This course introduces you to the theory and practice of using Network RTK GNSS for centimetre-level positioning. Developed in association with Ordnance Survey.

The programme includes a mixture of lectures, field and computer practicals, and group discussion.

We'll cover the following topics:

• 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
