MUOS (Mobile User Objective System) is a new military communications system. MUOS will give military users cell-phone-like capabilities anywhere in the world. Four communications satellites operating in 36,000 kilometer stationary (geosynchronous) orbits provide superior satellite phone service that is also encrypted and capable of working despite being in forests or most buildings. In effect, MUOS can replace cell phone towers in any area on the planet once the signals from one of the four satellites are aimed at the area of operations. The complete system is supposed to be active by 2016. The first satellite went up last February. The four ground stations (one for each satellite) are in Sicily, North America, Hawaii, and Australia.
