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.
