Abstract

The invention provides a multi-mode receiver ground-based augmentation technology device and a processing method. A GNSS receiving assembly receives satellite navigation signal data and SBAS augmentation signal data; a VDB receiving assembly receives GBAS enhanced signal data; a GLS processing assembly analyzes received GNSS receiving assembly data and VDB receiving assembly data; landing guidancecalculation is carried out according to a working mode selection command and a wave channel selection control command sent by an interface processing assembly, and the interface processing assembly converts navigation and landing guidance data into bus signals and sound analog quantity output signals. According to the method, the overall availability of a satellite navigation system is improved,the positioning precision is improved, the positioning precision and integrity of satellite navigation in an airway and a non-precision approach area are improved, and the positioning precision, integrity and availability of satellite navigation in a precision approach area are improved.

Description

technical field [0001] The invention relates to airborne satellite navigation, in particular to a device and a processing method of satellite navigation enhancement technology. Background technique [0002] The Global Navigation Satellite System (GNSS) currently recognized by the International Civil Aviation Organization (ICAO) includes the Global Positioning System (GPS) of the United States, the Global Navigation Satellite System (GLONASS) of Russia, the Beidou Satellite Navigation System (BDS) of China and the Galileo satellite of Europe Four core constellations of the navigation system (GALILEO). ICAO has long promoted the adoption of GNSS technology as the primary means of navigation for all phases of aircraft flight. With the improvement of the GNSS system and the continuous development and progress of various augmentation systems, it provides technical support for the application of civil aviation GNSS. As the main navigation source for future civil aviation operatio...
