A 4G/3G/BDS-based general aviation aircraft communication navigation monitoring system and method

Abstract

The invention relates to a navigation airplane communication navigation monitoring system and method based on 4G / 3G / BDS. An airborne communication navigation terminal is further provided. A ground communication navigation monitoring server is communicated with a control analog machine and a radar data computer in an Ethernet / USB / serial port mode and obtains communication navigation monitoring data and flight control data provided by the control analog machine and the radar data computer. The airborne communication navigation terminal is used for communication and navigation of an airplane. The ground communication navigation monitoring server is used for airplane information processing and feedback, and is provided with airplane crashproof early warning and data recording analysis functions. According to the invention, the previous point-to-point communication mode is broken through, a base station of a 4G / 3G cellular network wide in coverage area is used for signal transfer, over-distance trace tracking and display of a plurality of airplanes is realized based on an internet, and the ground server is utilized to display traces of all networked airplanes through a browser.

Description

technical field [0001] The present invention relates to a 4G / 3G / BDS-based general aviation aircraft communication navigation monitoring system and method, in particular to a communication method based on a BDS-based 4G / 3G cellular network designed air-to-ground data exchange chain and related hardware systems, suitable for The field of communication, navigation and surveillance of general aviation aircraft. Background technique [0002] my country's 4G / 3G cellular mobile communication network has a wide coverage, fast transmission rate, good reliability, and strong real-time performance. It can provide general aviation aircraft with the infrastructure support required for communication and navigation. At the same time, my country's Beidou satellite navigation system has provided all-weather and all-day positioning and timing services to the Asia-Pacific region. Its positioning accuracy is 10 meters, and its speed measurement accuracy is 0.2 meters per second, which are compa...

Problems solved by technology

[0005] The existing communication and navigation equipment of general aviation aircraft is expensive and requires professional maintenance, and as the number of aircraft increases, the pressure on ground communication and navigation equipment will be greatly increased, occupying the resources of civil aviation aircraft

[0006] The existing surveillance methods of general aviation aircraft mainly rely on the voice reports of pilots. Some people are also using ADS-B technology on large passenger aircraft. However, ADS-B technology requires special area designation and the deployment of a large number of ground base stations, which is expensive and inconvenient to maintain. , at the same time, the airborne ADS-B transmitting and receiving devices have high power consumption and are expensive
