Having done a little research, the EU is going to provide their commercial service free of charge, to preempt the Chinese and Japanese are who are also going to do so. Which apparently has all the commercial companies which helped along the way on the basis they would have the rights to sell it in various industries throw their toys out of the cot...
Note that the Japanese have their own GPS augmentation system - having your own is not necessary if you leverage off those already there - and as I have posted earlier, LEO augmentation based on systems such as Iridium are already proving just as accurate and at a fraction of the cost.
The DG of the EU GNSS, by and by, states the accuracy will be 20cm (8”), presumably horizontally.
