Improved AFSCN FCT Simulator

ABSTRACT: This Phase I Proposal addresses the need for an innovative, cost-effective approach to performing Air Force Satellite Control Network (AFSCN) compatibility testing of satellites at the factory integration facility. Factory Compatibility Testing (FCT) is not required by Air Force Space Command (AFSPC), but is highly recommended. FCT verifies AFSCN ability to command and control a satellite prior to shipment to the launch base. Current FCT is performed by the Transportable Space Test and Evaluation Resource (TSTR), a system originally designed to function as a replacement AFSCN remote tracking station (RTS) in the event of an RTS failure or maintenance outage. The TSTR system is prohibitively large and expensive to ship to satellite factory locations and requires specialized expertise to operate. A compact FCT system, using advanced signal processing technologies and identical in function to AFSCN ground stations, would provide significant benefits to all AFSCN-supported space programs. Early compatibility issue detection is highly desirable--elimination of these issues at the contractor facility can be accomplished in an efficient manner given on-site availability of satellite-specific engineering expertise and specialized test equipment. An advanced FCT system could save significant satellite pre-launch test costs and would free up critical AFSCN hardware and personnel. BENEFIT: By greatly reducing or eliminating hardware and driving equipment requirements into the digital domain, satellite command and control can be performed from virtually any location with small, highly capable systems. With the appropriate systems engineering, advanced technologies-based satellite command and control capabilities can be incorporated into a new generation of transportable remote tracking station systems capable of deployment to any location with relative ease compared to current transportable systems. These next generation ground stations could provide much needed support to operationally responsive space capabilities that support the warfighter. Extensive networks for satellite control can be established for a fraction of the cost previously seen in networks like the AFSCN. Potential commercial applications of the technologies demonstrated in this effort include the potential for small, low cost transportable satellite command and control ground stations.
