What is a GPS site calibration?
Calibration is the process of adjusting projected (grid) coordinates to fit the local control. A calibration calculates parameters for transforming WGS‑84 coordinates into local grid coordinates (NEE).
How do I calibrate my Trimble GPS?
To calibrate point coordinates
- Enter the grid coordinates of your control points.
- Place the calibration points around the perimeter of the site.
- Measure the points with GNSS.
- Perform an automatic or a manual calibration.

What is a Trimble CAL file?
Trimble CAL to Topcon GC3 data exchange A free Windows application which converts Trimble calibration (CAL) files containing local site or map projection data into a Topcon localization (GC3) file for use in Machine Control.
How do I set up survey control points?
- Identify and mark a number of key fixed points that will serve as control (reference) for all subsequent surveying.
- Establish the baseline, an accurately measured distance between 2 control points.
- Station the tripod over a control point.
- Mount the transit (theodolite) on the tripod.
- Release the upper set screw.
What is GNSS calibration?
The main function of the GNSS calibration network is to determine the referential ITRF coordinates. Figure 4 presents the traceability chart and the ITRF coordinates are determined by GNSS positioning units.

How accurate is RTK GNSS?
RTK GPS Accuracy: What accuracy is RTK? RTK is used for applications that require higher accuracies, such as centimetre-level positioning, up to 1 cm + 1 ppm accuracy.
What is a JXL file Trimble?
Jobxml is an xml based format which allows for export of traverse or GPS data directly from the data collector to other programs. A jxl file can be exported from more recent versions of Trimble Survey Controller or Trimble Access. Copy the file with the extension .
What is a Trimble CFG file?
The Configuration Toolbox software enables you to create and edit GPS receiver configuration files. cfg) that contains all the receiver settings required for a particular job or application. Application files can be stored on both the receiver and computer.
