A -- SECOND CIVIL FREQUENCY ON GPS BLOCK IIF SATELLITES--SOURCES SOUGHT SOL DTOS59-96-R-00006 DUE 121595 POC Contracting Officer, Daniel Telep, Jr., 202/366-6699 The U.S. Dept. of Transportation (DOT), Office of the Secretary, Radio and Navigation Policy Office, is seeking information that could aid in determining the benefits of adding a second civil frequency to the NAVSTAR GLOBAL POSITIONING SYSTEM (GPS) Block IIF satellite constellation system. The procurement (i.e,, RFP, FO4701-95-R-0001) of the GPS satellite is currently being handled by the U.S. Air Force/SMSC/LAAFB/GPSJPO, Captain C. Junker at (310) 363-3586 and Captain J. Stiglich at (310) 363-3214. The Government's goal of adding a second frequency on the GPS Block IIF satellite is to provide increased accuracy for civil users. Furthermore, the additional frequency would be used to provide a more accurate estimate of atmospheric effects on the position estimate, thereby allowing for more accurate solutions. The purpose of this sources sought is to request suppliers of GPS related equipment, (e.g., receivers, monitors) suppliers of related services, users of the system, and any other interested parties to submit any written information they may deem helpful in the conduct of this analysis. The request for information from suppliers, and users of the GPS is identified but not limited to: 1) descriptions of potential applications for which a second civil frequency on the GPS Block IIF satellite would be required or advantageous, and 2) identification of estimated annual revenue and cost changes anticipated as a result of the presence of a second civil frequency on the GPS Block IIF satellite.
