4) Global Positioning SystemThe Global Positioning System (GPS) constellation remains healthy, stable, and robust with 31 operational satellites on-orbit providing precise position, navigation, and timing information to civil and military users worldwide. In May 2008, the GPS III contract was awarded to Lockheed Martin for the development and production of two initial SVs, with eight more production vehicles now on contract and options for the production of up to two additional SVs. GPS III SV 01 has been completed and is in storage, with an initial launch capability date set to occur in spring 2018. It will be the first GPS satellite on-orbit with Military Code (M-Code) signals in support of warfighter operations. GPS III will introduce new capabilities to meet higher demands of both military and civilian users. Additionally, it expands international cooperation in the Global Navigation Satellite System (GNSS) arena by fielding the new L1C civil signal interoperable with European Galileo System, Japanese Quazi-Zenith Satellite System, and other GNSS systems. For SV 11 and beyond, the GPS III Follow-On studies are now underway and the plan is to release a request for proposal later this summer.
