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 - I will be posting more videos to prove this. 

The Radar and ADS-B based tracking systems do not work over the oceans.  When flying over the Oceans the aircraft position is tracked by ATC based on either HF radio position reports by voice from the pilots or by ACARS if the aircraft has this fitted.  It will electronically send a position report to ATC. 

The free online flight tracking programs have no access to HF voice position reports or ACARS down linking which is why those trackers show the aircraft disappearing once off they move a few hundred miles off the coast.
