Yeah, my first thought when I ran across that HPJ article was, wow, even the first satellite had -- an oscillator! The other thing to note is that the combination of Sputnik and Dr. Peterson (at Stanford) were the "space segment" and "user segment"; two phrases familiar to anyone reading introductions to GPS. No "control segment", however. If 40-year old Sputnik (quartz in space) is the grandfather, is 30-year old NTS-2 (cesium in space) the father of GPS?
