This was sufficiently close in timing that I wasn't sure for a moment whether this was just an early caught April Fools.

Then again, the more I think about it, the more this makes sense. Satellite business is hard and capital intensive enough as it is, for starters in the micro-satellite business it would be absolutely prohibitive to run their own hardware just to receive those signals.

Honestly, this is simply sci-fi to me. The fact that we have companies providing satellite communication infrastructure, just extremely futuristic. Am I just too slow with the catching up?

i mean we have been getting porn from space since like the 80's right?

> You can use radar satellite imagery of your various business facilities such as parking lots, logistic centers, and retail stores Could this be used to monitor someone's home?

Monitor their home? No. Imagery from space is only on a 90 minute interval and clouds get in the way. See digitalglobe.com for pricing. It's about $5k per square km iirc.

(With more satellites you can get more frequent coverage of course.)

Radar of course is weatherproof but again the cost is ridiculous unless you are a government or Exxon.

Truly miraculous!

Earlier quoted context omitted.

Surveillance satellites aren't normally in geostationary orbits either, as that's too far away for the optics. Your deltav comment alludes to it. They seem to be into highly elliptical orbits.

You would need an insane amount of LEO satellites in order to get a feed which was continuous. I don't even know how to start doing the maths on this one.

Well, you're not going to be able to make out a house from 100x farther away either.

Thanks to Trump's inability to not tweet anything he sees, we know that Block 4 KH-11 satellites have a 10cm/pixel about standard (they're in an elliptical orbit, but they use which ever is closest at the time). So we're looking at a 10M/pixel in geostationary orbit, assuming you can get the same optics that NROL was shipping up as late as 2013.
