All-purpose aircraft airborne system and communication supervision system based on Tiantong-01 satellite

Abstract

The invention provides an all-purpose aircraft airborne system and a communication supervision system based on the Tiantong-01 satellite. The communication supervision system comprises the all-purposeaircraft airborne system, a ground data processing system, and a satellite system. The satellite system is a Tiantong communication satellite, and serves as a communication circuit of the all-purposeaircraft airborne system and the ground data processing system. The ground data processing system tracks the flight position and track of an aircraft according to the positioning information transmitted by the all-purpose aircraft airborne system, and achieves the real-time voice and data communication. The communication supervision system can carry out the automatic switching of a transmission mode according to the intensity of different satellite signals, and achieve the selective call of one or more all-purpose aircrafts from the ground through the voice communication function of the Tiantong-01 satellite while achieving the voice communication between the ground and the all-purpose aircrafts. The system can achieve the seamless supervision and voice communication of the all-purpose aircrafts in an integrated manner, thereby greatly saving the construction and operation cost of the ground equipment.

Description

technical field [0001] The technology relates to the technical field of general aviation, especially a general aviation airborne system integrating voice communication and monitoring signal transmission and a corresponding ground data processing system. Background technique [0002] In recent years, with the continuous deepening of my country's low-altitude airspace reform, general aviation has ushered in a period of rapid development. However, due to the lack of communication and surveillance technology, the relevant departments cannot realize the effective surveillance of general aircraft, nor can they realize the real-time voice communication between the ground and aircraft, which restricts the development of general aviation. The current general aviation voice communication and surveillance technologies mainly include: [0003] In terms of ground-air voice communication, the current general aircraft is also equipped with very high frequency (VHF) airborne equipment, and...

Problems solved by technology

[0008] Therefore, in terms of general aviation surveillance, although ADS-B, 4G, Beidou short message technology or multi-mode technology can be used to transmit the positioning information of general aircraft, it is still difficult to meet the requirements of general aviation surveillance

One is that ADS-B, like VHF, needs to build a large number of stations on the ground and rent a large number of transmission circuits, whic
