This Is Real Art has made a series of charming informational films on the way that satellites work
The films were made for Astra, the European satellite operator not the reasonably priced car, and will be used both internally and to educate potential clients about what the company does.
There are seven films in total, covering everything (and indeed slightly more than) you might want to know about the operation of a satellite. Including sections on history, physics, control, launch, why we need satellites, business and the future.
We have two, including Why Do We Need Satellites?
And, yes, that is Johnny Ball doing the voiceover.
