The high-frequency (HF) comms for the US Navy's four-channel AN/USC-61(C) Digital Modular Radio (DMR) is about to receive modification from General Dynamics Mission Systems, a business unit of General Dynamics (NYSE: GD).
The company's 3G High-frequency 3rd Generation Automatic Link Establishment (ALE) increases transmission rates from radio to radio by 24 percent and reduces static and other noises that hinder clear, crisp voice communications quality. The ALE also improves communications among US and coalition forces and can supplement satellite communications (SATCOM) when such networks are overloaded or unavailable.
The General Dynamics' software-defined DMR radios are the Navy's mission critical communications hub for Navy vessels and submarines. They provide a wide spectrum of military voice and data communication channels, including Ultra-High Frequency satellite networks, Very High Frequency and Line of Sight radios, single-channel Ground and Airborne Radio Systems (SINCGARS) and other tactical radios. The radios are also equipped with General Dynamics Advanced Infosec Machine (AIM) encryption chip, certified by NSA to carry classified information at the Type 1 - Top Secret level and below. The radios also communicate simultaneously at multiple levels of security, on each of the radio's four channels.
The MUOS waveform was recently added to DMR to significantly enhance the Navy's Beyond-Line-Of-Sight (BLOS) voice and data communications by connecting to the new Mobile User Objective System satellite communications network.
