It will have absolutely zero trouble locating your position from the inside of a batterygrip. Just like WIFI and Bluetooth won't have any problems operating from there.
It is a well known fact (and there is even research, both scientific and from "consumer-protection-groups"
to support it) that the more is put in a smartphone, the less it seems to perform in it's basic function, i.e. making calls.
I am one of the rare `Homo sapiens non-smartphonus` and I have a phone that I can drop, let get wet, be dusty, hardly takes pics, has a tiny screen and I can make calls where no man can make calls. I just does not break. And I can do without charging battery for days...
GPS in a phone is usefull because most of the time it is always on, therefore always in touch with GPS satelites... If you have GPS in your camera, you loose contact with the satelites everytime you switch your camera off, so it needs to lock on everytime you turn the camera on, which may take a while depending on where you are. Unless ofcourse there is a `GPS stand-by`mode which drains the batteries....
Just a camera bag with a map pouch and a map will do fine...
