The objective of the ATS-F/Nimbus-E tracking experiment, the first of its kind, is presented. Specifically, this experiment has a twofold purpose: first, to gain experience in the practical use of satellite-to-satellite range and range rate data for very accurate orbit determination (this was its original intent); and second, to evaluate the real usefulness of such a technique for geodetic studies despite the fact that the 1000-km Nimbus orbit is not ideally suited for such a purpose. The accuracies of the tracking systems of the satellite-to-satellite and satellite-to-ground link (ATS-F to the Rosman, N.C. ground station) will be about 0.035 cm/sec in range rate and about 1 m in range - utilizing a 10 sec integration time. With these values it is possible to obtain, based upon performed error analyses, orbit height errors of the order of 0.1 to 0.3 m for the near earth orbiting Nimbus spacecraft. This experiment will therefore hopefully prove to be a significant first step for future earth applications spacecraft carrying altimeters systems for measuring ocean height variations.
