B -- REQUEST FOR INFORMATION DUE 043098 POC Maj. (Sel) Dawson Oslund, SMC/XRIC, (310) 363-0799 WEB: click here to obtain GPS background information, http://www.laafb.af.mil/SMC/CZ/homepage/. E-MAIL: click here to contact the action officer via e-mail, Dawson.Oslund @losangeles.af.mil. The Air Force is seeking ways to augment current GPS service with improved satellite navigation signals for civil and military users. To this end, the Air Force is interested in concepts that define candidate system architectures for GPS augmentation. The concepts may include use of commercial and modified commercial space assets, as well as current GPS satellites. The proposed solutions will be considered in the current GPS Modernization decision process. We are looking for descriptions of augmentation concepts to satisfy current and anticipated radio-navigation deficiencies and required civil and military capabilities over and above the current GPS service, baselined at 21 satellites. As this is a short-notice RFI, the information required is conceptual. We are seeking concepts to satisfy critical civil needs for precision navigation and precision exploitation including the world-wide civil-aviation precision-approach Category I service with the 6-second signal integrity message and synchronized time service coordinated with the current GPS reference time maintained at the master control station. The space augmentation concepts must be cost-effective, quick to IOC in 2002 to 2005, compatible with the existing GPS signal structure, and capable of providing at least three civil signals in L-band (the current L1 and L2, plus an additional signal). Concept papers should include descriptions of functional or performance needs being met or addressed, candidate systems and architectures, operational concepts, critical technologies, feasible business arrangements, proposed operational dates, and rough-order-of-magnitude price. Concept description papers should be submitted NLT 30 Apr 98. This call is open to all space-related companies interested in providing this type of capability or service. The GPS Joint Program Office (http://www.laafb.af.mil/SMC/CZ/homepage/) and US Coast Guard (http://www.navcen.uscg.mil/gps/) web sites contain a wealth of GPS background information. All submitted concept descriptions will be reviewed by a small Air Force team from SMC, AFSPC, and Aerospace Corporation . This call is for information purposes only. The government does not intend to award any contracts based on this action or to pay any costs associated with this information. Proprietary information will be protected accordingly.
