GPS worked fine all the way from Australia to Hawaii

This video shows my Bad Elf Pro GPS recorded a seamless log of the flight from Sydney to Hawaii. GPS works fine everywhere.

It seems many people are confusing the information they see on flight trackers like FlightAware and Flight Radar. These trackers can rely on ground based installations that receive information from the Aircraft, Radar and ADS-B. When the aircraft flies out of range of a ground station it will appear to "drop off the radar" on these simple flight trackers. The GPS is a one way system that provides location information to the aircraft and pilot. It has no tracking capability at all.

GPS works fine everywhere in the world.
