Featured Product – Jilin-1 Imagery – 3 More 75-cm Satellites Added to Image Hunter!

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!

May 2023 UPDATE! CG Satellite continues to invest in their 75-cm resolution satellite constellation. In late April, they added three more GFD03 series satellites with 75-cm resolution panchromatic bands and 3-meter resolution multispectral bands to their API. The Jilin-1 constellation is still going strong and will continue to provide high-frequency data for years to come.

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.
