National Strategic Satellite Communications System (NSSS)

In 2001 Program Decision Memorandum (PDM) IV directed the initiation of two new Satcom systems: the National Strategic Satellite System; and the Advanced Wideband System. It also called for the development of laser communication technology, and directed a comprehensive study (the Transformational Communication Study).

In July 2002 SI International received a four and one-half year, $1.9 million award to provide technical, engineering, and consulting services in support of the Headquarters Air Force Space Command (AFSPC) Military Satellite Communications Systems Division.

As the prime contractor, SI International supports the transition and conversion from current satellite communication systems to Advanced Extremely High Frequency (AEHF) and the National Strategic Satellite Communications System (NSSS). SI International will provide technical analysis, consulting and engineering assistance services in support of AFSPC; guidance on the Transformational Communications Study (TCS); and, transition and terminal interoperability analysis for the NSSS Implementation plan. Specifically, SI International will develop a NSSS network transition plan highlighting critical paths and design a satellite communications system transition database.

The experience and expertise gained during the AEHF program transition effort aids in the development of the TCS Transition Plan. Initiatives within the TCS have put forward a proposed NSSS that would combine worldwide and polar coverage to access satellites with an all in one communications system.

SI International will leverage its broad range of satellite communication knowledge to provide a prioritized plan of action to transition today's numerous satellite communication systems networks and users to a single National Strategic Satellite Communications System.

Subsequently, this construct faded from view, and by 2005 the status of the enterprise was quite obscure.
