Earth Locating Image Data of Spin-Stabilized Geosynchronous Satellites

摘要

Aspects of the GOES system relevant to earth-location are reviewed. The essential features of an earth-location capability that satisfies the needs of users of the data are specified. A mathematical formulation of the geometry and orbit/attitude determinations, including the actual algorithms, is presented. The implementation of these methods on VIRGS is described. Finally, the rationale for a centralized, once-for-all users earth-location service and an error budget with some actual results are presented.
