Course #23

Satellite Communication Systems

November 3 - 7, 2014 . Dresden, Germany

We recommend you to submit your preliminary or firm registration at least 4 weeks before course start to ensure a seat on the course.

TECHNOLOGY FOCUS
Satellite communication systems are playing a significant role in the exchange and delivery of many types of information, from voice communications to high definition television and Internet services . Satellites are particularly appealing whenever large coverage is desired, and when either collect or broadcasting applications are considered. 
High reliability and flexibility for setting up links make satellites unique for specific applications. There are also used to complement terrestrial networks. However, satellites communications are faced with links impairments, limited bandwidth and power, and should allow access from multiple users with limited amount of interference. From system designer to service provider, one should understand the specific constraints and opportunities of satellite communications.

COURSE CONTENT
This course presents the techniques that are used and points out the limitations and performance that can be expected from geostationary satellite systems. Emphasis is placed on the trade-offs that can be exercised within the constraints of technology and regulations. The course is as practical as possible, underlying those techniques that are, or soon will be in use, with emphasis on performance trade-offs. 
The course is designed to provide the attendees with the relevant knowledge on satellite link design and communications techniques, including those used for broadcasting and multimedia communications (DVB-S, DVB-S2). Networking aspects are introduced, focussing on physical and access layers and satellite network architectures. Specific issues in connection with the operation of multibeam satellites and on-board regeneration are dealt with. A detailed overview on satellite communication payload, repeater and antennas, and earth station technology is given. Satellite communications engineering requires a combination of know-how in many various fields such as propagation, RF systems, antennas, signal processing, communications techniques, etc.
Several practical exercises are to be solved during the course to allow the attendees to practice the acquired knowledge. It includes a project on the design of a European multibeam satellite communications system. The design considers performance and technology trade-off and aims at a cost efficient design of the earth segment.

WHO SHOULD ATTEND
Engineers, scientists and technical managers involved in the planning, design and operation of satellite communications systems; designers and technical salesmen concerned with the manufacturing of satellite communication systems equipment; technicians involved in the operation and maintenance of earth station or in the control of the satellite.
