18 -- SPACE VEHICLES -- GLOGAL POSITIONING SYSTEM (GPS) MODERNIZATION -- CIVILIAN SOL DTTS59-97-SOURCES DUE 051597 POC POC Daniel Telep, Jr. Contracting Officer, 202-366-4952 WEB: NA, NA. E-MAIL: na, hskalski@spacecom.af.mil;. Global Positioning System (GPS) modernization -- Civilian requirements definition. Contact Hank Skalski, Department of Transportation (DOT) Civil GPS Liaison, (719)554-2570. The government is conducting a Sources Sought for civilian sector input to the GPS modernization process. This announcement is not a Request for Proposal and will not directly lead to any solicitation; it is a request for information relating to the identification of civil requirements for the modernization of GPS. GPS is a dual use (military and civil) space-based radionavigation system, providing navigation, positioning, and timing services. The US Air Force has begun an effort to develop a Future Worldwide Positioning, Navigation, and Timing System Capstone Requirements Document (CRD) to address the near, mid, and far term modernization of the GPS. The CRD is an over-arching document that will identify performance-based, operational requirements" that address military and civil navigation, positioning, andtiming needs for GPS or future space-based navigation systems. The Air Force requested DOT to coordinate the civil sector CRD input. The requirements in the CRD will be reviewed and ranked to develop an Acquisition Master Plan. This request for information seeks data related to the formulation of the civil performance-based, operational requirements which will be used to derive future GPS technical, operational, and management characteristics. Input should consider a system of systems approach and address all segments of the basic GPS, as well as related applications/systems. Submission of data is requested no later than May 15, 1997, and should be made to the attention of Hank Skalski: (mail) US DOT -- HQ AFSPC/DRFN, 150 Vandenberg St., Suite 1105, Peterson AFB, CO, 80914-4590; (e-mail) hskalski@spacecom.af.mil; (fax) 719-554-9604. All inputs should include contact information so DOT can seek clarification when necessary. (0085)
