How do you test ground-breaking satellite software under real flight conditions? Why not build a satellite? A new design developed by ESA promises new opportunities for European space industry to test software on an actual mission in space.
The popular image of a 21st-century satellite includes a sleek design, gossamer solar arrays, ultra-high-tech components and cutting-edge digital electronics. And the onboard software must be the very latest thing, too, right?
Wrong. Or, at least, the reality is much more prosaic: software used in satellites today is certainly good, but it rarely runs the latest operating systems, languages or interfaces.
