> Before there was GPS, there was the U.S. Navy Navigation Satellite System 
also known as Transit. Transit was decommissioned in December 1996 because it 
was deemed no longer needed in the GPS era, but this first global navigation 
satellite system transformed navigation and geodesy and provided valuable 
inputs for the development of GPS.
> 
> Recently, some interesting videos have appeared on YouTube documenting the 
development and operation of Transit:

> "Transit: Three Decades of Helping the World Find Its Way" (1996)
> Produced by The Johns Hopkins University Applied Physics Laboratory, the birthplace of Transit.
