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 …

The DSST includes comprehensive models for both the mean-element and the short-
periodic motions of an artificial Earth satellite orbit. These models are developed in the …

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 …

Analytical gravity models are included in the equinoctial element formulation of the low-
thrust optimal equations of motion and the adjoint equations for the Lagrange multipliers …

The Draper Semi-analytic Satellite Theory (DSST) orbit propagator can be found in two
forms, as an option within the Massachusetts Institute of Technology version of the Goddard …

The paper presents an open-source orbit determination application based on the Draper
Semi-analytical Satellite Theory (DSST) and a recursive filter, the Extended Semi-analytical …

Abstract GTDS [1, 2, 3, 4] has played a significant role in Space Research: as an orbit
propagation (OP) and determination (OD) suite, as a prototype for subsequent operational …
