China launched four satellites to provide photographs to commercial clients while helping with harvest assessment, geological disaster prevention and resource surveys. The launch of the Jilin-1 mission took place at 04:13 UTC on Wednesday, using a Long March-2D launch vehicle from the 603 Launch Pad at the Jiuquan Satellite Launch Center’s LC43.
China launches commercial remote-sensing satellites
The Jilin-1 mission was developed on the China’s Jilin Province and is the country’s first self-developed remote sensing satellite for commercial use. Jilin-1 consists of four satellites, one for high-definition images, one for testing new space technology and another two for video.
Data will be provided to commercial clients to help them forecast and mitigate geological disasters, as well as shorten the time scale for the exploration of natural resources. The satellites were developed by the Chang Guang Satellite Technology Co., Ltd under the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences.

Jilin-1 is a 420 kg high-definition optical satellite with a 0.72 m resolution pan-chromatic camera and 4 m resolution multi-spectral camera. It is equipped with three deployable solar panels for power generation that will be stored in internal batteries. The satellite will operate on a 656 km sun synchronous orbit.

From 2030 the Jilin constellation will have 138 satellites in orbit, forming a all-day, all-weather, full spectrum acquisition segment data and a capability of observing any global arbitrary point with a 10 minutes revisit capability, providing the world’s highest spatial resolution and time resolution space information products.
