China launched two remote-sensing micro-nano satellites on a Long March-4B rocket from Jiuquan Satellite Launch Center in northwest China's Gobi Desert Thursday.

The OVS-1A and the OVS-1B, the first two satellites of Zhuhai-I remote-sensing micro-nano satellite constellation, are expected to improve the monitoring of geographical, environmental, and geological changes across the country, according to Beijing Institute of Space Science and Technology Information.
