www.sciencedirect.com › article › pii
In this study, we evaluate the impact of orbit modeling strategies on the accuracy of orbit predictions on short (one-day), and long (multi-day) time scales.
In this work, we study the two-week prediction accuracy improvement that can be obtained when adding some smaller forces to our previously developed algorithm.
Space agencies usually employ high-precision orbit propagators (HPOP), which are numerical propagators used in conjunction with precise force models.
