Beidou system accuracy tied for first with GPS
A positioning accuracy of the Beidou system can be further adjusted to improveThe Beidou satellite navigation systems spokesman said
Big Dipper can be higher than the GPS positioning accuracy of China and the surrounding areas-I
As milestones, covering most parts of China and the Asia-Pacific "Beidou satellite navigation (regional) system also needed by the 4 track, five geosynchronous orbit and five tilt geosynchronous orbit satellite network. China and the surrounding area positioning accuracy can be higher than the GPS-system. The Beidou only place one orbit, four geosynchronous orbit and five inclined geosynchronous orbit satellite, officially announced major performance service area to 84 degrees east longitude to 160 degrees, 55 degrees south latitude to 55 degrees north latitude. region.
A positioning accuracy of the Beidou system can be further adjusted to improve
The Beidou satellite navigation system spokesman said, will provide free worldwide positioning, velocity and timing services, the positioning accuracy of 10 meters, velocity accuracy of 0.2 m / sec, 10 nanosecond timing accuracy. Pre-system test assessment indicates that, the Beidou satellite navigation system with a positioning accuracy of about 25 m. GPS civil coding error during the test run to reach about 100 meters, but the adjustment soon after the completion of 10 m level. After adjust the atomic clock error and satellite orbit measurement accuracy of satellite operation stability test adjustment, the positioning accuracy of the Beidou system will reach about 10 meters.
2, the positioning accuracy of the Beidou system will be shoulder to shoulder with the GPS
The military code positioning accuracy of GPS system for 1 meter, the civil code positioning accuracy of about 10 meters. Announced the Beidou system is now 10 meters error accuracy is also against civil code, the military system will use another coding system. Big Dipper as a latecomer, now declare that the design indicators, positioning, timing accuracy is not inferior to the United States is now GPS-II system.
"In the global satellite navigation market, the U.S. GPS development as early as the share has exceeded 95%, this will be the biggest challenge facing China's Beidou navigation system into the application. Wu, director of the Office of the navigation project of China Aerospace Science and Technology Corporation East March 12, 2012 in an exclusive interview with Science and Technology Daily said.
Beidou navigation system has nine network satellite has been built to cover the basic system of our country and the surrounding areas, and provide commissioning services. Main products: car dvd player and car dvd , are with good quality. The end of the year, the system will achieve a 14 star network, complete the construction of the Asia-Pacific regional navigation system put into formal operation.
Face of a strong rival to the long-term dominates, the application prospects of the "Compass" has attracted people concern.In this regard, the National People's Congress, China Aerospace Science and Technology Corporation, deputy general manager Zhang Jianheng seem confident. He recently told the media: "It is envisaged that the 'second five' during the Beidou navigation satellite business applications will spurt."
