|Examination Online||Online 2-hour exam taken within a 4-hour window||70|
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:
· Assignment assessment (30%) is based on 9 hours of laboratory performance including preparations and writeup report in the context of group experiments on a satellite communications modem with 2 students in each of the group; each group of students will be scheduled in 3 time slots of 3 hours each, and each student submit his/her report within a week after completion of the experiments. Individual formal technical report on the experiments.
· Online 4 hours period allowed to do the 2-hour paper of written examination (70%).
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
Feedbacks provided on the performance and technical report.
- The aim of this module is to build onto the knowledge gained in EEEM031 "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.

This module provides contents with knowledge through lectures and tutorials, and professional practical skills through practices in the laboratory, coursework and Lab report. It will help students to get particularly good learning, learn subject knowledge and skill and improve their capacity, covering the following aspects of the Surrey Pillars:
- Sustainability: this module is directly relevant to the SDG4 quality education for remote and rural areas as satellite provide global coverage for the students who may not be reached easily by normal terrestrial information infrastructure; to the SDG 9 industry, innovation & infrastructure as satellite has been considered as important part of the future 5G and 6G networks to support industrial IoT (IIoT) and global information infrastructure (GII); to the SDG 10 reduce inequality within & among countries as satellite has already been used to serve regions or countries which cannot be served economically to bridge the digital gaps for broadband Internet services; to SDG 17 partnerships for the goals as satellite naturally provides support for global coverage and collaboration and has been used to achieved goal by the International Telecommunication Union (ITU).
- Global and culture capabilities: the nature of satellite is global that it need global collaboration and multicultural environment for working together. The module has laboratory sessions to allow student from different countries and culture to work together. This has also been promoted by the ITU in the UN.
- Resourcefulness and resilience: the module covers both technical aspect and current development of the sectors to allow students to be aware the potential development and opportunity. In addition, the module also provides information for students to be able to work in quite different sector as required.
- Digital capability: as an important part of communication infrastructure satellite can provide services to enable many individuals and organisations to be able to participate social and professional life in digital and connected world. The new generation of Mega LEO satellite constellations will be able to reach any people anywhere and any times.
- Employability: currently there are great demand for skilled engineers in the satellite industries including satellite operators, manufacture, services providers and terminal producers and relevant electronic companies.
