I don't know how big the market is but there is at least one multibillion dollar company (ESRI) in the space. I think they have products targeted at most major industries. The US has at least two government agencies that are heavily involved in satellite imagery and they must contract out a lot of that work. I think it is getting easier to enter into the government contracting space. Anduril shows that you can get VC backing and scale fast if you have the right product.
