Pos Vel Projected Covariance
Provides data about position/velocity covariance matrix relative to selected set of axes. The covariance is transformed into the requested reference frame using a 6x6 block diagonal transformation matrix consisting of two 3x3 coordinate transformation matrices along the diagonal. The result of this transformation is that the original covariance is simply expressed relative to the new axes and the effects of the rotation of the axes are ignored. The covariance information is reported in sigma-correlation form. Any set of axes defined in the Vector Geometry Tool is available for use, including user defined sets. The data requires position/velocity covariance to be defined for the object. Note: This data provider does not support interpolation of the position/velocity covariance matrices. Output is limited to the times of the stored ephemeris points.
Available for these objects: LaunchVehicle, Missile, Satellite
Type: Fixed data.
Availability: Reports
