There are many of them already in orbit. The U.S. Army is the first customer and they will probably be happy with any satellite better than what exists today. Have SpaceX published any performance metrics? Jitter, Latency, Loss, Throughput per {n} users, etc... Do they use forward error correction? Do they observe QoS settings, 0x04, 0x08, 0x10 at least? I would love to be an early adopter if the transceivers are not too expensive.
