No, GPS does not use data of any sort. It collects information from signals that are continuously sent by satellites, along with a bit of math, to find your position. However, if combined with a data consuming application, it will use data, but it's not the GPS, it's the app. For instance, Google maps will use data to stream the map so that GPS can show you where you are, that is, unless you saved the part of the you need to your phone using wifi beforehand (using "make available offline" in the setting menu of Google Maps).

GPS does use data. It has to contact the network and then download that information into the phone for the map information to be displayed. You cannot actively use a GPS system on a phone without turning on mobile data. That being said, you could download the data before hand so that information is on the phone. There are various apps that allow you to do this, which can be downloaded over wifi.

Alex, download an app like Navfree. I used it while traveling in the US last month and I didn't use a drop of data. You'll need to download maps before you travel but after that, there's no using your data. https://play.google.com/store/apps/details?id=com.navfree.android.OSM.ALL&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5uYXZmcmVlLmFuZHJvaWQuT1NNLkFMTCJd
