CEG1705 : An Introduction to GNSS and its Applications
- Offered for Year: 2018/19
- Module Leader(s): Professor Peter Clarke
- Owning School: Engineering
- Teaching Location: Newcastle City Campus
Semester 2 Credit Value:
For students to understand the principles underlying the use of GPS at metre and sub-metre accuracy for applications in surveying, GIS, transport, agriculture, asset management, and scientific studies.
This module introduces students to the basics of positioning using Global Navigation Satellite Systems (GNSS), of which the US Global Positioning System (NAVSTAR GPS) is the prime example. We will cover the system components and the way they interact, the causes of measurement error and how they may be mitigated (including differential GNSS), and the relationships between the different coordinate types that may be used to describe position. The applications of metre-accuracy GNSS positioning will be discussed during lectures and within a self-directed project. More advanced topics include a brief introduction to precise (millimetre-accuracy) positioning using the carrier phase and the relationships between different historical coordinate datums used in the UK and worldwide (including height systems involving the geoid). Practical exercises include spreadsheet-based coordinate calculations, and the opportunity to test different types of GNSS receivers in the field.
Outline Of Syllabus
Overview of GPS –how code GPS works – errors affecting GPS, and their mitigation – differential GPS - overview of precise (phase) GPS – the future of GPS and similar systems.
Coordinate systems used with GPS – overview of map projections – datums and coordinate transformations.

Jointly Taught With
|CEG2719||GNSS for Geoscientists and Engineers|
Teaching Rationale And Relationship
Factual and conceptual material relating to all learning outcomes is covered in formal lectures; more interpretative and application-based material is encountered in the individual project. Knowledge outcomes 1 and 4, and the skills outcomes, are further covered in computer-based practicals on computational aspects of coordinate systems and a practical field exercise involving the collection of actual GPS data, followed by analysis and interpretation of errors.
The format of resits will be determined by the Board of Examiners
|Written Examination||120||2||A||70||Unseen written exam|
|CEG2719||GNSS for Geoscientists and Engineers||2||N/A|
|Practical/lab report||2||M||15||Practical/fieldwork satisfactory completion of report - 100 words.|
|Report||2||M||15||Project report of approx 4 pages.|
Assessment Rationale And Relationship
Practicals/fieldword 15% for satisfactory completion and final report x 100 words.
Project (applications of GNSS): 15%
The vast majority of factual and conceptual material, relating to all learning outcomes, is assessed within the unseen written exam.
Analytical and computational aspects are assessed as part of the practical reports (coursework). Knowledge outcomes 3 and 4, and the skills outcomes, are particularly addressed in the assessed project report (coursework).
