The US Navy’s fifth Mobile User Objective System (MUOS) satellite has successfully deployed its arrays and antennas after reaching operational orbit.
The MUOS programme is being operated by the Navy's Program Executive Office for Space Systems, located at the Space and Naval Warfare Systems Command in San Diego, US.
Launched in June this year, the MUOS team elevated the satellite to an operational orbit and then deployed the satellite's solar arrays and antennas.
Navy Communications Satellite Program Office programme manager Captain Joe Kan said: "We are very proud of the commitment our team members demonstrated.
"Working together with industry, we were able to execute an alternative propulsion method to manoeuvre MUOS-5 to reach a position that is operationally suitable."
The MUOS-5 satellite experienced a failure of its orbit raising propulsion system following its launch, which stalled the satellite's transfer orbit manoeuvre to its geosynchronous test orbit.
The safety and stability of the satellite was restored by the MUOS team while they probed the fault and examined available options.
The satellite is now scheduled to undergo on-orbit testing, following which it will complete five-satellite MUOS constellation.
MUOS principal assistant programme manager commander Jason Pratt said: "The system will undergo on-orbit testing before final acceptance of the system by the Navy and offering it up for operational use.
"The satellite and its payloads will go through rigorous tests with our ground systems and terminals to make sure everything operates properly."
The MUOS system has been designed to improve communications capabilities by providing 3G-like cellphone communications around the world.
