Abstract

While developing precision orbit ephemeris (POE) derived densities for GRACE and CHAMP, several periods have been found when the correlation between the POE derived density and accelerometer derived density is very low. The primary time period where this occurs is from October 2005 to January 2006 for GRACE. This time period includes the maneuvers required for the GRACE satellites to switch positions, but extend well before and after this event. The low correlations also exist between HASDM and accelerometer derived densities for this time period. This paper characterizes these time periods and attempts to explain the anomalous behavior.
