Could be, I seem to remember reading that when at the far north latitudes, you might be able to catch a signal from orbiting satellites on the other side of the pole. I don't remember seeing any restrictions based on latitude in general GPS info.
I have used a GPS, aftermarket installation at the exact north pole and there was no difficulty. I have not heard anybody mention difficulties at the south pole which is a much busier location with a frequently used airstrip during the summer.
