I found this whilst looking for Galileo proposed accuracy, below.

Is it just my nasty suspicious mind, but are we being told -
No matter whether Galileo satellites have greater accuracy or not,
they will be 'competitive' - ie no better than - existing gps?
Are we still going to be stuck with +/- 15-20 m accuracy?


The GNSS state-of-the-art is just under a meter using two
frequency signals without augmentation. That will be true
for all three impementations: Galileo, GPS and Glonass.



Sam, please clarify your "meter" value. I believe you are referring
to the output navigation signal error and not end user position
accuracy.

The article in InsideGNSS (see: http://www.insidegnss.com)
indicates sub meter horizontal position accuracy without
any augmentation. These figures were bases of expected
dual frequency Galileo and GPS signals that are currently
not available to us...

However, professional equipment currently realizes these
kinds of accuracies, and much better, using just the GPS L1
C/A signal with differential corrections.
