Missile: Position Covariance CrossSection Impact

Position Covariance CrossSection Impact computes cross-section of the position covariance ellipsoid in a plane perpendicular to the object's CBF velocity at the stop time (impact time). The resulting ellipse is projected futher along the CBF velocity which makes up an elliptical cylinder. The cylinder's intersection with the local horizontal plane makes the final ellipse which is reported by this data provider.
