Europe Steps Up Satellite Capabilities Amid Doubts Over Musk's Starlink https://www.youtube.com/watch?v=_5VxZqamfzM
Rather than replacing the terminals (around 40k), is it possible to modify Starlink's terminals to use Eutelsat's network for example?
There is no commonality between the air interface etc between Starlink and the other networks, so you couldn't reuse terminal hardware off the shelf.
You could possibly reverse engineer a terminal and write entirely new firmware for it, but it's full of semi-custom silicon and so this would be extremely expensive.
There are secure boot protections, so you couldn't mass deploy that firmware in the field anyway. Each would need expensive individual rework by skilled hands to be converted.
