XICHANG, Nov. 2-- China's home-grown global satellite navigation system came a step closer to completion with the launch of another BeiDou-3 satellite at 11:57 p.m. Thursday from the Xichang Satellite Launch Center, in the southwestern Sichuan Province. Launched on a Long March-3B carrier rocket, it is the 41st of the BeiDou navigation system, and will work with 16 other Beidou-3 satellites already in orbit. It is also the first BeiDou-3 satellite in high orbit, about 36,000 km above the Earth. In a geostationary orbit, following the Earth's rotation, it will view the same point on Earth continuously. A basic system with BeiDou-3 satellites orbiting will be in place by the year-end to serve countries in the China-proposed Belt and Road Initiative, said Yang Changfeng, chief designer of the system. The satellite and rocket for Thursday's launch were developed by the China Academy of Space Technology and the China Academy of Launch Vehicle Technology, respectively. The launch was the 290th mission of the Long March carrier rocket series. Apart from radio navigation system, the satellite is equipped with an improved radio determination satellite service that can provide short message services to 10 million subscribers each hour. With an advanced satellite-based augmentation system, the satellite can also provide low-cost and reliable navigation services to civil aviation clients at home and abroad. |
