Package org.orekit.attitudes

Class FixedRate

java.lang.Object
org.orekit.attitudes.FixedRate
All Implemented Interfaces:
AttitudeProvider, AttitudeRotationModel, EventDetectorsProvider, ParameterDriversProvider
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.
