What you will learn

On successful completion of this module a student should be able to:


- Relate control theory principles to the application of guided weapon systems. Distinguish between the types of guidance techniques employed on modern guided weapons and assess the appropriateness of the application.
- Assess the importance of the power supplies within a guided weapon and critically evaluate the performance of guided weapon guidance and autopilot systems in relation to the guided weapon power resources.
- Design roll, altitude and lateral autopilot systems using closed loop control methods and critically analyse the key components of missile autopilots and types of autopilot required by various guidance systems.
- Design command, homing and navigation guidance systems using closed loop control methods. 
- Critically evaluate the interaction between guidance, control and other key GW sub-systems
