Mobile User Objective System News

The Navy's fifth Mobile User Objective System (MUOS) satellite has reached operational orbit and has successfully deployed its arrays and antennas. On Oct. 22, the MUOS team raised the MUOS-5 satellite to an operationally-suitable orbit. The team completed a series of deployments of the satellite's solar arrays and antennas, with the last occurring successfully Oct. 30. MUOS-5 launched June 24 from Cape Canaveral Air Force Station and experienced a failure of its orbit raising propulsion system that halted the satellite's transfer orbit maneuver to its geosynchronous test orbit. The MUOS team ensured the satellite remained stable, safe, and under positive control while it investigated the issue and examined options.

The U.S. Navy awarded a contract modification to General Dynamics Mission Systems to build and deliver more than 30 new AN/USC-61(C) Digital Modular Radios (DMR), along with related materials and equipment for new Navy surface vessels and submarines. The software-defined radios are a mission critical communications hub for Navy vessels and submarines. The contract modification exercises the sixth option to a contract awarded to General Dynamics in 2010. A majority of the work will be done at General Dynamics’ Scottsdale, Arizona, location. “This contract demonstrates the Navy’s continuing trust in DMR as it keeps pace with new and innovative communications technology for sailors and their commanders to securely connect with one another anywhere…

After a two-day delay due to tropical storm conditions, the Navy's fourth Mobile User Objective System (MUOS) satellite launched at 6:18 a.m. EDT from Space Launch Complex 41. MUOS-4, whose signal was acquired approximately three hours after launch, completes the initial operational constellation and provides near global network coverage for warfighters and combatant commanders. This array allows mobile forces, including submarines, surface ships and aircraft, to communicate around the world via the narrowband spectrum. User communities that will primarily benefit include ground forces at the individual soldier level but also include members of all services and special forces.

The U.S. Navy has ordered 56 AN/USC-61(C) Digital Modular Radios (DMRs) and related equipment from General Dynamics. The newly built DMR radios will be capable of using the Mobile User Objective System (MUOS) waveform, the digital dial tone needed to make voice calls to the U.S. Department of Defense's next generation, narrowband MUOS satellite communications system. The four-channel radios form the foundation of the Navy's network communications aboard submarines, surface ships and on-shore locations. This order, valued at over $29 million, exercises option five on a contract awarded to General Dynamics in 2010. "DMR is an extremely versatile radio and we continue to update its capabilities to ensure that Navy communications networks have the most advanced and secure technologies…

The Navy's third Mobile User Objective System (MUOS) satellite was launched today at 8:04 p.m. EST from Space Launch Complex 41. This communications satellite will significantly improve capability for Navy and Department of Defense tactical operators. Over the next several days, the satellite will transition to its geosynchronous orbit location 22,000 miles above Earth. Its solar arrays and mesh antennas will then be deployed and on-orbit testing will begin for eventual commissioning into service. Upon acceptance for operational use, MUOS 3 along with MUOS 1 and 2 already on-orbit, will provide communications coverage to more than three-quarters of the globe.

General Dynamics Mission Systems makes its debut as General Dynamics' newest business unit at the Surface Navy Association's (SNA) 27th National Symposium. General Dynamics Advanced Information Systems and General Dynamics C4 Systems combined to form General Dynamics Mission Systems on January 1, 2015. "This restructuring has allowed us to create a real powerhouse. We are stronger together and offer a more robust portfolio of products, services and solutions that help customers successfully execute their missions in today's dynamic environment," said Chris Marzilli, president of General Dynamics Mission Systems. "Our exhibits at SNA highlight our collective capabilities from which the U.S. General Dynamics Mission Systems will deliver greater capability more efficiently.

U.S. Navy military and civilian engineers are preparing the latest military communications satellite for a planned Jan. 20 launch from Cape Canaveral Air Force Station, Florida. The satellite is part of MUOS, or Mobile User Objective System, which operates like a smartphone network from space, vastly improving secure satellite communications for mobile U.S. forces. Unlike its predecessor system, MUOS provides users a global, on-demand, beyond-line-of-sight capability to transmit and receive high-quality voice and mission data from a high-speed Internet Protocol-based system.

General Dynamics C4 Systems successfully demonstrated that the AN/PRC-155 two-channel Manpack radios closed a 2,000-mile communications gap between Phoenix, Ariz., and a second set of users in Taunton, Mass. The successful 2,000-mile transmission of the PRC-155 Manpack radio channels bridged the Line of Sight Rifleman Radio and Single Channel Ground and Airborne Radio System (SINCGARS) radio communications to orbiting Mobile User Objective System (MUOS) satellites. "With the success of this demonstration, General Dynamics successfully demonstrated the promise of the MUOS satellite communications system using PRC-155 Manpack radios. The demonstration also successfully showed how dismounted Soldiers…

A team of scientists from the U.S. Coast Guard (USCG) Research and Development Center (RDC) will depart from Seward, Alaska, for a technology evaluation in the Arctic aboard the Coast Guard Cutter Healy Aug. 8, the Coast Guard announced. According to the USCG, the RDC is leading a multiagency team to support Arctic Shield 2014, a 17th Coast Guard District initiative. The purpose of their month-long evaluation is to improve USCG capabilities in the Arctic region, specifically in the areas of boat operations, communications, navigational safety and oil spill response.

A team of scientists from the Coast Guard Research and Development Center (RDC) is to depart shortly from Seward, Alaska, for a technology evaluation in the Arctic aboard the Cutter 'Healy informs USCG. The RDC is leading a multi-agency team to support Arctic Shield 2014, a 17th Coast Guard District initiative. The purpose of their month-long evaluation is to improve Coast Guard capabilities in the Arctic region, specifically in the areas of boat operations, communications, navigational safety and oil spill response. “The RDC plays a key role in charting the service’s future efforts in the Arctic by evaluating new and emerging technologies for applicability to Coast Guard operations in a harsh and remote environment,” said Capt. Dennis Evans, commanding officer of the RDC.

U.S. Strategic Command (USSTRATCOM) has accepted the first Mobile User Objective System (MUOS) satellite for initial operational use. MUOS is a next-generation narrowband tactical communications system designed to improve communications for U.S. forces on the move. The Naval Satellite Operations Center (NAVSOC) at Point Mugu, Calif., began "flying" the satellite in June. In addition to providing continuous communication for all branches of the U.S. military, Navy delivered space…

CAPE CANAVERAL AIR FORCE STATION, Fla. (NNS) -- The Navy's first Mobile User Objective System satellite was launched Feb. 24 from Space Launch Complex 41. MUOS is a next-generation narrowband tactical communications system designed to improve communications for U.S. forces on the move. MUOS will provide military users simultaneous voice, video and data capability by leveraging 3G mobile communications technology. Born from the need for stable, 24/7 ship-to-shore communication that could be successful regardless of environments and geographical conditions…
