209 – Satellite Development at OHB
Gast: Christian Pauly, Matthias Tausche, Andreas Wortmann, Ingo Engeln
Host: Markus Voelter Shownoter: Tim Jurik
In this episode we get a peek into how OHB System AG in Bremen develops satellites — mostly based on the Galileo navigation satellites. We speak with Christian Pauly about systems engineering, with Mathias Tausche about manufacturing and integration, with Andreas Wortmann about the software on the satellites, and with Ingo Engeln about the company as a whole.
As a background, you may want to listen to omega tau 26 about satellite buses. omega tau 204 on Planet Labs’ small satellites may be interesting as a contrast.

A lot of technical details I never expected to hear in such a depth. Developing software for satellites must be really challenging. I love it!!
The part of Mr. Engeln was not technical enough for me but also good to know.
I wonder how the computaional model deals with caches and pipelines. Does such a model also contain the characteristics of the CPU or do you only want to use strictly deterministic hardware in spaceflight?
I don’t know … I will ask Andreas when he comes back from vacation.
Really very interesting episode Markus. Again I learned a lot. Thanks
Excellent episode, Markus. Probably the second best one yet :-). I’m going to go back and find the one I found transcendent now.
Very good initiative!
