General Dynamics Mission Systems has successfully completed testing and released the updated Mobile User Objective System (MUOS) WFv3.1.5 waveform for the US Navy's software defined Digital Modular Radios (DMR), the company announced on 17 September.
The new waveform software adds the MUOS capability to software-defined DMR radios and improves secure voice, video and data communications across the MUOS SATCOM network. The network was recently approved by the US Strategic Command for expanded operational use.
The four-channel DMR is the navy's communications hub for surface ships, submarines and shore-site communications. As a multi-channel radio, it simultaneously communicates with a wide spectrum of tactical radios and can communicate information at different security levels.
Carol Real, a director of General Dynamics Mission Systems, said: ‘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. DMR is one of the first US military radios to use the MUOS waveform and other over-the-horizon waveforms, including ultra-high frequency SATCOM waveform simultaneously, without interfering with radio communications on other DMR channels.’
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
DARPA’s Mission-Integrated Network Control (MINC) programme was set up to develop an autonomous tactical network and enable critical data flow in contested environments.
Why space is an essential part of modern military capabilities
Defence-secure mixed reality headsets can save hours, or even weeks, of travel time to fix defunct equipment or get subject experts effectively “on-site” where they are needed.
The Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) counter-improvised explosive device (C-IED) and Drone Restricted Access Using Known Electromagnetic Warfare (DRAKE) counter-UAS (CUAS) systems are mounted and dismounted RF jammers.
Adarga’s Vantage information analysis tool is in service with the UK MoD and individual UK forces. It builds on the company’s Knowledge Platform which processes, organises and analyses open source material, as well as information held by the user’s military, security and intelligence services.
