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.

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.

Available for these objects: LaunchVehicle, Missile, Satellite

Type: Time-varying data.

Availability: Reports

Any Axes component owned by the object is available for use, including user defined ones. Use the Analysis Workbench listing or the Report Manager->Report Content Properties tool to determine the actual set of components that can be used for a specific object.
