used for calculating position information of a current airplane according to the selected navigation mode.

Description

Technical field [0001] The invention belongs to the field of airborne avionics systems, and relates to a general-purpose aircraft airborne integrated navigation system and navigation method. Background technique [0002] General aircraft airborne integrated navigation equipment is part of the onboard integrated electronic system. The integrated navigation equipment provides navigation and positioning results for the navigation function of the flight management system. For civil large passenger aircraft, GPS / INS, GPS / radio / INS integrated navigation methods are mainly used. Inertial navigation INS is used as an autonomous navigation device and does not require external equipment to participate. INS is used as the main navigation method during navigation to avoid high altitude During long-distance flight in the airspace, autonomous navigation can be carried out under conditions such as GPS interference failure and radio navigation signal obstruction. However, due to the high cost of...
