4 月 10 日 4 时 47 points, China’s Xichang Satellite Launch Center” Long March III A “carrier rocket, successfully eighth Beidou navigation satellite into space transfer orbit. Data for: Compass satellite navigation system

Compass satellite navigation system construction of China has entered a critical period, will be completed in October this year, fully tested, with most parts of China to provide the initial conditions of service, next year to provide services for the Asia Pacific region.

in the recently held second session of the China Satellite Navigation academic annual meeting, according to China’s satellite navigation system management office Ran bearing its introduction, according to network launch plans, China has so far launched eight Compass navigation satellite, in addition to part of the satellite signal for system testing and validation testing, constitutes the “3 +3″ basic system.

Currently, the system has completed the ground segment equipment development, installation and commissioning, all functions operating normally, the user has completed the test section of the terminal development. 3-4 satellites will be launched this year, the satellite network, in most parts of our country and around the initial offer continuous passive positioning, navigation and timing services, as well as short-message communication service. Next year will launch 5-6 satellites satellite network for the Asia Pacific region provides passive positioning, navigation and timing services, and cover a wider position reporting services.

Compass system to ensure the achievement of development objectives and promote the quality and efficiency Compass application, the relevant departments will actively promote the policy initiatives to promote sound and rapid application development system construction.

system services, the Compass system is scheduled to be completed around the world to provide free, high quality, reliable service, and continue to improve performance.

in the application of industry, the public service will be gradually released Compass interface control documents, and other basic products to increase core chip technology research efforts, accelerate the Compass industry and regional demonstration projects to promote the core position to Compass services industry.

in key technologies, the system continued to promote the construction and application technology research, the formation of industry, academia and research, with the system, and further strengthen the basic science research and academic exchange; in international cooperation, and actively participate in the global satellite navigation system performance monitoring studies to promote the Compass is compatible with other satellite navigation systems and interoperability, to gradually integrate into the international civil aviation, maritime and other standards.
