AFCEA Course 102AJ

Military Satellite Communications

November 2, 3, 4, 5, 6, 1998

This course is Classified SECRET.

CEU=2.8



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.



OBJECTIVE



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.



WHO SHOULD ATTEND



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.
