Site Origin of 0
VIPS normally outputs locations in degrees latitude and longitude, if however an origin of 0,0 is given, then the
conversion to latitude/longitude is skipped and the VIPS rover will output in meters X,Y. When operating with a VB3i, an
origin is always needed, when operating in standalone mode, this is optional.
