A Long March-3B carrier rocket carrying a new-generation Beidou satellite lifts off from the Xichang Satellite Launch Center in Xichang, southwest China's Sichuan Province, Sept. 30, 2015. China sent a new-generation satellite into orbit that will support its global navigation and positioning network at 7:13 a.m. Beijing Time Wednesday (2313 GMT Tuesday). It was the 20th satellite for the Beidou Navigation Satellite System (BDS), and put China one step closer to providing an alternative to the U.S.-operated GPS. (Photo: Xinhua/Li Xiang)
