I'm running an iphone 5S and an app called Tomstrails. I have verified the latitude and longitude on Itouchmap.com and it is within 8 metres of where I am sitting. Tomstrails says it's 65m accurate. I am sitting in an old stone barn.

Cheers for the link!

Tbh I'm now starting to think it may be a problem with my phone, I just downloaded toms trails and switched it on. Left my phone by my bedroom window. After 30 mins plus it couldn't get a fix on my location!!!

I checked all the settings first, and they are correct, but it keeps saying waiting for satellites!!!

Do an iCloud back up and reset your phone as a new phone. That should rule out anything software related.

The iPhone has several non-obvious settings that can change the behaviour of the GPS. I would do as Countryman suggested and backup the phone, do a complete reset and test the phone without restoring the backup. You should try outside to give the antenna the best chance of seeing the required number of satellites. Contrary to popular belief, the iPhone does not require a phone signal to get a position.

Good luck with your problem.

IMHO, buy a separate GPS.
why? because if your batteries in one device dies, you will still have the other.
gpsphone dies? not only will you get lost, but you won't be able to call for help either...
either that, or buy a good compass, and learn how to use it. :)

Carry a spare battery and/or a USB power bank.

So, I have to ask. Are you the software designer?

Yes, its does on modern smartphones you dont need a phone signal for the gps to work

A GPS receiver uses the signal from the GPS satellites to calculate it's position relative to the satellite, but it needs to know where the satellite is before it can give you a physical location. That's the time consuming bit because the satellite position data, or GPS Almanac, is downloaded from the satellite and can take several minutes to acquire. The almanac can be received over the cell network much faster, known as A-GPS and that is why a smart phone often gets a fix faster than a dedicated GPS. A phone will work without cell phone coverage the same way that a dedicated GPS does. The almanac is valid for some time so if you run an app that uses the GPS earlier in the day, you will have the data before you get in the wild.
