Parameters
- position
- Type: AGI.Foundation.CoordinatesCartesian
The starting point of the directed line segment. - direction
- Type: AGI.Foundation.CoordinatesUnitCartesian
The ray of the directed line segment. - radius
- Type: SystemDouble
The radius of the circular equatorial orbit.
Return Value
Type:
CartesianThe closest point on a circular equatorial orbit. If at the pole and looking along the polar direction,
Undefined is returned, since all points on the orbit are equidistant.
Remarks Input and output vectors are assumed to be in the fixed frame of the central body.
