N2 - Drag modeling is the greatest uncertainty in the dynamics of low Earth satellite orbits where ballistic coefficient and density errors dominate drag errors. This paper examines fitted drag coefficients found as part of a precision orbit determination process for Stella and Starlette from 2000 to 2004, GEOSAT Follow- On (GFO) from 2000 to 2002 and 2005, and GFZ-1 from 1995 to 1997. The drag coefficients for the spherical Stella and Starlette satellites are assumed to be highly correlated with density model error and are converted to density model corrections.
