AFCEA Course 102AJ
Military Satellite Communications
November 2, 3, 4, 5, 6, 1998
This course is Classified SECRET.

Fees:     Government Personnel     $990
          Industry               $1,395

Location:  AFCEA International Headquarters, Fairfax, Virginia

Satellite communications dominate current and planned military and
government communications systems.  This course provides an in-depth
understanding of current and future military satellite communications.
The military requirements and threat are developed.  The communication
aspects of the system (e.g. modulation, coding, and multiple-access) are
emphasized and the key problems of communicating in a jamming and/or
nuclear environment are presented.  All of the current and future
military and commercial satellite systems are described. The topics
provide a comprehensive perspective of satellite communications for
military applications.

The course is evenly balanced between general principles and discussions
of specific systems.  The course will include demonstrations of various
satellite communications equipment.


This course describes the fundamental aspects of satellite communication
systems engineering with emphasis on the description of current and
projected satellite networks for military usage.


The course is designed for military communications systems planners,
engineers, managers, operators, system analysts, and decision makers who
need a thorough understanding of military satellite communications
systems design.  A general background in communications is recommended.
