All of that, and the funny thing is /that is the easy part/. Moving payloads to space is just incredibly expensive, but not fundamentally hard in the same way that post-launch coordination of satellite constellations and RF tuning to support things like mobile connectivity are (I can connect to Starlink satellites from my iPhone through T-Mobile).

Connecting to a cell phone and/or selling a phased array antenna that can track an object travelling 17,000 mph for $300 is crazy hard.

But a military is going to be fine with an antenna that costs $3000.
