Projection Calculator – Rotation
Convergence: Displays the computed rotation from grid north to geodetic north.
Rotation: Displays the computed rotation from geodetic north to grid north.
[< Back]: Returns you to the first Projection Calculator screen.
[Accept]: Copies the two computed values to past results and returns you to the first Projection Calculator screen.
Projection Calculator – Scale – Height Correction
Ellipsoid Height: Enter the WGS84 ellipsoid height for your current location. This value will be used to calculate the
height above the terrain component of the scale factor. This is sometimes referred to as the sea level correction.
[< Back]: Returns you to the first Projection Calculator screen.
[Solve >]: Takes you to the final screen.
Projection Calculator – Scale
Mapping Plane Scale Factor: Displays the computed mapping plane scale factor on the selected mapping plane at the
reference point.
Ellipsoid Scale Factor: Displays the computed ellipsoid scale factor at the reference point.
Combined Scale Factor: Displays the Mapping Plane Scale Factor multiplied by the Ellipsoid Scale Factor. This is
the ground to grid scale factor.
Inverse Combined Factor: Displays the inverse of the Combined Scale Factor. This is the grid to ground scale factor
and is the value used in the calibration solution.
[< Back]: Returns you to the previous Projection Calculator screen.
[Accept]: Copies the two computed values to past results and returns you to the Main Menu.
File Management
[Survey] [File Management]
The File Management routine is used to manage post processing files on a supported GNSS receiver. The routine can
delete post processing files from the receiver or recover files that were recently deleted. Post processing files can also
be copied or moved from the receiver to the data collector for more convenient transfers to a PC.
Active Files tab: The Active Files tab lists the details of all the files that are currently on the connection target:
If connected to the receiver, the files on the receiver's internal memory are listed.
If connected to the SD card, it shows all SP1 files in the SD card slots.
