Problems solved by technology

However, UAT broadcasts the aircraft's own information, and anyone can receive the ADS-B signal, which has security issues.
At the same time, UAT works on 978MHz, which will cause serious interference to DME ground facilities

Abstract

The invention provides a general airborne navigation system based on a ground mobile communication network, which comprises a general airborne navigation base station used for transmitting a navigation signal to a preset airspace range of 0-3000m by a ground mobile communication channel, a general aircraft, and general airborne equipment which is arranged on the general aircraft and is used for calculating by utilizing the navigation signal, three-dimensional coordinate information of the general airborne navigation base station and altitude data and height information of the general aircraftto obtain position information of the general aircraft, wherein the communication channel employed for navigation is a unidirectional transmission mode, which transmits the navigation signal in a form of broadcast. According to the embodiment of the invention, the navigation system has short construction cycle and low construction cost and can meet high-efficiency general airborne navigation positioning demand. In addition, because the special ground mobile communication channel and antenna design are employed in the general airborne navigation system, the navigation system cannot generate aninterference with not only a civil aircraft navigation system but ground mobile communication user and system.

Description

technical field [0001] The invention relates to the technical field of aviation navigation, in particular to a general aviation navigation system (GAMAS, General Aviation Mobile Navigation System) based on a ground mobile communication network. Background technique [0002] General aviation (GA, General Aviation) refers to aviation activities other than military, police, customs anti-smuggling flights and public air transport flights, including operational flights engaged in industry, agriculture, forestry, fishery and construction, as well as medical and health, emergency rescue and disaster relief , meteorological detection, ocean monitoring, scientific experiments, education and training, cultural and sports and other aspects of flight activities. In recent years, GA has developed extremely rapidly around the world. At present, there are 320,000 GA aircraft in the world, while only more than 60,000 are flying in civil aviation routes. In North America, where GA is most p...
