8. NaviForum2007, Shanghai China, Dec. 5-7 2007 8 U.S. Policy History 1978: First GPS satellite launched 1983: U.S. President offers free civilian access to GPS 1996: First U.S. GPS Policy. Established GPS a dual-use system under joint civil/military management 1997: U.S. Congress passes law requiring civil GPS to be provided free of direct user fees 2000: U.S. President set Selective Availability to “Zero” 2004: U.S. President issued U.S. Policy on Space-Based PNT 2007: U.S. President announces Selective Availability will no longer be built into modernized GPS III satellites

9. NaviForum2007, Shanghai China, Dec. 5-7 2007 9 U.S. Policy Principles Provide civil GPS and augmentations free of direct user fees on a continuous, worldwide basis. Provide open, free access to information needed to develop equipment. Improve performance of civil GPS and augmentations to meet or exceed that of international systems. Encourage international development of PNT systems based on GPS. Seek to ensure international systems are interoperable with civil GPS and augmentations. Address mutual security concerns with international providers to prevent hostile use. Outlined in 2004 Presidential Policy on Space-Based Positioning, Navigation, and Timing (PNT)
