The Mobile User Objective System (MUOS) satellite communications asset completed critical design reviews (CDRs) for all segments of the ground system as well as terminal waveform software, General Dynamics Corp. [GD] announced.

This gear will be provided to Lockheed Martin Corp. [LMT], prime contractor for the MUOS program.

The MUOS ground system features ground transport and infrastructure, and network management including a geolocation element and satellite control.

The MUOS User Entry (terminal) Waveform Software will be delivered into the Joint Tactical Radio System (JTRS) library for future porting to radios being developed under the JTRS program, according to General Dynamics.

MUOS will enable secure, end-to-end communications for the warfighter on-the-move via MUOS-compatible terminals communicating with MUOS satellites.

The satellites provide both Wideband Code Division Multiple Access (WCDMA) and legacy Ultra High Frequency Follow-on (UFO) payload communications capabilities, providing both a significant increase in capacity with the WCDMA payload and continuity of legacy UFO communications.

Satellites provide communications with ground terminals and enable connection to the Global Information Grid.
