The Chinese launch vehicle Changzheng-11 has launched nine high-resolution Earth remote sensing satellites into low-Earth orbit. This is one of the few launches that took place from a platform in the ocean.
The China Aerospace Science and Technology Corporation (CASC) has announced the successful launch of the Jilin One Earth Remote Sensing Satellite Group. The launch took place at 09:23 local time from an oceanic platform at an altitude of 160 m. The launch took place from the Yellow Sea.
This mission is only the second launch of Chinese satellites from the complex in the oceanic zone, the first took place on March 11, 2019. However, this is the first time that China has used new port facilities at Haiyan in the east of the country. China is only the third country (after the US and Russia) to launch from the ocean.
The nine Jilin-1 Gaofen-03 Earth observation satellites will provide data for Earth surveying, urban planning, disaster monitoring and other missions. The satellites are owned by Chang Guang Satellite Technology Co., Ltd. (CGST) is a commercial subsidiary of the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), part of the Chinese Academy of Sciences.
Six of these satellites are push camera satellites capable of returning detailed images of the planet. It is also indicated that this group includes three video satellites and six remote sensing devices. At the same time, the spacecraft launched into orbit will operate in the Jilin-1 satellite constellation, which is already operating in near-earth orbit.
China plans to create a group of 138 commercial Earth observation satellites capable of filming anywhere in the world five to seven times a day.
