AN/PRC-155 Manpack radios operating from Alaska and the Arctic Circle made voice and data calls using the Mobile User Objective System (MUOS) waveform and satellite network, according to manufacturer General Dynamics C4 Systems.
Communications between users at high latitudes and MUOS satellites in geosynchronous equatorial orbit are difficult. But the PRC-155 was able to make calls from fixed sites in Alaska as well as aircraft flying in the Arctic Circle.
“Exposed to sub-freezing temperatures and blistering arctic winds, the PRC-155 Manpack radio is the first and only military radio to deliver secure voice and data connectivity with the MUOS system from the highest latitudes on the planet,” said General Dynamics C4 SystemsPresident Chris Marzilli. “The success of this demonstration proves that with a MUOS-capable PRC-155 Manpack radio, soldiers operating in extreme and isolated locations will always be connected to the Soldier’s Network.”
