Carrier rockets place four satellites into orbit

About 13 hours later, a Long March 2D rocket lifted off at 3 pm at the Jiuquan Satellite Launch Center in northwestern China's Gobi Desert and then placed the Yaogan 37 and Shiyan 22A and 22B satellites into their preset orbits, CASC said in a separate release.

All of the three satellites are tasked with monitoring and surveying the space environment, the space conglomerate said.
