In the end-to-end system test of the Mobile User Objective System satellite network, a handheld AN/PRC-155, using the final version of the MUOS waveform, transmitted secure voice and data communications to the orbiting MUOS satellite, through the MUOS ground station and back to a second PRC-155 Manpack radio.
The company said it was the first time that any military radio has communicated with the MUOS space-ground network, "which will ultimately extend the reach of the soldiers' network to even the most isolated locations."
"The PRC-155 is the only government-owned, off-the-shelf radio to demonstrate this capability," said Chris Marzilli, president of General Dynamics C4 Systems. "Using the same cellphone technology that powers commercial smartphones, military and government personnel can make secure 'calls' and exchange critical information from anywhere in the world."
The non-proprietary MUOS waveform used for the test was developed by General Dynamics and delivers voice and data communications at 16-times greater capacity than the military's current Ultra High Frequency satellite communications system, the company said.
The U.S. Army has ordered 3,800 of the radios. Those used in the test are among the first delivered to the service.
