Expected prior/parallel learning: BEng-level understanding of digital telecommunications systems. MEng students might have partly acquired this through study of EEE3006 – Digital Communications (6-dcm).
Module purpose: Satellite communications are an important component of modern telecommunication systems. This course provides the student with an overall understanding of satellite communication systems, technologies and techniques and equips him/her with the design tools to enter employment in the sector.
This module aims to provide the student with a broad background across the whole of satellite communications including technology, markets and technical and business planning with detailed skills in the design and planning processes.

Satellite system futures
A state-of-the art update on current innovations and new systems proposals, standards issues and technology developments that shape satellite communications for the next 10 years.
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
provide the students with knowledge of design of satellite communications and then to allow them to practice the application of this knowledge on a real system design
provide the student with a wide knowledge of the state of the art in the subject and allow them to apply this to current engineering problems and to the design of future systems.
Learning and teaching methods include the following:
A series of lectures on satellite communications including a structured series of design exercises which the students complete as they progress through the course.(8x3hrs)
A system design assignment involving the planning and design of a real satellite communications system and business evaluation which tests the understanding of the above.(30hrs)
A series of 4 industrial seminars which gives the students a feeling for the state of the art and of the practical problems and issues facing industry in this area.(4x 1.5hrs )
The assessment strategy
The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The written examination will assess the knowledge and assimilation of terminology, concepts and theory in satellite communications system design and business processes, as well as the ability to analyse problems and apply mathematical models to solve and predict problems. The assignment is designed to test the real life solution of design of a satellite system given both technical and business parameters. It represents what the satellite engineer will face in industry.
Thus, the summative assessment for this module consists of:
• 2 hour closed book written examination
• Satellite systems design exercise with a 20-30 page report including results of calculations. The assignment is given in week 4 and handed in in week 11 of the course. Students are encouraged to discuss with visiting industrialists current issues pertaining to the assignment.
Formative assessment and feedback
For the module ,students will receive formative assessment /feedback in the following ways;
· During lectures by question and answer sessions.
· During lectures/classes by working through the design exercises throughout the course.
· During Seminars by questions and answers with industrial lecturers.
· Via feedback on the assignment
