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

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.<br />

== Overview ==<br />
The following themes are discussed in this section:<br />
<br />
; Physical models<br />
: This chapter describes the force models available including but not limited to : central body attraction, third body attraction, atmospheric pressure, solar radiation pressure, new atmospheric models, terrestrial and ocean tides, other radiative pressure and interplanetary models. It also includes a description of the model describing the displacements of reference points due to the effect of the solid Earth tides.<br />
<br />
; Propagation<br />
: 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.<br />
<br />
; Multi Propagation<br />
: This chapter deals with the multi propagator that is available in PATRIUS to propagate several initial states. Numerical propagator is implemented.<br />
<br />
; Ephemeris<br />
: Integrated ephemeris, Ephemeris and Lagrange ephemeris.<br />
<br />
; Measures and data filtering<br />
: This chapter describes the basic concepts of localisation measures and orbit restitution, measure modelling and data filtering.<br />
