I friend of mine sent me this clip, mostly to make fun of my 90’s computer monitor and 90’s hair. Regardless, it’s interesting to see how widely accepted #GPS technology has been accepted.

Some of the higher end telematrics systems have redundancy built in with the other navigation systems out there – BDS, Galileo, GLONASS. I am sure US DoD has redundancy we know nothing about. Aircraft and maritime navigation have radio and manual backups.
