A Comparison of Nonlinear Filters for Orbit Determination and Estimation (Satellite)

This research compares the performance of three filters when applied to the problem of orbit determination using actual satellite data obtained from ground based radars. The states estimated are the osculating classical orbital elements and the satellite ballistic coefficient. The dynamics used to propagate the state vector forward in time include the two-body acceleration plus perturbations due to atmospheric drag, the zonal harmonics in the geopotential through J(,6), and the tesseral harmonics in the geopotential through J(,44). The atmospheric density model used is an exponential model that includes diurnal variations and variations in the decimeter solar flux. The observations used to update the state vector estimates are slant range, azimuth, and elevation relative to a radar site.
