Position determination with satel-
lites appearing in all four quadrants.
Description
The Coordinate Quality is an indicator for the estimated quality of the point
coordinates. The coordinate quality of the measurements is used in point aver-
aging.
Type Description
Est 3D CQ Estimated 3D coordinate quality of computed position.
Est 2D CQ Estimated plan coordinate quality of computed position.
Est 1D CQ Estimated height coordinate quality of computed position.
Vertical angles are always assuming zenith angles and not elevation angles.
Standard deviations of circle readings relate to one face measurements.
