Iphone thinks Im over a mile away!

Hi,
My iPhone thinks I'm over a mile away from where I am.
The strange thing is when it location tags my photos it get it correct (99% of the time) but google maps and the emergency beacon app are incorrect.
The emergency beacon app just gives me my coordinates but these are in exactly the same place that google maps places me.
I do a lot of sea kayaking and was glad to have this feature on my phone in case the worst ever happened but now I think it may become more of a hinderance.
Anyone know of a way to fix this?

 

Yes. Its a free app.
Its not quite what I was hoping for.
It just gives you your coordinates and then gives you the option to email them to somebody.
