Course Name
Satellite Communications Fundamentals
Course Number
LS 123 107
Course Duration
2 days
Course Description
The general 2-day course provides an introduction to
communications satellite technologies, services, orbital
mechanics to satellite design and launch, configuration and
installation of earth stations, the implementation of
communications links, the set-up of the satellite network, the
capabilities, and limitations of current satellites.
The popular and intensive course provides the attendees with
an in-depth background of satellite communication techniques
as well as a state of the art update on key emerging technologies
and future systems.
It addresses all important aspects of the subject, including
traffic, multiple-access techniques, link budgets, the spacecraft
bus, and the orbits.
