Satellite data networks have become an important tool of corporations, government agencies as well as consumers needing remote access to the Internet. In this intermediate level, one-day course the instructor reviews the design and use of such networks, which employ inexpensive very small aperture terminals (VSATs). The instructor will provide up-to-date information and methodologies to employ communications satellites specifically for data communications and the Internet. The focus is unique because it combines theory and practice, addressing currently available technology solutions as well as the foundations needed to understand them.
Who Should Attend
Communications engineers and networking specialists who wish to understand how communications satellites are employed to provide data communications services, particularly with TCP/IP-based very small aperture terminals (VSATs). A background in satellite communications or radio frequency systems is desirable but not essential. This course will apply to any commercial or government organization that currently employs satellite communications for data applications, or to those considering how to do so.
- Understand how communications satellites are applied to two-way data communications
- Be able to conﬁgure a satellite data network to provide Internet-based services

- Architecture of the space segment - GEO and non-GEO orbits, impact on performance and coverage
- Satellite construction: program requirements and duration; major suppliers: Boeing, EADS Astrium, Lockheed Martin, Northrop Grumman, Orbital Sciences, Space Systems/Loral, Thales Alenia
- Basic design of the communications satellite - repeater, antennas, spacecraft bus, processor; requirements for launch, lifetime, and retirement from service
- Network arrangements for one-way (broadcast) and two-way (star and mesh); relationship to requirements in government and military
