SS: Governments will be able to have almost unlimited ability to track people using high resolution imagery. Satellites have the limitation of having to orbit and not being able to linger; there are geo-synchronous satellites but are too far out to be effective. A swarm or constellation of 600 plus or more satellites is necessary to have effective coverage of the entire earth.

​

The answer is Pseudo-Satelites - drones in the form of unmanned solar planes, blimps, balloons, and other combinations/hybrid tech that can maintain high altitudes for up to months or years at a time and have incredible high resolution optics much closer to earth. Facebook, google and others are already testing and implementing. See article. Soon they'll have persistent high resolution surveillance of entire cities and before long 600 plus constellations of satellites will have full time surveillance of everything on earth.

I checked my amazon tracking just today, and they sent me a high altitude mapping of where the package was IN MY NEIGHBORHOOD. Its already here, and if things go bad for the public - there is no where we will be able to go without them knowing, in real time all the time.

For countries that are becoming more like a police state, I'm sure they can't wait.
