With the two new software upgrades, the U.S. Navy
has four-times more capacity for secure HF communications without adding
additional hardware or changing the configuration in space-constrained
shipboard radio rooms. The Navy began equipping surface and subsurface
ships and a number of land-based locations with the DMR in 1998, and
there are currently 500 secure, four-channel DMR radios supporting Navy
operations worldwide.
Chris Marzilli, president of General Dynamics Mission Systems, said,
“As the first software-defined radio to be used by the U.S. military,
DMR continues to produce long-term cost-effectiveness for the Navy because
these technology advancements use software, avoiding time-consuming
and cost-intensive hardware replacements.”
General Dynamics engineers are also working to integrate the new Mobile
User Objective Systems (MUOS) waveform into the DMR radios. The waveform
is the digital dial tone needed to connect to the U.S. military’s
new narrowband MUOS satellite communications system. Once the MUOS network
is operational, Navy personnel will experience the global reach, voice
clarity and connection speeds similar to their cellphones they use at
home.
Built using open architecture standards, the DMR radios will continue
to provide improved functionality and interoperability while accommodating
next-generation communications waveforms like MUOS, the Integrated Waveform
and future advanced network communications waveforms.
