Pos Vel Rotated 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 transformation matrix consisting of two 3x3 coordinate transformation matrices along the diagonal and the skew-symmetric 3x3 matrix representing the angular velocity between the axes in the lower left.

The result of this transformation is that the original covariance is re-expressed relative to the new axes including the effects of the rotation of the axes. The resultant covariance matrix represents the uncertainty of the position/velocity expressed in the new axes.

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
