Abstract Catalog maintenance for Space Situational Awareness (SSA) demands an accurate
and computationally lean orbit propagation and orbit determination technique to cope with …

Semi-analytical orbit propagation methods combine the advantages of analytical and
numerical methods to achieve an excellent balance between efficiency and accuracy. The …

The merits of a perturbation theory based on a mean-to-osculating transformation that is
purely periodic in the fast angle are investigated. The exact separation of the perturbed …

A second-order closed-form semi-analytical solution of the main problem of the artificial
satellite theory (J 2 contribution) consistent with the Draper Semi-analytic Satellite Theory …

In recent years, with the reduction of the cost of microsatellites, the development of
commercial rockets and the multi-satellite launching technology, the construction of large …

STORM is a general semi-analytical propagation code developed at Airbus Defence and

Space agencies generally use numerical methods to meet their orbit determination needs.
Due to the ever increasing number of space objects, the development of new orbit …

The migration of the Fortran-77 DSST Standalone implementation of the Semi-analytical
Method of Orbit Computation (SMC) code to the C/C++ platform is described. The aim is to …

The original development of The Draper Semianalytic Satellite Theory (DSST) was carried
out in Fortran 77; both primary implementations of the DSST (in the R&D GTDS Orbit …

This research work focuses on the selection, development and testing of orbit prediction and
orbit determination methods: the selection is carried out for the purpose of space object …
