Summary

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 73.

This book combines a presentation of the remarkable progress that has been made in techniques for determining the exact positions of satellites, with an account of the basic science of the atmospheric environment affecting both satellite trajectories and position measurements. Recent outstanding advances make it possible to measure spacecraft and ground point positions with accuracies of the order of a few centimeters or better. Such measurements are of growing importance in navigational applications as well as in many related problems such as gravitational field determinations, sea surface topography, earth crustal movements and studies of earth rotation.
