Damocles Alpha
Primary function: Global military communications and navigation system
Primary developer: Protectorate Research and Development Commission
Power plant: Solar panels generating 18 kW, triple-stacked high density nickel-hydrogen batteries
Weight: 6,700kg
Orbit altitude: 42,100 km, geosynchronous
Payload:
Low data rate communications (voice, data, teletype, facsimile) at 75 bit/s to 2,400 bit/s
Medium data rate communications (voice, data, teletype, facsimile) at 5.2 kbit/s to 9.4 Mbit/s
