|Assessment type||Unit of assessment||Weighting|
|Examination||EXAMINATION - 2HRS||70|
Not applicable: students failing a unit of assessment resit the assessment in its original format.
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 of satellite communications and networks, as well as the ability to analyse problems and apply measurements on the satellite testbeds.
The Assignment will assess the ability to use the satellite testbed for performance measurements, evaluations and report. The laboratory experiment will evaluate the acquired technical skills and expertise required for performance characterisation of satellite communication systems.
Thus, the summative assessment for this module consists of:
· 2 hours closed book written examination
· 6 hours of laboratory performance in the context of group experiments with a satellite communications modem with 2 students in each of the group.
· Individual formal technical report on these experiments.
· Each group of students will be scheduled in 2 time slots of 3 hours each, and each student submit his/her report with a week after completion of the experiments.
Formative assessment and feedback
For the module, students will receive formative assessment/feedback in the following ways.
· During tutorials/tutorial classes
· By means of unassessed tutorial problem sheets (with answers/model solutions)
· During supervised laboratory sessions
· Via the marking of written reports
· Via assessed coursework
- The aim of this module is to build onto the knowledge gained in "Satellite Communication fundamentals", and provides the student with a detailed understanding of the techniques used and applications in modern Satellite Communications and Networks. In addition, to provide the student with familiarity of simulation, analysis and measurement techniques used in the design and analysis of Satellite Communications links.

Methods of Teaching / Learning
The learning and teaching strategy is designed to achieve the following aims:
- Students taking this module will have a detailed knowledge of modern satellite communication techniques and systems as well as an appreciation of all the current application areas.
- In particular, the students will have obtained the skill of carrying out simulations / measurements of a satellite communication link using a commonly available and industry standard software package or measurement equipment.
Learning and teaching methods include the following:
- Lectures: Total 30 hours of lectures (3 hours per week)
- Labs: 2 x 3 hours sessions using a satellite system testbed.
- Assignment(s): Report based on using the satellite system testbed.
- Familiarisation with test equipment (spectrum analyser, BER test set etc)
- Measurement for spectrum of various modulations and coding rates
- Measurement of BER with changing C/N
- Assessment of impact of interference
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
