Jilin Daily Vision
75 cm Resolution, 18 daily image updates
A Chinese commercial constellation of two very high-resolution satellites in the same polar orbit; operational since December 7, 2019. The satellites offer a revisit rate of every two days to provide images with 75 cm resolution. These two satellites provide 75 cm resolution images across a swath width of 40 km.
Thanks to their agility, the Jilin-1GF-02A/B/D/F satellites offer both monoscopic and stereoscopic imaging capabilities. These four satellites are equipped with a dual-camera system featuring a long focal length and precise dual-frequency orbit determination capabilities.
