AprizeSat
AprizeSat is an American micro-satellite platform for low Earth orbit communications satellites. It is marketed as a low-cost solution, with a claimed cost of US$1.2 million per satellite for a 24-to-48-satellite constellation.[1] As of 2014, twelve spacecraft based on the Aprize bus have been launched.[2]

gollark: Huh, I checked the Minitel L3 protocol docs and it apparently does rednet-style "routing" too.
gollark: See, that's very not ideal.
gollark: You don't have an accurate map, though, and you have devices which might randomly be moving around, or ones which drop out unexpectedly, or ones which can't hold much of a routing table due to limited RAM, or ones which are doing evil things.
gollark: It's not *just* a graph thing. If you had an accurate map of all the network connections it would be a relatively easy thing to route between nodes.
gollark: I heard that general mesh-network routing was extremely hard, so I ignored it and implemented something really stupid instead.
