Abstract

In this study, a two-stage approach for estimation of spacecraft's position and velocity by single station antenna tracking data is proposed. In the first stage, direct nonlinear antenna measurements are transformed to linear x-y-z coordinate measurements of spacecraft's position, and statistical characteristics of orbit determination errors are analyzed. Variances of orbit parameters' errors arc chosen as the accuracy criteria. In the second stage, the outputs of the First stage are improved by the designed EKF for estimation of the spacecraft's position and velocity on indirect linear x-y-z measurements.
