Course Objectives

Communications speed is one of the major challenges faced by thousands of companies operating in remote or tough places around the world. As such, many companies choose to implement in their process flow, satellite systems that allow them to have an agile and independent communications network. Satellite Communications Systems is the only guide that covers the entire technology, from ground links through signaling, access, spacecraft, orbits and positioning.

This workshop is designed to provide a comprehensive understanding on the use and development of satellite communications and VSAT networks. The course provides principles and technologies used in the design and performance of satellite communications system.

After successful completion of this workshop, participants will be able to

  • Explain the basics principles of Satellite Communication and the satellite communications architecture.
  • Describe the concepts of satellite communication links, transponders, frequency bands, link budgets and how they are affected by antennas.
  • Understand the modern satellite propagation, multiple access, modulation, coding schemes and orbital aspects.
  • Explore VSAT architecture, propagation aspects, link design and analysis.
  • Explain VoIP and Video applied to VSAT and VSAT-base IP communications technologies.






Target Audience

This course is specially designed for strategic or technical managers, consultants, communications professionals, system engineers, network professionals, broadcasters who wants to explore satellite communication network and evaluate VSAT and other satellite communications products and service.
