GPS and its Applications

Learning Outcomes

Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

• Have an appreciation of the properties of a range of different feasible GPS architectures.
• Understand the key factors determining the design of GPS systems used in aerospace applications.
• Describe different methods of detecting and dealing with the failure of components and (sub) systems.
• 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.
• Apply the GPS mathematical models and set up and solve problems involving GPS observables.

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:

• Solve problems.
• Study and learn independently.

Assessment strategy

In-class quiz will be provided to students as a formative feedback.

Formative

This is how we’ll give you feedback as you are learning. It is not a formal test or exam.

Summative

This is how we’ll formally assess what you have learned in this module.

Referral

This is how we’ll assess you if you don’t meet the criteria to pass this module.

Repeat

An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
