Satellite: Pos Vel Rotated Covariance: PositionCovPrincipal

Reports data about position covariance matrix including orientation of its principal axes relative to the PositionCovPrincipal axes and dimensions of the associated sigma scaled equal probability density ellipsoid. Any set of axes defined in the Vector Geometry Tool is available for use, including user defined sets. The data requires position covariance to be defined for the object.
