摘要

The problem of correcting atmospheric range error from radiometric measurements is addressed. It forms part of preliminary work for ERS-1. One part of the payload will be a high-accuracy altimeter, one of whose missions will be to perform precise determinations of the geoid and of sea-surface irregularities less than 1 m in height. The altimeter should also be able to measure the surface wind speed with an accuracy of about 2 m/s. For such a mission, the position of the satellite must be known with similar accuracy. It must therefore be tracked continuously by a large set of ground based ranging instruments. In this study, corrections to both ground-based and space-based measurements are dealt with.
