The Jilin-1 Advantage

92-cm & 1.2-m Nighttime Color Imagery

Jilin-1 is one of the few satellites collecting color 92-cm and 1.2-m 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 and 1.2-m 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 30-cm to 1.2-m resolution.

Overview & History

Jilin-1 is a constellation of multiple high-resolution satellites launched from 2015 and on. 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) and 1.2-meter (m) color nighttime imagery and high-definition video. With night imagery at 92-cm and 1.2-m resolution and in natural color, the Jilin-1 Video and GF03C Series are ideal solutions for studying light pollution, population, change detection and illegal fishing.

April 30th, 2022 marked an important date for Jilin-1 with the launch of GF04A, the first 30-cm resolution satellite to join the constellation. First launched in 2021, satellites in the Jilin-1 KF Optical series collect 50-cm panchromatic and 2-m 4-band multispectral (i.e. blue, green, red and near-infrared [NIR]) imagery with a massive swath width of 136-km or greater. And since 2019, multiple GF Optical series Jilin-1 satellites have launched into orbit with 75-cm resolution and 17-km to 40-km swath widths.
