Featured Product – Jilin-1 Imagery – 39 New Satellites Added In Two Months!

Did you see the news that we have a satellite constellation in Image Hunter that offers high-resolution mono, video and nighttime imagery? If not, read on and find out more about this exciting constellation!

FEBRUARY 2023 UPDATE! In the last two months, we added over 475,000 new Jilin-1 images to the Image Hunter database from 39 new Jilin-1 satellites ranging from 30-centimeter (cm) to 75-cm resolution! In February alone, we added in seven new 75-cm 4-band Jilin-1 satellites from the new DP series (these DP satellites are identical to satellites in the GF series). We’re excited to see the Jilin-1 constellation grow at such an unprecedented rate. You can check out all the new images on Image Hunter now.

Apollo Mapping offers high-resolution Jilin-1 imagery from satellites owned and operated by CG Satellite. This partnership unlocks a constellation of multiple satellites in four different series (i.e. Optical, Video, GF and KF) launched between 2015 and now. With a robust archive accessible through Image Hunter, the Jilin-1 product suite includes nighttime, video and mono imagery!

Jilin-1 offers an impressive variety of resolutions from 30-cm to 1.2-m. It’s also the only constellation boasting an array of unique capabilities, like 120-second color video collected at 92-cm and 1.2-m resolution; and 92-cm to 1.2-m color nighttime imagery. Five satellites in the Jilin-1 Video series also collect a 3.68-meter red-edge band for vegetation mapping; while satellites in the KF series collect data with a massive 136-kilometer (km) wide footprint or greater. With so many satellites in orbit, Jilin-1 revisits the same location up to six times a day, resulting in a robust archive filled with large-footprint images.
