Jilin-1 (simplified Chinese: 吉林一号; traditional Chinese: 吉林一號; pinyin: Jí Lín Yī Hào) is China's first self-developed commercial remote sensing satellite system. The satellites are operated by Chang Guang Satellite Technology Corporation and named after Jilin Province where the company is headquartered.[1] The first set of satellites were launched by Long March 2D in Jiuquan Satellite Launch Center on 7 October 2015, at 04:13 UTC.[2] All launched Jilin-1 satellites are in Sun-synchronous orbit (SSO).

As of 15 June 2023, there were a total of 25 launches of Jilin-1, and 130 satellites in orbit. Chang Guang originally planned to launch 138 total satellites by the year 2025, but expanded its goal in 2022 to 300 satellites[3] Jilin-1 is the largest Chinese commercial satellite constellation in orbit and has enjoyed generous funding since the Chinese government opened satellite imagery to private ventures.[3] Chang Guang received $375 million (USD) of funding for the Jilin-1 program in November 2020.[3][4]
