The United States Army ordered new kits from General Dynamics worth $5 million to upgrade 100 Handheld, Manpack, Small Form Fit (HMS) AN/PRC-155 two-channel Manpack radios. These devices allow them to communicate with the Mobile User Objective System (MUOS) satellite communications system of the Army. The upgrade comprises of a field-replaceable power amplifier and supporting software, which will enable a secure voice and data communication with the MUOS system. The kits are said to be delivered in the fall of this year.
The two-channel PRC-155 manpack radios, which runs the essential waveforms from the defense department library, will enable U.S soldiers to access the MUOS system wherever they are deployed -- either land, sea or air. The waveforms include the Soldier Radio Waveform (SRW) that connects dismounted soldiers to the network, the Wideband Networking Waveform (WNW) that transports huge amounts of data, and the legacy SINCGARS waveform used for communication with existing radios.
With the help of PRC-155’s two-channel capability, soldiers who are operating under any of these waveforms can interconnect with soldiers using another waveform on the second channel. A network of soldiers have the ability to be interconnected with others in a far, remote location, thanks to the MUOS capability in the PRC-155.
In a statement, General Dynamics C4 Systems President Chris Marzilli said, “By upgrading fielded PRC-155 radios, the Army will greatly enhance soldier effectiveness by providing a tenfold increase in SATCOM capacity for secure, over-the-horizon military communications. MUOS access on the two-channel PRC-155 will also allow current Army networks to be bridged and extended far beyond their current reach.
