From time to time I've read about some interference, or deliberate jamming,
of an amateur satellite.



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.



Since the satellites are in highly elliptical orbits the Doppler Shift would
be different over several orbits. Then using multiple orbits these curves I
think would tend to intersect, or nearly so, at one point. Additionally the
time of signal acquisition and loss can be timed and compared to the
projected ground foot print of the satellite coverage zone to help zero in
on the source location.
