Abstract : T HIS REPORT IS IN TWO PARTS. Part I presents an approach to the solution of the refraction problem which differs mathematically from our previous one. In principle, this approach permits the calculation of the satellite refraction from the stellar refraction with no knowledge of mu other than the value of mu(o). This approach alsodevelops a correction term for the case where the satellite is within the earth's atmosphere, rather than completely above it. Part II discusses the use of passive satellites (of the 'Echo' type) for use as geodetic tools. While the method is possible, its feasibility is limited by the requirements placed on the ground-based RF equipment and antennas. (Author)
