Re: Satellite ranging



Myself, I have often triggered an oscilloscope with a GPS generated 1PPS and 
displayed the 7 kHz timing pulse from low orbit Russian Tsikada satellites 
(149.040, 149.070, 150.000, 150.030 MHz) to watch the range close, reach 
closest point of approach, and then recede in distance.
