iPhone accuracy?

[+Cockney_Pixie]

How can I get complete accuracy with my iPhone? Anyone know of any good apps that are really accurate at pin-pointing my position?

 

I find that the 'maps' app and the 'geocaching' app co-ordinates are always about 20-40 metres wrong! Really frustrating now that I want to set my own caches....

I hear you on this. The I phone 4 uses (Assisted GPS) which means first there is a receiver antenna chip that receives at least 1 satellite signal. then there is a server that in lay terms triangulates and uses current cell tower locations and locks your position faster than a normal satellite only receiver.

 

I have noticed on my iphone 4 that I receive coordinates that can vary greatly depending on the surroundings. I find the Iphone 4 useful but I rely on my Oregon 450 that receives 12 satellite signals and I use the Iphone 4 as back up and sometimes in conjunction with the Oregon when I am on the hunt.

 

I am not a satellite expert but did read a little.

There are some accessories that help to improve accuracy. Problem is they are rather slow to update your position. But for the same price as some of those you can get a decent Hand Held GPSr that will give you an accurate position. THen you can use your iPhone to go peperless.

Why not ask in the UK and Ireland side of the forums, where UK cachers can let you know what works, and what doesn't, in the UK.
