China launched its fourth Long March-11 rocket on Thursday, carrying a multiple small satellites into orbit. The launch took place from a mobile launch platform from the Jiuquan Satellite Launch Center at 04:42 UTC.
Onboard the LM-11 rocket was the OVS-2 upgraded version of Zhuhai-1 video satellite and four hyperspectral satellites from the OHS-2s series.

Developed by the Zhuhai Obit Space Science and Technology Co., Ltd., the Zhuhai-1 earth observation satellites are the video component of the Chinese Orbital earth observation system. Two OVS-1 (OVS-1a and OVS-1b) satellites launched on June 16, 2017, constituted the prototype OVS-1 video component of the system. The operational Orbita constellation is to consist of video satellites (OVS-2), hyperspectral satellites (OHS-2) and small personal satellites (OPS-2).
The new up upgraded version of the previously launched video satellites has a resolution of 0.9 meters, which will greatly improve the spatial resolution and data acquisition capabilities of the previous satellites orbited in the system (with a resolution of 1.98 meters). Images obtained cover an area of 25km x 2.7km, approximately 67.5 square kilometers.

The four new hyperspectral satellites have a resolution of 10 meters. This is the first-generation of hyperspectral satellites launched by private enterprises in China, having a broad market potential. Images obtained cover an area of 140km×0.24km, approximately 33.6 square kilometers. The four satellites have a global coverage once every five days.
The OHS-1-01 satellite is also known as ‘Qingkeda-1’ and was developed in cooperation with the Qingdao University of Science and Technology. The OHS-1-03 satellite is also known as ‘Guiyang-1’.
