Abstract

Orbit determination and prediction for low Earth orbit satellites depend highly on atmospheric density modeling. This paper examines the effects of ballistic coefficient errors in using precision orbit e phemerides (POE) as measurements to estimate total density along the satellite orbit. A precision orbit determination process is used to estimate density using Challenging Mini satellite Payload and Gravity Recovery and Climate Experiment precision orbit data. The paper also examines the simultaneous estimating of density and ballistic coefficient. POE derived densities correlate well with accelerometer derived densities, but density error does have some inverse correlation with estimated ballistic coefficient.
