1-day GNSS Awareness
Learn how GNSS Technology works, how to choose correct coordinate systems, how to mitigate GNSS related errors and how to set up, set out and survey using GNSS receivers.
Description
GNSS technology seems straight forward and easy to use on the surface but this GNSS course will not tech you how to push buttons but rather, it will teach you the fundamentals of GNSS technology and how to use it correctly for a variety of situations.
You will begin by learning how satellites communicate with our GNSS rovers and base stations, what errors can occur, how to reduce errors, how coordinate systems work and how to select the correct one for the job. You will then carry out practical exercises and use GNSS rovers and base stations to carry out surveying and setting out tasks such as setting out control points, carrying out a site calibration and general surveying/setting out tasks.
This course was created by Site Engineers, for Site Engineers and by the end of the course, you will feel confident about using GNSS technology on your site and you will be armed with the knowledge you need to do the job correctly.
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
Prerequisites
- Have a basic understanding of setting out/surveying concepts
