The Jilin-1 Advantage

92-cm Nighttime Color Imagery
Jilin-1 is one of the few satellites collecting color 92-cm imagery on the dark side of the planet, lending a unique perspective of Earth.

High-Resolution Red Edge Band
Five Jilin-1 Video satellites collect 3.68-m red edge spectral data which provides valuable insights for vegetation mapping projects.

120-Second Video Mode
Jilin-1 Video satellites also collect high-definition 92-cm color video at a rate of 10 frames per second for up to 120 seconds.

Frequent Revisits
The entire high-resolution Jilin-1 constellation revisits the same location up six times a day at 72-cm to 1.06-m resolution.
Overview & HistoryJilin-1 SpecificationsPricing

Built and operated by CG Satellite, Jilin-1 is a constellation of thirteen (as of August 2020) high-resolution satellites launched from 2015 to 2020. These satellites offer a variety of resolutions, collection capabilities, sensors and spectral bands to meet an array of use cases, including video, nighttime imaging and red edge spectral data.

The Jilin-1 constellation features the only known commercial satellites to collect both 92-centimeter (cm) color nighttime imagery and high-definition video. With night imagery at 92-cm resolution and in natural color, the Jilin-1 Video Series is an ideal solution for studying light pollution, population, change detection and illegal fishing.

Launched in 2015, the first Jilin-1 Optical series satellite collects the constellation’s maximum resolution imagery at 72-cm panchromatic and 2.88-meter (m) 4-band multispectral (i.e. blue, green, red and near-infrared [NIR]). Since 2019, CG Satellite has launched four GF and KF series Jilin-1 satellites with 75-cm to 1.06-m resolution into orbit. These satellites are differentiated by their massive swath widths at 42-km for GF02 sensors and a ludicrous 136-km for the KF series.
