An Overview of Satellite Communications

Satellite in orbit transmitting signals to points on earth

This course provides an overview of the principles and applications of satellite communications. It is designed especially for professionals who are new to this field or who require basic knowledge and concepts to deal with technical or management aspects related to satellite communications.

In this 2-day course, you will be introduced to the different types of satellites and the purposes they serve, such as the Low Earth Orbit (LEO), Medium Earth Orbit (MEO) and Geostationary Earth Orbit (GEO) satellites. You will learn about propagation delays and free space loss, multiple access techniques that include time division multiplexing and frequency division multiplexing, and link power budget.

In addition to theory, this course will also present real-world examples to give you a practical understanding of how satellite communications work. More specifically, examples of typical VSAT applications like PDH, SDH, Ethernet, DBV, etc. will be covered.

  • 3G/4G/5G mobile network operators
  • Broadcasting companies that utilize satellite links
  • Telecommunications companies (PTTs, carriers)
  • Satellite operators
  • Internet service providers
  • IT & system integration companies
  • Multinational companies that rely on satellites
  • Professionals in non-technical domains (eg. management, finance, PMO) who wish to learn about satellite communications
