hmm.. well if you only just recieved it, a hard reset wont hurt.
In your settings there will be an option saying something like wipe device or memory or something like that

did you get this phone used or new?

cause if its used then a hard reset is a great way to get a feeling of a brand new phone out of your decice since it will all go back to a day one image of the operating system.

if its new, well then there might be a bug in the gps program and a hard reset might fix it non the less.
