GVF500 Ed2: Introduction to Satellite Communications

Course details

  • Comprehensive overview of the technology and business of satellite communications.


Covers history, launchers, orbits, frequencies, networks, equipment, bandwidth, applications, markets, regulations, and industry structure, and much more. Upon completion, trainees will be equipped with a solid understanding of how the satcom market is structured and the capabilities of the technology that makes it all possible. Edition 2.1 (Aug 2019) includes high-throughput satellites, new launcher players, new market data, and other updates.


Everyone who would benefit from a broad knowledge of industry fundamentals, including sales executives, marketing managers, business leaders, and technical, engineering, operations, quality, and customer service staff.


A quiz after each lesson reinforces student knowledge. A GVF certificate of completion is generated when the student has visited all pages and passed all quizzes.


General familiarity with computer and voice communications


Animated & interactive HTML/Flash, self-paced, on-line format requiring internet access while studying the course material. High speed access is preferred but is NOT required. Current versions of browser and Adobe Flash player must be installed on student’s computer.
