This has been known for a while. Check the PTTI archives.

This particular part of the Galileo project have been a paper castle. They have
not considered the fall of prices for GPS recievers and if their license is
say 1 EUR that would all of a sudden be an expensive component. 1 EUR will be
multilied by alot of factors before it hits the customer. That includes the
manufactuer and retailers add-ons for "added value". We have already seen that
for EGNOS/WAAS for instance.

I think they must scrap the whole license thing and release it for free, since
otherwise the license will be a threshold. They just didn't adapt the buissness
model that was there and the only thing they did was fool themselfs. They
didn't loose anything, they never had it in the first place.

Cheers,
Magnus
