It's interesting to tracing the path from the doppler data which was used to determine the slant range between he satellite and the receiver antenna. The data on your web page doesn't seem to show the actual doppler shift numbers. Do you have that data? Some cleaver thinking then leads to the idea that you can determine were you are if you know the satellite orbital parameters. That's what they did at John Hopkins University thus starting the Transit program for Polaris subs. http://sd-www.jhuapl.edu/Transit/index.html But Transit required atomic clocks so in the next generation sattlite nav system the atomic clocks were designed out and we ended up with GPS. I think it's more than fair to say sputnik is the grandfather of GPS. more at: http://www.prc68.com/I/electron.shtml#Sputnik Have Fun, Brooke Clarke http://www.PRC68.com http://www.precisionclock.com http://www.prc68.com/I/WebCam2.shtml 24/7 Sky-Weather-Astronomy Cam Tom Van Baak wrote: > > A little known piece of Sputnik history... > > http://www.hparchive.com/Journals/HPJ-1957-09-Sputnik.pdf > > /tvb > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. > _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
