Is the gps tracking more accurate with 3G on?

[jabingla2810]

Ok this may be a really stupid question.

But Ive just started using an app to track my bike rides. I just start the app, throw my phone in my bag and forget about it till I get home.

I've been turning off 3g as the gps alone is a battery hog, however does the 3g signal aid the gps using triangulation or something?

Any info is much appreciated 🙂

What do you mean by "turn off?"

Are you just using EDGE instead of 3G? Or are you putting on airplane mode and killing 3G and EDGE?

EDIT: You know, I asked, but I don't think the answer matters. It shouldn't be a problem. Triangulation is for when it can't find a signal because you're indoors. There should be no problem getting a clear signal for a bike ride so I doubt that ever comes into play.

GPS shouldn't be any more accurate with 3G on or off. The only thing that will be quicker possibly is when GPS finds your initial position.

I know it does use triangulation, but not sure if it uses the 3G signal to do so or not.

Once a gps lock is made it makes no difference.

The gps in the iPhone is A-GPS or assisted GPS. The GPS is performed quicker with the aid of the wifi triangulation and cell tower triangulation but when a lock occurs you dont need any connectivity at all. I do the same with runkeeper, a workout tracking app, I turn airplane mode on and my distance and running map are perfect.

It uses 3G or EDGE for triangulation (as well as any wifi hotspots).

Good to know. Although, aren't you afraid you'll miss a call?!? 😱 😛
