GNSS and Network RTK
[ Book online ]
This basic/intermediate course, offered in association with Ordnance Survey, introduces delegates to the theory and practice of using Network RTK GNSS for centimetre-level positioning. The programme includes a mixture of lectures, field and computer practicals, and group discussion.
The following topics are covered:
- Overview of GNSS
- Errors in GNSS and how to mitigate them
- Working in the urban canyon and other challenging environments
- Coordinate types and transformations, with particular reference to the British Isles
- Principles of Network RTK and best practice for its use
- Future developments in GNSS and its infrastructure
The course is principally aimed at new users of precise GNSS for surveying, and experienced practical GNSS users who desire an increased understanding of how it works and how modern developments in infrastructure have changed the way we use GNSS.
