Interface IAUPole

  • All Superinterfaces:
    Serializable
    public interface IAUPole
extends Serializable
    Interface for IAU pole and prime meridian orientations.

    This interface defines methods compliant with the report of the IAU/IAG Working Group on Cartographic Coordinates and Rotational Elements of the Planets and Satellites (WGCCRE). These definitions are common for all recent versions of this report published every three years.

    The precise values of pole direction and W angle coefficients may vary from publication year as models are adjusted. The latest value of constants for implementing this interface can be found in the working group site.

      • getPrimeMeridianAngle

        double getPrimeMeridianAngle​(AbsoluteDate date)
        Get the prime meridian angle.

        The prime meridian angle is the angle between the Q node and the prime meridian. represents the body rotation.

        Parameters:
        date - current date
        Returns:
        prime meridian vector

      • getPrimeMeridianAngle

        <T extends CalculusFieldElement<T>> T getPrimeMeridianAngle​(FieldAbsoluteDate<T> date)
        Get the prime meridian angle.

        The prime meridian angle is the angle between the Q node and the prime meridian. represents the body rotation.

        Type Parameters:
        T - type of the field elements
        Parameters:
        date - current date
        Returns:
        prime meridian vector
        Since:
        9.0
