Resolution 75 cm, Stereo collection capability
A Chinese commercial constellation of two ultra-high resolution satellites in the same polar orbit; in operation since December 7, 2019. With the EarthScanner and JL1GXA satellites have a daily revisit capability to offer 75 cm resolution images. These 2 satellites offer an image resolution of 75 cm over a swath width of 40 km.
Jilin-1GF-02A and 2B offer a monoscopic and stereoscopic acquisition capability. These two satellites have a dual camera with a long focal length and a dual frequency accurate orbit determination capability.
