Overview

Mobile User Objective System (MUOS) is a tatical Communications satellite which is designed to improve Ground Communications for the US Armed Force[9][10]

MUOS-5 arrived at Cape Canaveral on 9 March 2016.[11] Launch was originally scheduled for on 5 May 2016, but due to an internal investigation into an Atlas V fuel system problem during the Cygnus OA-6 launch on 22 March 2016, the scheduled date was pushed back.[12] The launch took place on 24 June 2016, at 14:30:00 UTC.[13] An "anomaly" aboard the satellite occurred a few days later, however, when it was still in a Geostationary Transfer Orbit (GTO), leaving it "Reconfigured into Safe Intermediate Orbit", or stranded in GTO.[14][15] Amateur observers tracked it in an orbit of approximately 15,240 × 35,700 km (9,470 × 22,180 mi) since 3 July 2016.[16] On 3 November 2016, the Navy announced that the satellite has finally reached operational orbit.
