You can rent access to nearly real-time custom satellite targeting for <$3k per image. That means while you're correct that not all countries can afford it, most can.
Planet Labs PBC, a leading provider of high resolution images taken from space, said Friday it would hold back for 96 hours images of Gulf states targeted by Iranian drone attacks.
It did not say if it had acted at the request of US authorities.

To get a naval fix, you usually define an "area of uncertainty" around the last confirmed location of the ship. The area is usually a circle with the radius being the maximum distance the ship/group could travel at full speed.
So, you don't exactly "know" where the ship is, but you can draw a hypothetical geofence around where it's likely to be, and scan that area.
So the satellite can know where the ship is, because it knows where it isn't? Then it's a simple matter of subtracting the isn't from the is, or the is from the isn't (whichever is greater)?
