Course Aim

This one-day Satellite Communications—Overview course (which is also the first day of our Satellite Communications—Intermediate and Satellite Communications—Advanced courses) provides attendees with a comprehensive overview of the issues associated with the design and operation of satellite communications systems. Some basic familiarity with communications fundamentals is assumed so prior attendance at our Fundamental of Communications Systems course is recommended. Attendees receive a copy of the presenter’s book Principles of Satellite Communications.
