AxesEastNorthUp.ComputeFixedToEastNorthUpRotation Method (Ellipsoid, Motion<Cartesian>, 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.

Namespace:  AGI.Foundation.Geometry
Assembly:  AGI.Foundation.Models (in AGI.Foundation.Models.dll) Version: 25.1.421.0 (25.1.421.0)
Syntax
public static Motion<UnitQuaternion, Cartesian> ComputeFixedToEastNorthUpRotation(
	Ellipsoid shape,
	Motion<Cartesian> fixedReferencePoint,
	int order
)

Parameters

shape
Type: AGI.Foundation.Geometry.Shapes.Ellipsoid
The shape of the central body.
fixedReferencePoint
Type: AGI.Foundation.Motion<Cartesian>
The motion of the reference point in the central body's fixed frame.
order
Type: System.Int32
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: Motion<UnitQuaternion, Cartesian>
A transformation from the ellipsoid fixed axes to east-north-up axes.
