Yesterday, China launched its 30th and last satellite to complete its own global navigation system BeiDou. The country started the program in the 1990s to launch the first phase. The latest satellite launch is part of the third phase of the program that began in 2015. 

The launch was initially scheduled for June 16, however it was postponed for a week after technical difficulties. Yesterday, China’s space agency was able to successfully execute the liftoff with the satellite mounted on the Long March-3B rocket.
