## AxesEastNorthUpComputeFixedToEastNorthUpRotation Method (Ellipsoid, MotionCartesian, Int32) |

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

Syntax

public static Motion<UnitQuaternion, Cartesian> ComputeFixedToEastNorthUpRotation( Ellipsoid shape, Motion<Cartesian> fixedReferencePoint, int order )

- shape
- Type: AGI.Foundation.Geometry.ShapesEllipsoid

The shape of the central body. - fixedReferencePoint
- Type: AGI.FoundationMotionCartesian

The motion of the reference point in the central body's fixed frame. - order
- 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.

A transformation from the ellipsoid fixed axes to east-north-up axes.
