GPS measurements in the Caribbean

Authors


Abstract

In June 1986 the Jet Propulsion Laboratory (JPL, in Pasadena, Calif.) organized and carried out a series of long-baseline geodetic measurements using Global Positioning System (GPS) satellites to measure plate motion between the North American and Caribbean plates. The GPS technique uses radio signals from a group of navigation satellites placed in orbit by the U.S. Department of Defense. The system is currently capable of measuring baselines of a few hundred kilometers' length within an accuracy of a few centimeters, and further improvements are expected.
