| − | == 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.
