GNSS Measure modes

• The Measure mode page allows to change the type of GNSS measurements.

• The software offers different measure mode, for example to measure hidden points with a GNSS receiver.

• To open the Measure mode page press on the corresponding icon on top of right side-panel.

  

• This open the Measure mode page.

  

  • Standard: standard measurement with GNSS pole vertical.

  • Tilted pole (IMU): enables the GNSS receiver IMU to measure points with the pole tilted. Available for GNSS receivers with IMU sensor.

  • Laser: measures points using the green laser distancemeter. Available for GNSS receivers with laser distancemeter (GS11 and iCG11).

  • Measure in images (quick): allows to take images using the GNSS receiver camera and calculates points directly on the images. Available for GNSS receivers with imaging capabilities (GS11 and iCG11).

  • Pole offset: calculates the position of an hidden point by a distance from a measurement with pole tilted in the distance direction. Available for GNSS receivers with IMU sensor.

  • Distance-Distance: calculates the position of a hidden point or multiple points by two distances to two reference points.

  • Alignment Offset: calculates the position of a hidden point by an alignment defined by two reference points.

  • Vertical offset: calculates the position of an hidden point by applying a vertical offset from the current measure.

  • Tilted pole (X-TILT): using the sensors in the controller, allows to measure hidden points with pole tilted. Available for GNSS receivers without IMU sensor.

  • E-Bubble (X-TILT): using the sensors in the controller, allows to show on the display an electronic bubble.

Laser measurement mode

• Allows to measure points using the GNSS receiver green laser distancementer. Different measure modes are available.

• When Laser mode is selected, the software allows to measure points using different methods:

  

  • Single point: measures single points with laser distancemeter.

  • Intersection by 4 points: calculates a new point as intersection by measuring with distancemeter 4 points on 2 different planes.

  • Horizontal scan: scans points horizontally at a fixed elevation using distancemeter.

  • Surface scan: measures points continuously on a surface.

• When measuring with laser distancemeter, Leica X-PAD activates the GNSS receiver camera to identify the point to measure not only with the green laser beam but also on the image.

• 

  Measure the points aiming with the green laser.

  • The GNSS receiver laser distancemeter emits a green laser beam that can be easily recognized on the surfaces.

  • The point to measure is represented on the GNSS receiver camera by a cross. If the cross is green, the point can be measured.

  • On the top-left of the screen the aiming area is zoomed to help to visualize the point to measure in case the green beam cannot be visualized on the surface. Press on the zoom screen to swap between standard view and zoomed view.

    

  • On the bottom-right of the screen it is visualized the laser beam status with point distance and estimated laser distancemeter error.

    • Measure possible: if the icon is green and the software displays distance and accuracy, the point can be measured with the laser.

      

    • Measure not possible: if the icon is yellow the point cannot be measured with the laser.
