Using EOP and Solar Weather Data for Satellite Operations

AAS/AIAA Space Flight Mechanics Meeting
AAS 13-373

Vallado, David A. and T.S. Kelso, "Earth Orientation Parameter and Space Weather Data for Flight Operations," presented at the 23rd AAS/AIAA Space Flight Mechanics Meeting, Kauai, HI, 2013 February 10–14.


Earth Orientation Parameter and Space Weather data are critical data elements for numerical propagation and space operations. Since CSSI first began assembling consolidated files of EOP and space weather data, we have tracked the performance of these data to better understand what operational users can expect. We present detailed analysis and results over the last few years to assess the best sources for this data, and recommend options for processing when no data exists. Corrections to space weather data are shown where anomalies exist. Finally, we investigate the implications of space weather prediction accuracy and its effect on satellite lifetime.
