Charming Globe Jilin-1 Imaging Constellation

CGSTL announced plans to complete a 138-satellite Jilin-1 Earth-observation constellation during China’s 14th Five-Year Plan, with a target of 60 satellites on orbit in 2021.

11 Mar 21: Chinese EO company #CGSTL announced that they would complete their 138-satellite Earth observation constellation during the 14th Five-Year-Plan (2021-2025). This effort also includes reaching 60 satellites in orbit this year (there are currently 25 “Jilin-1” satellites on orbit).

– CGSTL (aka Charming Globe) is one of the most developed commercial Earth Observation (EO) companies in China, and is a spin-off from the Changchun Institute of Optics and Fine Mechanics.

– CGSTL raised $375M (US) in Nov. 2020, making it the best funded EO company worldwide.

– CGSTL has produced a variety of Chinese commercial satellites. Most have been <100kg but CGSTL also manufactured the high resolution KF-01 with a mass of 1.25 tons.

– In September 20, CGSTL launched 9 satellites from an ocean barge based LM-11. To reach their goal of 60 satellites on orbit by the end of 2021 they would need to conduct another 4 such launches. See Launch VIDEO.

– The Jilin-1/Gaofen-03 (Jilin-1 High Resolution-03) satellites have a mass of less than 40 kg, and includes video satellites and push-broom imaging satellites. Their orbits range from 450-650km in altitude.

– The push-broom satellites are able to obtain images with panchromatic resolution better than 1 m, multi-spectral resolution better than 4 m, and with a swath width larger than 17 km. The video satellites can obtain color video images with a resolution better than 1.2 m and a coverage area not less than 14.4 km × 6 km.

– With funding secured and established manufacturing processes CGSTL has reached “batch production” capability.

CGSTL is China’s leading commercial earth observation company and is positioning itself to compete in the global market for earth sensing services. With increasing numbers of satellites on orbit CGSTL is able to reduce the time required to image any area of interest on the globe. The desired end-state is a constellation capable of capturing and transmitting an image anywhere on earth in 10 minutes or less.
