Occupy Check Setup
The Occupy Check Setup screen is similar to the Occupy Control Setup screen.
[Start Check Point Occupy]: Opens the Occupy Check Point screen.
Solve Calibration - Results
The Solve Calibration Results screen is used to display the results of the GNSS Resection / Backsight, as well as make
any changes to the horizontal and/or vertical control point assignments. You can also use this screen to access the
Calibration Settings screen to input the calibration parameters manually.
Before the Solve Calibration screen opens, the calibration is computed using all the assigned control points, and then
the automatic blunder detection routine runs to detect obvious blunders in the solution. If blunders are detected, then
you are prompted if you want to automatically remove the assigned points from the solution and resolve. If you tap
[Yes], the dimensions (H and/or V) of the points detected as blunders will be unassigned and the calibration will be
resolved. If you tap [No], then the results will open with all points still assigned with their original dimension in the
solution.
GNSS Resection / Backsight: Displays the current status of the solution:
Green Light: If the calibration is solved and no blunders were detected, you will see a green light and the status line
will show the root mean squared (RMS) error of the horizontal and vertical solution.
Yellow Warning Triangle: If the calibration is solved and no blunders were detected, but some of the points used have
a large residual error, you will see a yellow triangle and the status line will show the point with the largest horizontal
and/or vertical residual.
Red Stop Sign: If the calibration is solved, and blunders were detected that could not be clearly identified, or if you
were prompted to remove blunders and you said no, then you will see a red stop sign and the status line will indicate
there are possible blunders in the solution.
Yellow Arrow: If the calibration is solved, but the control points are not spaced far enough apart to run the automatic
blunder detection, then you will see a yellow arrow, and the status line will indicate the poor geometry of the control
points, or if the calibration fails to solve, you will see a yellow arrow and the status the status line will indicate the
failure to solve the calibration.'
The list of GNSS control points is shown in the box, along with the horizontal and/or vertical assignment of each
point. You can tap on the H and/or V column for each point to change the dimension assigned to use in the solution.
You can double tap on any point to see details about that point. When the calibration is solved, you will see horizontal
and vertical residuals (errors) in the columns for each point used for that dimension.
[Add Point...]: Tap to open the
Occupy Check Setup screen where you can select additional points to add as control
for the calibration solution.
[Details ...]: Tap to open the
Projection Details screen and shows the exact numeric parameters of the pending
calibration solution.
[Resolve]: Tap to recalculate the solution. This button appears if you change the horizontal or vertical control point
assignments
[Finish]: Tap to apply the calibration solution and open the
Data Collection screen.
Note: The calibration blunder detection routine will attempt to determine if there are any blunders in the GNSS control
points used. This detection is done independently of the residuals of the least squares solution. The blunder detection
routine is limited to a maximum of 15 GNSS control points. If you have more than 15 GNSS control points, the
