ELEC3225 Space Systems Engineering

Module Overview

This module will be first offered in the 2019/20 academic year. This module is intended for anyone interested in pursuing in more detail the space part of aerospace engineering. It looks at each of the key subsystems of a spacecraft in detail. It also introduces the overall theme of space systems engineering by emphasising the interfaces between subsystems and the iterative nature of spacecraft design and spacecraft systems engineering.

Aims and Objectives

Module Aims

To develop an understanding of spacecraft system engineering and the role of subsystem design.

Learning Outcomes

Knowledge and Understanding

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

  • An understanding of what space systems engineering is and what the main types of spacecraft are in terms of their functionality.
  • An understanding of the environment that a spacecraft has to operate in and some basic knowledge of how this environment can affect the spacecraft in terms of operation and reliability.
  • An understanding of the basics of orbital mechanics.
  • A basic understanding of the most important spacecraft subsystems and how these interact with each other.
