Teaching Rationale And Relationship

The lecture series is designed to impart theoretical knowledge, understanding and skills which are supported and developed by focussed practical sessions. A structured reading list allows students to manage their learning patterns and provides the opportunity to increase their depth of learning. Team working and problem solving are practiced and assessed.

The one small group teaching activity provides the opportunity for students to explore, in a directed way, the use of internet based GNSS positioning services. Specifically, issues relating to common pitfalls in use are explored e.g. coordinate datums and reference frames.

Assessment Methods

Assessment Rationale And Relationship

The specialist knowledge and understanding acquired during this module are assessed by means of an unseen written examination, database processing, computation, data interpretation and student reflection. Specific coursework submissions will allow the student to demonstrate their ability to report on and synthesise practical work.
