General Dynamics-built Digital Modular Radios Connect with Army PRC-155 Manpack Radio in MUOS Test Lab

The General Dynamics Mission Systems-built four-channel Digital Modular Radios (DMR) successfully completed a Mobile User Objective System (MUOS) satellite communications test at the General Dynamics MUOS test facility in Scottsdale, Ariz. Using the MUOS satellite communications and ground station simulators, the DMR radio successfully completed voice calls and data transmission to and from the DMR to an Army AN/PRC-155 two-channel Manpack radio. DMR is the U.S. Navy's networking radio currently operating on many Navy vessels and on shore locations.

"The success of this test is important because it demonstrates the Navy's work, in collaboration with the Army, to deliver on the promise of the MUOS satellite communications to joint forces worldwide," said Chris Marzilli, president of General Dynamics Mission Systems.

Built using open architecture standards, the DMR radios will continue to provide improved functionality and interoperability while accommodating next-generation communications waveforms such as MUOS, the Integrated Waveform and future advanced network communications waveforms that will be added to the U.S. military's waveform library.

DMR was the first software-defined radio used by the U.S. military. As a digital radio, adding new operating upgrades and enhanced capabilities, like connecting with the narrow-band MUOS satellite network, are completed by software with few hardware changes keeping the radio operationally current and cost-effective for the Navy. There are currently 500 secure, four-channel DMR radios supporting Navy operations worldwide.
