ELEC6249 GPS and its Applications

Module Overview

This module will be first offered in the 2020/21 academic year. The intention of this module is to provide the students with a sound grasp and understanding of the fundamentals of GPS systems including the three main segments of a complete system: space, ground and user. Other topics covered will be the navigation equations, GPS performance and error effects, and GPS navigation applications such as land, sea and air vehicle navigation and tracking, aircraft automatic approach and landing using GPS, precision landing of aircraft using integrity beacons, spacecraft attitude control using GPS carrier phase, precise time and time interval measurement, surveying with the global positioning system, geodesy and orbit determination.

Aims and Objectives

Module Aims

To present the fundamental principles and engineering techniques used in the design and operation of GPS and to relate them to the current and future aerospace applications.

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • GPS systems and techniques in use at present so that students can gain a clear understanding of the principles involved, the methods of implementation and how the systems relate to the operation of GPS systems. Future requirements will be discussed to indicate the development required of current and future GPS systems.
  • How component parts, subsystems and systems are integrated into complete systems and the communications and interrelationships between the various system elements. Additionally, critical constraints on these systems, how the aerospace systems operates in relation to them and the requirement of future generation systems will also be addressed.
Transferable and Generic Skills

Having successfully completed this module you will be able to:

  • Study and learn independently.
  • Solve problems.
Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

  • Understand the key factors determining the design of GPS systems used in aerospace applications.
  • Apply the GPS mathematical models and set up and solve problems involving GPS observables.
  • Have an appreciation of the issues concerned with GPS performance and error effects.
  • Understand and identify the key components and signals of GPS systems and how they interact with one another.
  • Have an appreciation of the properties of a range of different feasible GPS architectures.
  • Describe different methods of detecting and dealing with the failure of components and (sub) systems.
