Satellite communications dominate current and planned military and government communications systems and make Net-Centric Warfare possible. This course provides an in-depth understanding of current and future military satellite communications. The military requirements and the associated technologies are addressed. 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. Internet protocol (IP) and IP over Satellite (IPoS) are addressed showing this protocol's strengths and weaknesses as a facilitator of Net-Centric warfare. All of the current and future military and commercial satellite systems are described including MILSATCOM's evolution. 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 in a net-centric and transitional communications environment.
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.
