Navigation satellites sent into Earth orbit

China launched a pair of navigation satellites on Monday afternoon, moving closer to building a global network.

The 28th and 29th satellites in the domestically developed Beidou Navigation Satellite System, one of the nation's largest space programs, were lifted atop a Long March 3B carrier rocket at the Xichang Satellite Launch Center.

They are the fifth and sixth in the third-generation of Beidou satellite. They will conduct in-orbit tests and then be connected with the previous four third-generation Beidou satellites, said a statement from the China Satellite Navigation Office.
