Introduction

Copernicus.jpg
I shall now recall to mind that the motion of the

heavenly bodies is circular, since the motion
appropriate to a sphere is rotation in a circle.

Mikołaj Kopernik (1473 – 1543)


This section is a short presentation of the orbital tools implemented in the PATRIUS Library. The orbital tools of the PATRIUS library cover the software requirements given in [A1] §13,17,18,20.

This chapter deals with the different propagators that are available to propagate the initial state of a spacecraft. Analytical propagators are implemented (Keplerian, Eckstein-Hechler, 2D, etc.) as well as numerical ones (that are better suited to perform more accurate propagations - it is the most important part of the Patrius library) and STELA semi-analytical propagator.

This chapter deals with the multi propagator that is available in PATRIUS to propagate several initial states. Numerical propagator is implemented.
Ephemeris
Integrated ephemeris, Ephemeris and Lagrange ephemeris.
Measures and data filtering
This chapter describes the basic concepts of localisation measures and orbit restitution, measure modelling and data filtering.
