CoVariance with SA
Observation Properties
The instrument properties dialog now includes a CoVariance button which offers direct access to the covariance matrix for the instrument base. This is updated based upon the last covariance analysis per- formed, either through USMN or the Uncertainty Context Manager.
The covariance for a single point observation can also be directly accessed from within the point’s properties.
The point covariance can be displayed in either of 3 forms:
-
WRT Instrument Base Frame. With Respect To (WRT) the in- strument’s base. This option represents the points uncertainty only.
-
WRT World Frame. With Respect To (WRT) the World Frame. This option includes both the point uncertainty and the instru- ment’s placement uncertainty with respect to the World frame.
-
WRT Working Frame. With Respect To (WRT) the Working Frame. This option includes both the point uncertainty and the instrument’s placement uncertainty with respect to the Work- ing frame.
