Edit Satellite Vector¶
Use this dialog to edit a satellite vector.
Where can I find the dialog?¶
Right-click in the observation list for satellite vectors and select Properties... from the context menu.
General Information about Satellite Vectors¶
The dialog displays the values for a satellite vector and its transformed observations. The transformation to the current coordinate system is performed during import. You can edit the vector components with their associated standard deviations and correlations afterwards. You can also edit the standard deviation of the transformed vector, To Point, and Ant. h to.
Transformation of Standard Deviations¶
A transformation is also performed when you click OK in the dialog, with one exception: If Std. changed is checked, the standard deviations are not transformed again. Std. changed is automatically checked if you manually change the transformed standard deviations in the dialog or select Calculate standard deviation from instrument in the context menu of the observation list.
Transform observation with standard deviation to map projection in the context menu also transforms again from geocentric X, Y, and Z from the measurements to standard deviation in the map plane. With this option, you can transform several vectors in one operation. Changed standard deviations are also transformed again with this function.
From Point¶
Starting point for the vector (base point). If the starting point needs to be changed, this must be done in the station dialog.
To Point¶
Endpoint for the vector. Use the command button on the right to give the endpoint a new name.
Ant. h to¶
Antenna height at the endpoint for the vector.
Note
If the antenna height at the starting point for the vector needs to be changed, this must be done in the station dialog.
Omit¶
By checking Omit, the vector will be excluded from the calculation. On the map, this is shown by the color of the satellite vector's arrow changing from gray to green, while in the list it is shown with the symbol "--".
Vector Components¶
dX, dY, dZ: The vector's X, Y, and Z components (Note: Not coincident with the X, Y, and Z directions in your local coordinate system).
StdX, StdY, StdZ: Standard deviation for the vector's X, Y, and Z components.
Qxx, Qxy, Qxz, Qyy, Qyz, Qzz: Correlations for the vector.
After Transformation¶
Dir. angle: The observation's direction angle. Map projection correction is not applied. This is applied first during adjustment.
Zenith dist.: The observation's zenith distance. Corrections for earth curvature and plumb deviation are not applied. These are applied first during adjustment.
Hor. distance: The observation's horizontal distance. Map projection correction is not applied. This is applied first during adjustment.
Std. dir., Std. zenith dist., Std. dist.: Transformed standard deviation for direction angle, zenith distance, and horizontal distance.
Qrr, Qrz, Qra, Qzz, Qza, Qaa: Correlations for direction angle, zenith distance, and horizontal distance.
