One governed by a massively corrupt government, the other by a hodgepodge of
countries including several that can't even stay solvent. Why does that not
reassure me?

There's indeed a great chance Galileo will take over as the premiere
GNSS system.

However there's zero chance GPS will fail to meet minimal performance
standards in my view.

There's also zero chance of the market offering Galileo only GNSS
receivers (without at least GPS capability as well).

The real question is which GNSS system will offer the best
performance, which is mostly a ****ing match. In 10 years, all new
GNSS receivers will be at least double constellation, and most will be
triple (or more). The move by the Russian government of shoving
GLONASS down every Russian GNSS user's throat will add GLONASS to 90%
of new receivers by 2015, and Galileo will be adopted due to its
frequency commonality and the fact that L1C will be the premiere GNSS
signal in the future.

The end game is win win for users. Only the US govt prestige and the
GPS modernization schedule that is at stake.

Hopefully WAAS will be updated to include Galileo and GLONASS. That's
actually far more important than the GPS modernization schedule.

And we're still waiting for the Beidou ICD. Per usual, China is
stonewalling. The risk is Beidou will become irrelevant for users
outside of China.
