At present, China has successfully launched 4 Beidou navigation test satellites and 16 Beidou navigation satellites, the second step goal of the "three-step" strategy of Beidou navigation project construction - Beidou satellite navigation regional networking has been successfully realized, and the accuracy and level of Beidou navigation system in the Asia-Pacific region are not inferior to GPS global positioning system. He said that China should speed up the formulation and improvement of relevant policies for the navigation industry and guide the orderly development of the navigation industry.
"China's Beidou satellite navigation system is developing very fast." Yang Yuanxi said that from the completion of the Beidou satellite navigation test system in 2000 to the official provision of regional services by the Beidou satellite navigation system at the end of 2012, and the formal provision of continuous passive positioning, navigation, timing and other services to most of the Asia-Pacific region, China has become one of the four major satellite positioning and navigation systems in the world in just over a decade.
According to the plan, by around 2020, China will build the Beidou global satellite navigation system composed of 5 geostationary satellites and 30 non-geostationary satellites to provide high-precision and highly reliable positioning, navigation and timing services covering the world.
"The Beidou satellite navigation system is a global satellite navigation system independently built and operated by China and compatible with other satellite navigation systems in the world. Although there is still room for improvement in some technical levels, from the perspective of operating effects, the accuracy and level in the Asia-Pacific region are not inferior to GPS. Yang Yuanxi said, "And Beidou has its own characteristics, not only navigation and positioning timing, but also communication functions." Insist on carrying forward their own characteristic advantages and providing high-quality services, then there will be a foothold in the domestic and future international markets. ”
