== Overview ==<br />
The Attitude package of the PATRIUS library has been developed according to the SIRIUS Scope Statement '''[A1]'''. The themes developed are described hereafter :<br />
<br />
; Directions<br />
: Implementation of directions of space that can evolve in time.<br />
<br />
; Attitude laws<br />
: Several attitude laws are available. These laws were originally designed for orbit determination needs: in order to broaden their applications, a wrapper object has been created to meet the spacecraft attitude field needs.<br />
<br />
; Attitudes sequence<br />
: Implementation of an attitudes sequence for orbit determination: it is possible to define an attitude law as a series of attitude laws in the context of a propagation.<br />
<br />
; Attitude legs sequence<br />
: Implementation for spacecraft attitude field of an attitude sequence: it is possible to define an attitude leg as a series of attitude legs.<br />
<br />
; Attitude composition<br />
: Implementation of an object that enables to define an attitude law as a composition of several laws.<br />
<br />
; Orientation<br />
: Orientations are similar to attitude providers except that it returns only one angle.<br />
<br />
; Slew<br />
: Implementation of slew. Slews are used in the attitudes sequence to define the transition between two laws.<br />
<br />
; Kinematics<br />
: Implementation of a tool box for kinematics calculations.<br />
<br />
; Guidance command<br />
: Implementation of the ground and the on-board guidance commands. The first one is computed, the second one is simulated. In both cases, it should be possible to compute the guidance command from a law and to consider the guidance command itself as a law.<br />
