AxesNorthEastDownComputeFixedToNorthEastDownRotation Method (Ellipsoid, MotionCartesian, Int32)

Computes the rotation from the central body's fixed axes to a set of north-east-down axes based on a specified reference point. In these axes, the X axis points toward the local North, the Y axis points toward the local East, and the Z axis points down (opposite the surface normal).

Type: AGI.Foundation.Geometry.ShapesEllipsoid
The shape of the central body.
Type: AGI.FoundationMotionCartesian
The motion of the reference point in the central body's fixed frame.
Type: SystemInt32
The order of the highest derivative to compute. To compute just the rotation, pass 0 for this value. To compute rotational velocity as well, pass 1.

Return Value

Type: MotionUnitQuaternion, Cartesian
A transformation from the ellipsoid fixed axes to north-east-down axes.
