Jilin-1
Part of the Jilin-1 constellation, the KF01B satellite provides high-resolution Earth observation with both panchromatic and multispectral imaging capabilities.
Technical specifications
What you can do with Jilin-1
Detail at 50cm GSD
At 50cm GSD, vehicles are countable, and building outlines, road furniture and single trees stay distinct. The panchromatic band carries that geometry, and the 2m GSD multispectral bands are pansharpened against it, so colour products hold the same detail.
Standard index bands
Blue, green, red and near-infrared cover the everyday products: true colour, colour infrared, and the indices built from red and near-infrared (NDVI) or green and near-infrared (NDWI). Those index rasters carry the 2m GSD multispectral sampling, not the 50cm GSD panchromatic figure.
10 satellites collecting
10 satellites fly this specification, so there are more chances of a usable pass inside a tasking window and a deeper archive to search before anything is tasked. As stated by the supplier: Up to six revisits per day. That is the cadence to plan against; a cloud-free result usually takes more than one opportunity.
Wide strips
The swath is 150km at nadir, so a large area of interest is covered in few strips. Fewer strips means fewer joins to match, and less time spread across one delivery.
