Comment Re:Signal triangulation = GPS (Score 1) 175

Even without any atmosphere, the diffraction-limited resolution of a 2.5 m optical system watching from a 200 km altitude is limited to ~5 cm. Is that sufficient for reading the plates? (Even that number is only for watching from straight above, which sort of doesn't work for vehicle license plates - Pythagoras then applies for diagonal lines of view.)

Comment Re:Tired of this space obsession (Score 1) 90

What is this obsession with shoving stuff into space? There are already so many satellites in orbit that we'll soon be at a critical point of so much space debris flying around that it'll be self generating and dangerous

Maybe with lower costs, some of this extra stuff could actually take the other old stuff out of the way?
