Covariance as an estimator of orbit prediction error growth for geosynchronous orbits Conference Paper uri icon

abstract

  • The performance of covariance, as calculated by the Least Squares Differential Correction process, for predicting error growth for geosynchronous orbits is investigated. This analysis is performed for the analytic propagator, PPT3, and special perturbations. All observations, not just optical, are included in the analysis. The satellites selected for analysis are non-operational satellites to insure that there were no orbit adjusts during the fit spans.
