The Space Show: Interview to Roger Easton
This interview blew my mind. Roger Easton was not only the designer of the Vanguard 1 satellite, but he also conceived and led the development of GPS. Since Position, Navigation and Timing (PNT) is one of the main sectors in space industry, I truly recommend this interview.
