The D5 doesn't have built in GPS, and adding it requires an attachment. I don't know if the smartphone app works on that model, but it is from the same year as my D5600 which does support it. The app provides GPS but also drains the battery fast. I turned airplane mode on after the first dead battery.

GPS might work out there though: https://www.nasa.gov/directorates/somd/space-communications-...
