Module

CEG2719 : GNSS for Geoscientists and Engineers

  • Offered for Year: 2020/21
  • Module Leader(s): Dr Ciprian Spatar
  • Owning School: Engineering
  • Teaching Location: Newcastle City Campus
Semesters
Semester 2 Credit Value: 10
ECTS Credits: 5.0

Aims

The aim of the module is for students to understand the principles underlying the use of Global Navigation Satellite Systems (GNSSs) 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.

Overview of map projections;
Overview of geodetic datums and coordinate transformations.

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

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.

Alternative will be offered to students who are unable to be present in person.

Students should consult their individual timetable for up-to-date delivery information.

Assessment Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

he majority of factual and conceptual material relating to the learning outcomes is assessed within the unseen exam via the VLE. Analytical and computational aspects are assessed as part of the practical reports (coursework). Knowledge outcomes 3 and 4, and the skill outcomes, are particularly addressed in the assessed project report (coursework).
Practical 1 (coordinate types) write-up: 3% for satisfactory completion;
Practical 2 (GNSS in the field) write-up: 6% for satisfactory completion of fieldwork and seminar;
Practical 3 (coordinate transformations) write-up: 6% for satisfactory completion plus correct calculations;
Project (applications of GNSS): 25% for approximately 6 pages.
