Advanced Satellite Communications Systems Training
Advanced Satellite Communications Systems Training Course Description
This three-day Advanced Satellite Communications Systems Training covers all the technology of advanced satellite communications, as well as the principles behind current state-of-the-art satellite communications equipment. New and promising technologies will be covered to develop an understanding of the major approaches, including network topologies, VSAT and IP networking over satellite. Material will be complemented with a continuously evolving example of the application of systems engineering practice to a specific satellite communications system. The example will address issues from the highest system architecture down to component details, budgets, writing specifications, etc.
• Characteristics of satellites – GEO vs. non-GEO, area coverage vs. spot beam, bent pipe vs. processor-based
• Characteristics of satellite networks – broadcast, interactive, star and mesh, high-throughput satellite (HTS) alternatives
• The tradeoffs between major alternatives in SATCOM system design.
• SATCOM modulation and coding tradeoffs and link budget analysis.
• DAMA/BoD for FDMA, TDMA, and CDMA systems.
• Critical RF parameters in terminal equipment and their effects on performance.
• Technical details of RF antennas, amplifiers and receivers.
• Tradeoffs among different FEC coding choices.
• Use of spread spectrum for Comm-on-the-Move and aeronautical broadband.
• Characteristics of IP traffic over satellite.
• Innovative approaches using phased arrays, cancellation and adaptive coding and modulation
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
