Introduction to space engineering fundamentals, key concepts and missions

General outline

This session will provide our attendees with an overall summary of the various specific characteristics of the space environment and related constraints (module 1), along with the engineering concepts required to understand the technical fundamentals of a space mission (module 2). Based on these background elements, our attendees will go through each component that make up a satellite communications system (module 3) and a satellite Earth observation system (module 4).
