The current United States policy concerning use, implementation, and control of its Global Positioning System (GPS) global navigation satellite system (GNSS) is focused on autonomous control and oversight. The United States has however, for all intents and purposes, guaranteed that it will provide GPS Standard Positioning Service (SPS) navigational data, free of charge, to the entire world for peaceful, civil use. The United States has further enhanced this commitment by its promise to remove the current Selective Availability (SA) controls from GPS thereby providing worldwide access to the more accurate, non- degraded navigational data. In concert with such assurances, the United States has engaged in a campaign to encourage a universal adoption of GPS and GPS navigational data as the sole satellite source of such data for worldwide air traffic control and management and the myriad of other navigation, positioning, and timing applications made possible by GNSS.
