  • Latest software used
  • Small class sizes

This course is for anyone who would like to be able to set out or take surveys using GNSS and can be delivered on Leica, Trimble or Topcon equipment.

This course assumes a working knowledge of 3D coordinate geometry and construction drawings.

Course Content

By the end of the course, delegates will be able to:

  • Use GNSS terminology
  • Explain the basic principles of GNSS technology
  • List situations where GNSS is appropriate and situations where it is not
  • Carry out a site calibration to create a local coordinate system
  • List the potential sources of error in GNNS
  • List the factors affecting accuracy
  • Check and monitor the level of accuracy achieved
  • Select the correct scale factor for the task
  • Enter data into the controller manually
  • Connect the controller with the GNSS rover
  • Navigate around the menus and programs
  • Navigate the stored information in list format and map view
  • View, edit, add and delete data
  • Enter the correct settings
  • Select the correct prism constant
  • Take a topographical survey and record the results systematically
  • Set out points of known co-ordinates using the onboard functionality
  • Set out points in relation to a baseline using the onboard functionality
  • Set out points at given chainages and offsets along a radius e.g. road centrelines using onboard functionality
  • Transfer large amounts of data from the controller to the computer and vice versa
  • Extract line data e.g the horizontal distance and level difference between two points
  • Measure irregular areas and volumes such as stockpiles
  • Import and work with DXF and DTMs
  • Create and export DXFs and DTMs
  • Import and export data to and from Excel
