The resolution of the free service will be better both horizontally and vertically - i think ive seen 1m quoted - it wont be "precise" unless you pay for the add-ons - in the same way GPS can be made to be very precise if you buy the add ons - GPS has been giving near-precise values in survey circumstances for at least 20yrs
Anyone else really love their Garmin?

The Americans don't have to - in the end it was fudged with the USA that they used the same frequency - the yanks can just shut it down if they want to

I'm not sure Galileo will be much in the way of a revolution for cyclists. We'll all have to rush out and buy the latest must-have gadget, but we do that anyway. For cycling, GPS provides more than adequate precision. Except for occasional loss of signal ... and elevation.
Cycling isn't geocaching so as long as it tells you where you are to enable navigation, and how far/fast you've gone then further precision is a bit spurious.
Elevation is another story though. Numbers-obsessed cyclists (
not me guv, honest) want to know how much climbing they've done. And there are all kinds of problems there.

Theoretically, they can now in effect transmit their own signal over the Galileo one, thus rendering it unusable while not affecting GPS.
Unfortunately, the resources don't exist to be able to do so for up to 30 fast moving targets in low Earth orbit - if it were that easy numerous countries would have done that to GPS long ago. It's simply far easier, not to mention cheaper, to fly an F15 with an ASAT and shoot them down. The Chinese have the same ability as well. That's not to mention the particle beam weapons that the US and British will have deployed within the next 4 years.
Trust me, if it ever kicks off big time and the US or China suspect an aggressor in using Galileo for military purposes, the entire constellation will simply cease to exist rather quickly. Not that the system now seems likely to ever be fully mission capable, and has little prospect of on going maintenance launches of new birds as the system ages. Great idea, but flawed, under funded, and liable to be destroyed or rendered permanently inoperable in the event of even a limited war.

Thanks for the heads up.
So ... we shouldn't rely on Galileo for serious critical things like Strava uploads because minor trivial things like global conflagration could potentially put KOMs in jeopardy.
We need more of this kind of risk assessment.

Hmmm. I switched off GLONASS on my 520 to help maximise battery life. If there's a danger than satellites might get obliterated mid-ride I may have to revise that strategy. Something else to test.Thanks for the heads up.

Considering the US' propensity to start fights with other countries, there's quite likely to be a conflict of some sort before terribly long. It's a vulnerable infrastructure. You can josh all you want, but if you'd spent £500 in order to use Galileo you'd be pretty pithed off if it stopped working permanently. You'd either have a dead device, or one that you had to run on GPS instead, which you could have done for half the price in the first place.
So it is a genuine consideration if you're likely to be spending big wedge.

In the marine world the decca system was considered the bees knees until gps came along.
within a few years the system was switched off leaving you with a very expensive digital clock.

Coming in late to this, can't be arsed to read six pages of argument, but I saw a garmin edge touring on gumtree last summer for £110. Brand new/unopened, it dropped by £10 every two days or so until it hit £50. Too much of a bargain to ignore and even as I bought it I thought to myself "This must be a fake, broken, stolen" but got it home, plugged it in and never looked back. Honestly think it's the best £50 I've spent bike - wise.
Well my daughter preferred the 200 than the 25 so I had to pay her for the 25.
It's a great little unit for quick blasts out into the country and was very easy to use. My problem is that if it powers down when you start it back up it doesn't continue the ride (as stated on here) so it's gone as cafe stops are important. Going to give the 510 a go for a while and see how that goes.

Spent a lot on a 520, now wondering why I didn't get a £40 wireless computer instead.
