They are doing some significantly impressive maneuvers!

You can do a free course on how to program them on edX. Its conducted by the university of Munich (Technische Universität München)
You need some math and programming skills.

Originally posted by twhiteheadwell, in the real world, they would't be 2 meters apart, more like 20 meters. Even in that case GPS would not be reliable since at best you get there is 1 meter or 2. So it would have to rely on good inertial nav system, some kind of gyro affair maybe.

If anything tethered flight is easier as it reduces the degrees of freedom. It does allow faster flight in combined space which is what they were demonstrating.
I would think that GPS would be useless at those speeds and even video cameras might struggle to keep up making visual position control difficult.

It is nevertheless useful in navigation over small distances. If you average out the readings you can actually get better than 1m relative accuracy (not absolute accuracy but that doesn't matter).
My concern was how long ...[text shortened]... ute twice as fast or loose some accuracy.
I did the course I mentioned earlier and got 99% 🙂[/b]

They just started a re-run on 5th May. If you don't care about marks or just want to browse, then you can simply sign up and watch just the videos. I wouldn't recommend that particular course unless you have a maths and programming background, but there is ...[text shortened]... t of what I learnt in the MIT course was not known at the time I was at University 20 years ago.
