Something BIG is happening in space — and satellite communications are changing fast.
LEO mega-constellations, Direct-to-Device (D2D) connectivity, 5G Non-Terrestrial Networks (NTN), software-defined satellites, and new satellite architectures are transforming how the world connects.
Satellite Communications Fundamentals is a beginner-friendly course designed to take you from the basic principles of communications to the technologies behind modern satellite networks.
You don't need previous satellite experience. We start with the fundamentals — wired and wireless communications, frequency bands, satellite orbits, and constellations — and progressively move into modern satellite engineering and Direct-to-Device communications.

From Fundamentals to Modern Satellite Networks
This course is designed as a progressive learning journey.
We begin with the concepts needed to understand any satellite communication system. From there, you'll explore GEO, MEO, and LEO constellations before moving into one of the most important developments in modern telecommunications: Direct-to-Device satellite connectivity.
You'll learn not only what these systems do, but also how they work — from the smartphone and radio link to the satellite payload, constellation, gateway, mobile core, and Internet.
By the end of the course, you'll have a complete picture of how a modern satellite communication network operates from end to end.
