BIA
Why waste many hours searching a large area with the high-res UAV camera when you can instead discount 98% of it with Sentinel and key the FMV onto the moving vehicles/static vehicles that have arrived since yesterday instead?
The UAV/RPAS carries its own SAR/GMTI with less range than sentinel (about 1/4) but a better resolution (about 3 times) so it can do lots of wide area discrimination.
