Mobile User Objective System (MOUS) On Track for CDR


The Lockheed Martin-led Mobile User Objective System (MOUS) team is on-schedule toward completion of the Critical Design Reviews (CDR) phase in March 2007, where the detailed design of the U.S. Navy’s MOUS is examined, ensuring all requirements are met. The ground system and terminal waveform software developed by team member General Dynamics C4 have recently passed the CDR for all segments of the ground system as well as the terminal waveform software to be inserted into waveform libraries to be used in future JTRS radios. When fielded, MOUS will establish the U.S. military’s next-generation narrowband global mobile satellite communications system.

User terminals will be provided to the U.S. military under the Joint Tactical Radio System with an emphasis on handheld units. The MUOS system will provide familiar cell phone-like services with the satellites acting as “towers” in space, enabling warfighters on the ground to communicate directly with each other and their commanders virtually anywhere in the world. When the system is deployed, MUOS terminals will be communicating with MUOS satellites, providing ground combat elements with on-the-move secure end-to-end communications.

he MOUS ground system will feature the ground transport and infrastructure, network management, geolocation services and satellite control). MOUS satellites will employ both Wideband Code Division Multiple Access (WCDMA) and legacy Ultra High Frequency Follow-on (UFO) payload communications capabilities, providing a significant increase in capacity with the WCDMA payload and continuity of legacy UFO communications. The satellites will provide communications with ground terminals and enable connection to the Global Information Grid (GIG). The Navy’s Program Executive Office for Space Systems and its Communications Satellite Program Office are responsible for the MUOS program.
