GNSS AWARENESS (1 day)
Setting Out For Construction is an Approved Training Organisation
- CITB Assured
- Eligible for Flexible Workforce Development fund, GRANT BACK fund, CITB Skills and Training fund and/or levy grants.
About This Course
This course is for anyone who would like to be able to set out or survey using GNSS and can be delivered on Leica, Trimble or Topcon equipment. This course was written, and is delivered by Site Engineers for Site Engineers.
This course assumes a working knowledge of 3D coordinate geometry and construction drawings.
Our CITB Assured GNSS Awareness course begins by looking at the basic principals of GNSS technology. You will learn how Satellites communicate with GNSS receivers, coordinate systems and conversion files, what errors can occur and how to minimise them. You will also learn about the varying GNSS surveying methods, as well as how to set up the hardware, such as VRS/base and rover.
By the end of the course, you will be able to understand how GNSS technology works and have a sound knowledge of how to set up the instruments correctly for varying surveying techniques.
On completion of the course, you will receive a CITB certificate and your achievement will be uploaded to the CITB Construction Training Register.
