- This course describes orbital mechanism of satellites.
- The multiplexing and multiple access techniques of Satellite communication are also discussed.
- GPS and other applications of satellite communication are covered in this course.
On completion of this course, the students will be able to
- Discuss various multiplexing and multiple access techniques.
- Design satellite uplink and downlink under various conditions.
- Demonstrate the GPS concepts for ethical usage in society.
The courses cover the most relevant aspects of satellite communications, with emphasis on recent applications and developments. The course begins with a review on the history and basic concepts of satellite communications. Next it covers the orbital aspects, with emphasis on the geostationary orbit followed by a discussion of satellite subsystem and launching methods. The design of a digital satellite link is discussed in detail, including link budget, modulation, error control and multiple access methods. Frequency assignments and propagation aspects that affect the satellite link are then discussed. Antennas and earth station technology are presented, inclu ding the design of very small aperture terminals (VSATs). The course then covers non-geosynchronous orbits and their applications. Specific applications of satellites are also explored, including the global positioning system (GPS), satellites for mobile communication, and satellites for Internet.
