Jilin-1 SP project
Jilin is a constellation of Earth observation satellites developed by the Chinese company Chang Guang Satellite Technology. The two sensors of Jilin-1 Hyperspectral Satellite were successfully launched in January 2019.
The Jilin satellites aim to commercialise satellite space imagery. Therefore, they provide high resolution satellite imagery of 5 meters with 27 hyperspectral bands. Jilin-1 is useful for mapping, environmental monitoring, forestry, energy, land use planning and agriculture.
The unit is involved in this project in several areas. It assesses all key aspects of sensor data quality. These data are then compared with the requirements or specifications of the product sensors. This process uses the sample of sensor products provided.
