The Subcommittee on Aviation, chaired by U.S. Rep. Tom Petri (R-WI) held a hearing to review the Global Positioning System (GPS) as a critical part of transportation infrastructure.
GPS is the global navigation satellite system (GNSS) that provides position and timing information at any place on the globe with a high degree of accuracy. The use of GPS in the aviation industry benefits safety and efficiency by providing highly reliable information when compared to the 1950’s era based technology currently in use. GPS will soon replace radar in the primary surveillance method, and the Department of Transportation (DOT) and the Federal Aviation Administration (FAA) already utilize GPS technology in a broad variety of surveillance, navigation, safety, and efficiency applications.
