Global Positioning System

The ground antennas are also used to transmit commands to satellites and to receive state-of-health data telemetry. The GPS Program Office is working to enhance many of the capabilities provided by the current satellite based position and navigation equipment. In April, the pre-operational broadcast of navigation messages began for additional civil signals L2C and L5.

Applications such as mapping, aerial refueling and rendezvous, geodetic surveys, and search and rescue operations will benefit from these enhancements. Click was almost one-fourth of the total 29, Global Positioning System, bombs and missiles coalition forces released against System targets.

GPS Positioning to fill Global crucial role in air, ground and sea operations guiding countless service members and equipment to ensure they are on time and on target. General Characteristics Primary Function: Positioning, navigation, timing and velocity information worldwide Primary Contractors: Block IIA, inches 3.

It can be reached at24 hours a day, days a year. Current as of November Point of Contact: Like so many other high-tech developments, GPS was designed by the U. In the Magellan Corp. At first, the military did not want to let civilians use GPS, fearing that smugglers, terrorists, or hostile forces would use it.

Finally, bowing to pressure from the companies that built the equipment, The Defense Department made GPS available for non-military purposes, with some restrictions. On May 1,President Clinton lifted the restrictions, and announced that the option to degrade civil GPS signals during emergencies would be phased out by The federal government is committed to providing GPS technology for peaceful uses on a worldwide basis, free of charge.

GPS satellites have atomic clocks on board to keep accurate time. General and Special Relativity however predict that differences will appear between these clocks and an identical clock on Earth. General Relativity predicts that time will appear to run slower under stronger gravitational pull — the clocks on board the satellites will therefore seem to run faster than a clock on Earth.
