My question is has anybody written a nice paper where using known orbital
elements of the satellite and Doppler Shift to calculate a curve on the
earth's surface where the source maybe located? I would think any issue with
the satellite's transponder's frequency conversation, due to local
oscillator frequency drift, can be corrected for by calibrating the link
between two or more known stations. This I'm assuming would likely only work
for linear transponders.


This is how the SARSATs calculated the position of 121.5MHz and 243 MHz
EPIRBs.
