GNSS Reference Setups

Click GNSS Reference Setup to display the following columns:

Column	Description
Unique Id	The unique identifier of the setup.
Included	Clear the box to remove the setup from any validation or processing.
Status	- The GNSS Reference Setup has not been processed. - The GNSS Reference Setup has been successfully processed and the resultant coordinates has been used to update the vertex. - The GNSS Reference Setup has been modified and it is recommended that the observations are reprocessed. - The GNSS Reference Setup has been processed however errors were detected in the data. - A tolerance has been exceeded.
Point Name	The name of the reference station.
Setup Vertex	The unique identifier of the vertex that will be updated when the GNSS Reference Setup is processed.
Easting	Edit the reference stations easting coordinate.
Northing	Edit the reference stations northing coordinate.
Height	Edit the reference stations orthometric height.
Coordinate Class	The coordinate class assigned to the reference station point.
Antenna Height	The height of the reference antenna.
Reference Equipment	The Unique ID of the GNSS reference equipment.
Rover Equipment	The Unique ID of the GNSS rover equipment.
Data Format	The format of network RTK corrections.
Mount Point	The mount point name for your network RTK correction type.

Measurements

Click GNSS rover measurements to display the following columns:

Column	Description
Unique Id	The unique identifier of the observation.
Included	Clear the box to remove the observation from any validation or processing.
Status	- The GNSS observation has not been processed. - The GNSS observation has been successfully processed and the resultant coordinates has been used to update the vertex. - The GNSS observation has been modified and it is recommended that the observations are reprocessed. - The GNSS observation has been processed however errors were detected in the data. - A tolerance has been exceeded.
Point Name	The name of the observed point.
Target Vertex	The unique identifier of the vertex that will be updated when the GNSS observation is processed.
Coordinate Class	The class given to the measured point.
Antenna Height	The height of the rover antenna
Position Class	An indication of the quality of the GNSS position and the survey method used..
Horizontal CQ	The initial estimate (as computed by the GNSS receiver) of the precision of the GNSS horizontal position.
Vertical CQ	The initial estimate (as computed by the GNSS receiver) of the precision of the GNSS vertical position.
Start Time	The start time of the GNSS observation.
End Time	The end time of the GNSS observation.
Static	Checked if the GNSS measurement mode was 'Static'.
Network	Checked if the measurement mode was Network.
Epochs	The number of epochs for the GNSSS observation.
Satellites	The number of GNSSS satellites used to determine the GNSS position.
HDOP	Horizontal dilution of precision at the time of the GNSSS observation.
VDOP	Vertical dilution of precision at the time of the GNSSS observation.
PDOP	3D dilution of precision at the time of the GNSSS observation.
GDOP	Geometric dilution of precision at the time of the GNSSS observation.
GPS	Checked if GPS satellites were used to determine the position.
GLONASS	Checked if GLONASS satellites were used to determine the position.
Galileo	Checked if Galileo satellites were used to determine the position.
BeiDou	Checked if BeiDou satellites were used to determine the position.
QZSS	Checked if QZSS satellites were used to determine the position.
SBAS	Corrections broadcast from geostationary satellites were used to determine the position.
Measurement Purpose	Click the box to edit the purpose of the measurement.
Code	Do one of the following: Click the box, then type the new code. Click the box then click . In the Code dialog, select a code from the list. Select a layer lookup table in the Coding Processing Options to view or enter mapped field codes.
Horizontal Targeting Error	Used in adjustment this is an estimate of the accuracy in which a rover antenna can be held horizontally over the point. Click the box to edit the estimated error for the observation. Alternatively, type global values in the Processing Options.
Vertical Targeting Error	Used in adjustment this is an estimate of the accuracy in which a rover antenna can be held vertically over the point. Click the box to edit the estimated error for the observation. Alternatively, type global values in the Processing Options.
Variance Scale Factor	Click to edit the variance scale factor for the observation.
Tilt Compensated	Indicates if the tilt compensator was used to adjust the target height..

Notes

Select a GNSS measurement node in the left-hand pane to display the related data in the right-hand pane.
To control the columns that are displayed, right-click on the data grids column header, select Columns and click the column to display or hide.
Monitor the Status of the observation and reprocess when necessary.
While the Horizontal CQ and Vertical CQ boxes are not editable, the covariance estimate can be scaled using the Variance Scale Factor.
Select Unknown or New in the Measurement column for feature processing to apply edits to the measurement Code.
Only one status symbol is displayed per observation. Resolving a symbol may expose a or symbol.
Results must be processed (not simply validated) to resolve status symbols as a validation does not apply the changes.
