I wouldn't worry much about satellites putting S&R out of bidnez. The Pentagon and the NSA and the CIA keep all the cool ones to themselves and their satellites are Uber expensive. There's also the problem that you have to wait for the orbital path to intersect the area you need to search; this would be just as true for civilian satellites. Geostationary satellites, like those used for weather and communications, are far too high for detailed ground surveillance.

Rather than satellites, I'd expect remote drone tech to be used and pretty soon at that. They're proliferating and prices are dropping. But a substitute for boots on the ground? I'd guess more of a supplement, at least for now.

Cheers,
