Core tip: November 14th, the global navigation satellite system planning model unveiled the Ninth China International Aviation and Aerospace Exhibition, attracted great attention. The global satellite navigation system by our country independently developed, planned by a constellation of 30 satellites, has successfully launched 16 satellites. The system has a link between stars and autonomous navigation function, is expected to be completed in 2020 the global system establish the mission.

In November 14th, the global navigation satellite system planning model unveiled the Ninth China International Aviation and Aerospace Exhibition, attracted great attention. The global satellite navigation system by our country independently developed, planned by a constellation of 30 satellites, has successfully launched 16 satellites. The system has a link between stars and autonomous navigation function, is expected to be completed in 2020 the global system establish the mission.

According to Oriental network coverage, former China on the "Beidou" system is only known as " purely civilian equipment ", but this second Airshow China officially declassified complete the defense command and communication control system. This time the decryption was the ability of real. If in accordance with the overall structure it basically completed the first phase of deployment.

Beidou system from the current planning situation, can be divided into several stages of development, it not only has about 24-30 stars of different types of satellites and to finally form a set of complete control, communication, navigation, guidance and other multi-purpose satellite system. In addition the compass system and the United States of America 's " North American air defense network " ( BOAC ) system is somewhat similar, it also adopted the " multi level, multi airspace " structure system.

Navigation equipment is first applied to the general aviation RNP operation

According to the civil aviation resource net report, November 14th, Chinese civil aviation science and Technology Research Institute (hereinafter referred to as the " Air Academy " ) at the Zhuhai air show was released by the independent development of navigation technology new product RNP operation integrated avionics equipment. It is based on the /GPS compatible satellite navigation equipment, the multifunction display control unit ( MCDU ), the navigation display ( ND ), primary flight display ( PFD ) is highly integrated, make the domestic general aircraft have RNP running ability.

The equipment consists of air navigation academy institute of new technology research and development, to achieve flight plan, the actual navigation performance ( ANP ) calculation, enhanced ground proximity warning ( EGPWS ) and transverse and longitudinal navigation display and other functions, can be accurate, reliable flight to provide positioning and navigation service. Independent development of airborne navigation database, ARINC424 compliance, supports all 23 encoding, with all the airport approach, departure, approach and route data encoding, retrieval, according to flight plan combination; can display the current position of the aircraft navigation around the station, route and airport information.

The release conference scene, navigation technology research institute, He Yuncheng also shows by the Air Academy of independent research and development of RNP operation and ground support platform, the platform for domestic general aircraft RNP operation to provide navigation database checksum and RAIM availability prediction service.
