| == Overview ==
| |
| The Attitude package of the PATRIUS library has been developed according to the SIRIUS Scope Statement '''[A1]'''. The themes developed are described hereafter :
| |
| | |
| ; Directions
| |
| : Implementation of directions of space that can evolve in time.
| |
| | |
| ; Attitude laws
| |
| : 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.
| |
| | |
| ; Attitudes sequence
| |
| : 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.
| |
| | |
| ; Attitude legs sequence
| |
| : Implementation for spacecraft attitude field of an attitude sequence: it is possible to define an attitude leg as a series of attitude legs.
| |
| | |
| ; Attitude composition
| |
| : Implementation of an object that enables to define an attitude law as a composition of several laws.
| |
| | |
| ; Slew
| |
| : Implementation of slew. Slews are used in the attitudes sequence to define the transition between two laws.
| |
| | |
| ; Kinematics
| |
| : Implementation of a tool box for kinematics calculations.
| |
| | |
| ; Guidance command
| |
| : 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.
