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.

Customize It:

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.
