Re: What's the point of this?
"The only really hard reason to build your own GNSS system is if you want to conduct some overseas military operations using precision munitions and you don't want the USA stopping you from doing so. Given that the EU members seem hell bent on having pathetic military capabilities, apart from France perhaps, one wonders why the EU is bothering with Galileo at all apart from the bragging rights."
As I understand it, GNSS is critical for precision ICBM and SLBM targeting. Without it, you are limited to countervalue strategies (city busting with large or many warheads). Counterforce strategies require GNSS. Countervalue is useful for deterrence, but for actual war-fighting you really want precision to take out hardened military and political targets.
If Europe wants a real deterrent capability, you need your own GNSS.
China and India are primarily armed with shorter ranged missiles aimed at targets within several thousand kilometers. That's probably why they both started with regional nav systems...
