General Dynamics Releases MUOS 3.1.5 Waveform for USN DMR

Approved by US Strategic Command for Expanded Operational Use

A team led by General Dynamics Mission Systems (GDMS) has successfully tested and released the updated Mobile User Objective System (MUOS) WFv3.1.5 waveform for the US Navy’s (USN) software defined Digital Modular Radios (DMR).

The new waveform is software that adds the MUOS capability to software-defined DMR radios and improves secure voice, video and data communications across the MUOS satellite communications (SATCOM) network. The network was recently approved by the US Strategic Command for expanded operational use. DMR is a four-channel radio and the USN’s communications hub for surface ships, submarines and shore-based communications. As a multi-channel radio, it simultaneously communicates with a wide spectrum of tactical radios and can communicate information at different security levels. Each channel operates independently, allowing USN communication officers to communicate simultaneously with a wide variety of tactical radios used by the military.

“There are more than 700 DMRs in the Navy’s radio inventory, it is one of the largest number of fielded, tactical radios capable of connecting to the MUOS network,” explained a GDMS spokesperson, Carol L. Real. “DMR is one of the first US military radios to use the MUOS waveform and other over-the-horizon waveforms, including Ultra-high Frequency (UHF) SATCOM waveform simultaneously, without interfering with radio communications on other DMR channels.
