The Global Positioning System Geodesy Odyssey

By Alan G. Evans, Ed. Robert W. Hill, Geoffrey Blewitt, Everett R. Swift, John Bossler and James P. Cunningham


Fundamental to NAVSTAR Global Positioning System (GPS) operation and application are the computational developments that have led to accurate user positioning. This paper discusses some of these developments from a historical perspective. The developmental odyssey begins with the events leading to initial GPS operation. Early developments in satellite geodesy, which led to the GPS constellation development, are briefly reviewed. A chronology of the incremental improvements in satellite orbit determination is presented. Contributions basic to GPS operation and accuracy, including coordinate frame definition and software development for user absolute and differential/kinematic positioning, are reviewed. Applications—including surveying and mapping, geodynamics, and spaceborne geodesy, which have motivated the most stringent accuracy requirements for GPS—are discussed. The paper ends with a discussion of expected future geodetic capabilities and then a summary of the impact of GPS geodesy contributions to the user community
