Beidou dual-mode terminal equipment based on navigation ADS-B application and control method thereof

Abstract

The invention provides Beidou dual-mode terminal equipment based on a navigation ADS-B application. The Beidou dual-mode terminal equipment comprises a baseband processing unit, a digital-to-analog processing unit and an antenna unit. The key resides in that the baseband processing unit comprises an RNSS module and an RDSS module. The mode of combination of the RDSS module and the RNSS module is adopted, position information of an aircraft is measured by utilizing the RNSS module and then position reporting is performed to the air traffic control department by utilizing the inbound short message service of the RDSS module. The RDSS module adopts the basic principle of an integrated scheduling mechanism of multiple IC user cards and is divided into two modes of a static mode and a dynamic mode so that the use requirements of users under different scenes can be flexibly supported, the situation that the positioning data source of an ADS-B system uses the GPS for a long time can be solved, the Beidou resources of our country can be fully utilized and security and confidentiality can be enhanced.

Description

technical field [0001] The invention relates to the technical field of aviation control, in particular to a Beidou dual-mode terminal device based on the general aviation ADS-B application and a control method thereof. Background technique [0002] With the rapid development of the aviation industry and the gradual and comprehensive opening of low-altitude airspace, my country's general aviation (referred to as "general aviation") industry has entered a period of rapid growth. With the rapid increase in the number of general aviation aircraft, it poses a severe challenge to my country's air traffic control . Compared with civil aviation, general aviation has the characteristics of low flying altitude, various types of aircraft, and complex and changeable flight areas, which makes it difficult for existing civil air traffic control surveillance radars and communication equipment to effectively guarantee the monitoring and communication capabilities of low-altitude flights.
