+-- This code was originally written by Miami Mike to calculate the Open Location Code (Google+Code)
+-- It was altered by ChrisOhara to permanently store the last received GPS coordinates by background function.
+-- So that it can display the last position as Google+Code even after connection to receiver is lost.
+-- Works on taranis
