Class FixedRate

  • All Implemented Interfaces:
    AttitudeProvider

    public class FixedRate
    extends Object
    implements AttitudeProvider
    This class handles a simple attitude provider at constant rate around a fixed axis.

    This attitude provider is a simple linear extrapolation from an initial orientation, a rotation axis and a rotation rate. All this elements can be specified as a simple reference attitude.

    Instances of this class are guaranteed to be immutable.
