Abstract

The invention discloses an aircraft based on Beidou short messages and an emergency navigation communication system. The aircraft comprises a front electronic cabin and a rear passenger cabin. Airborne interface equipment, an inertial measurement unit, a flight management system, an electronic flight bag, a multimode receiver and a communication management unit/air traffic service unit are arranged in the front electronic cabin; the rear passenger cabin comprises a positioning module; the positioning module determines the final position of the aircraft by adopting a positioning mode automatic selection method based on the multi-constellation multi-frequency-point signal; and the flight management system formulates an optimal flight plan according to the first positioning parameter or the second positioning parameter. The positioning module is upgraded, the final position of the aircraft is determined by adopting a positioning mode automatic selection method based on the multi-constellation multi-frequency-point signal, a second positioning parameter for multi-frequency-point accurate positioning is realized, and a scheme for formulating an optimal flight plan and realizing automatic control of a flight task under special conditions is also given.

Description

technical field [0001] The invention relates to the technical field of aviation navigation and communication, in particular to an aircraft and an emergency navigation communication system based on Beidou short messages. Background technique [0002] Beidou short message communication means that the satellite positioning terminal and Beidou satellite or Beidou ground monitoring center can directly carry out two-way information transmission through satellite signals. It has three basic functions of position reporting, emergency search and rescue and message communication. It is the independent innovation of Beidou system , Communication and navigation integration and innovative characteristic services. The Beidou-3 system short message communication service includes global short message communication (GSMC) service and regional short message communication (RSMC) service. Among them, the GSMC service uses the link between 14 medium-circular earth orbit (MEO) satellites and Bei...
