GPS artwork?

Cool...I think

Really like this.

Why do the lines look 'scruffy' though?

Nice idea

I have noticed some weird shapes on my cyclemeter app on my iPhone, usually when I'm beach riding lol

Great fun but he must plan it on a map first!

the accuracies of GPS or A-GPS for that matter.

Agreed - can be a pain with phone handsets, compared with dedicated GPS devices.

I suspect the chipsets are relatively up to it, but the GPS antennas probably just about up to it - with things like A-GPS, and other cell / tower locations used. I've noticed it on my N8, when using Sports Tracker.

I think it's just the general limitations, it does not pinpoint you perfectly but within 5 to 20 meters in the best case if I remember rightly. Buildings make that a lot harder as signals bounce around off them or even line of sight to one is lost (hence A-GPS has come about).

We need Galileo up and running to get down to 1meter levels, doubt it gets around the building problem though.

Thought EGNOS had been live for some time?

My previous, standalone sat navs (both Garmin, although have a TomTom, too) had WAAS / EGNOS support, and seemed to work OK - perhaps a bit improved, with it turned on.

I think there's 2 factors, here - automotive sat navs tend to snap you to the nearest road, where they can feasibly do so, and phone handsets don't get as good reception (possibly chipset limitations, possibly antenna?) as dedicated sat navs - but on the plus side, often have things like A-GPS and other network / data related location services to assist - either to speed up acquiring, or to help with temporarily poor / lost signals.

Plus many smartphones have accelerometers and digital compasses - the types of things used in higher end standalones to attempt some degree of dead reckoning.

I know with my N8, with limited / poor / lost GPS reception, GPS tracking apps then tend to be subject to other location methods, which can be entirely more coarse grained.

Well neat! I was getting 11mm horizontal accuracy last week. I have a survey I did on a football pitch albeit with a total station rather than GPS. I did it as a parting gift to someone moving to a new company. I would display it but this is a family website.

Took me ages it did!

One of the routes I cycled near me last year looked like the canary on the Norwich City FC badge
