Big Dipper autonomous navigation method based on Big Dipper short message and 4G communication mode

Abstract

The invention discloses a Big Dipper autonomous navigation method based on a Big Dipper short message and a 4G communication mode. Namely, a Big Dipper type airborne device acquires information of the current position, speed, time and the like of an airplane in real time and issues the information in the form of an ADS-C message according to the requirement of a ground system. Meanwhile, a ground low altitude flight operation monitoring system receives airspace situation information from other systems, and after coding and processing the situation of the other airplanes around a target airplane, the ground low altitude flight operation monitoring system sends the situation to the Big Dipper type airborne device in the form of the short message through a Big Dipper directing type user machine or the 4G communication device. According to the Big Dipper autonomous navigation method, the positioning information sent by the Big Dipper type airborne device can be received, monitoring can be achieved at a low altitude, flying data of the position, height, speed and the like in the flying process of a navigation aircraft can be recorded in real time through an airborne data recording module, emergency directing communication can be conducted on the aircraft loaded with the Big Dipper type airborne device through a Big Dipper short message channel, and low altitude navigation seamless coverage can be achieved.

Description

technical field [0001] The invention relates to a Beidou autonomous navigation method based on Beidou short messages and 4G communication mode, and belongs to the general aviation application technical field of air traffic control. Background technique [0002] At present, the traditional existing technology usually uses technologies such as secondary radar and ADS (Automatic Dependent Surveillance, Automatic Dependent Surveillance) to monitor the low-altitude airspace to solve the problem of "invisible (beyond the horizon cannot be identified)" of low-altitude aircraft. The shortcomings of the existing technology of secondary radar are low radar coverage and poor maneuverability; and the use of ADS technology to solve the monitoring of low-altitude airspace that cannot be covered by existing air traffic control radars requires the establishment of ground stations, which will greatly increase costs At the same time, it is impossible to effectively monitor low-altitude aircra...
