Operational Aspects of CASA UNO '88-the First Large Scale International GPS Geodetic Network
Digital Object Identifier (DOI)
For three weeks, from January 18 to February 5, 1988, scientists and engineers from 13 countries and 30 international agencies and institutions cooperated in the most extensive GPS (Global Positioning System) field campaign, and the largest geodynamics experiment, in the world to date. This collaborative experiment concentrated GPS receivers in Central and South America. the predicted rates of motions are on the order of 5-10 cm/yr. Global coverage of GPS observations spanned 220 degrees of longitude and 125 degrees of latitude using a total of 43 GPS receivers. The experiment was the first civilian effort at implementing an extended international GPS satellite tracking network. Covariance analyses incorporating the extended tracking network predicted significant improvement in precise orbit determination, allowing accurate long-baseline geodesy in the science areas.
