This default CovarianceMatrix for sets of initial values in the ImageOrientation data structure specifies a diagonal matrix with the same value for the position coordinates, and a different value for the attitude values. The position coordinate variances correspond to a standard deviation of about 5337 metres, and the attitude variances correspond to a standard deviation of about 1.089 radians. 6 SensorPositionAny1 SensorPositionAny2 SensorPositionAny3 SensorAttitudeAny1 SensorAttitudeAny2 SensorAttitudeAny3 m m m r r r 28490000 28490000 28490000 1.186 1.186 1.186
