A Long March 3B booster lifted off from Xichang Satellite Launch Center with two Beidou navigation satellites bound for medium Earth orbit. It was the 23rd successful launch of the year with no failures.
To date, China has launched six boosters with 11 Beidou satellites aboard in 2018. The navigation satellite system, which is similar to the U.S. Global Positioning System and Europe’s Galileo constellation, will eventually have 35 satellites in orbit.
China’s launch total for 2018 is expected to be in the low to mid-30’s.
