Quality Control Tab of the Properties
Window for a GPS Observation
You can open this tab after selecting the
Properties command from
the pop-up menu for the highlighted line in the GPS Obs
tab. The
Quality Control tab contains:
• pane with information
about highlighted GPS observations
(marked in red on the views) that did not pass some of the quality
control checks.
• I
gnore QC check box - if this parameter is checked, all quality
control tests are not performed for the given GPS observation.
This parameter is unchecked by default.
Covariance Matrix Tab of the
Properties Window for a GPS
Observation and GPS Occupation
Displays the six modified elements of the covariance matrix for the
given RTK GPS observation and GPS Occupation in current units:
• Sigma X
- the square root of the Cov [X,X] diagonal element.
• Sigma Y
- the square root of the Cov [Y,Y] diagonal element.
• Sigma Z
- the square root of the Cov [Z,Z] diagonal element.
• CorrXY
- dimensionless correlation factor X-Y. Corr[X,Y]
=Cov[X,Y]/(SigmaX*SigmaY).
• CorrXZ
- dimensionless correlation factor X-Z. Corr[X,Z]
=Cov[X,Z]/(SigmaX*SigmaZ).
• CorrYZ
- dimensionless correlation factor Y-Z. Corr[Y,Z]
=Cov[Y,Z]/(SigmaY*SigmaZ).
