GD’s AN/PRC-155 MUOS-Manpack radio connects US Navy MUOS network

General Dynamics Mission Systems' (GDMS) two-channel AN/PRC-155 MUOS-Manpack radio has successfully connected the US Navy's Mobile User Objective System (MUOS) satellite network.


General Dynamics Mission Systems’ (GDMS) two-channel AN/PRC-155 MUOS-Manpack radio has successfully connected the US Navy’s Mobile User Objective System (MUOS) satellite network.

During a recently concluded government test of the MUOS satellite network, the radios reportedly transmitted voice and data communications to the on-orbit MUOS satellites.

The demonstration is said to be a part of an army-conducted customer test with the AN/PRC-155 MUOS-Manpack radio running terrestrial waveforms, the Soldier Radio Waveform and the Single Channel Ground and Airborne Radio System waveform simultaneously with the MUOS waveform.

"The PRC-155 Manpack is the only army-fielded radio available to the US today."

Coupled with the navy MUOS operational tests, the demonstration is deemed to measure the functionality of the waveform across the services.

General Dynamics Mission Systems vice-president and general manager Mike DiBiase said: "As part of the Handheld, Manpack and Small Form Fit (HMS) family, the PRC-155 Manpack is the only army-fielded radio available to the US today.

"These radios connect the new MUOS network, bridging lower-tier tactical networks like the soldier radio waveform and SINCGARS radios to the big army network, reaching back to army personnel located in the most austere locations."

Built by Lockheed Martin, the MUOS satellite communications network aims to promote secured, robust data communications for the US Department of Defense and government personnel.

The PRC-155 MUOS-Manpack radio is equipped with a high-power amplifier that provides the radio-signal strength required to be transmitted to the MUOS satellites that are in geo-synchronous orbit above the Earth’s equator.

Leveraging both the channels, PRC-155 connects different radios and waveforms used by soldiers active in a mission area.

Currently, there are 5,326 PRC-155 Manpack radios employed in the army offering secure line-of-sight and satellite communications connectivity for Army personnel deployed in places where other communication networks are inaccessible.
