All of the AO-40 telemetry is archived on the AMSAT website. You can
For November 17 at 15:11 UTC you probably want the file
for the corresponding telemetry from that day.
For the satellite's position, you can use the then-current TLEs from
earlier that day
which are in the file
Almost every telemetry zip file contains a .TLE file with the NORAD TLE
that correspond to that telemetry. For example, the file
contains AO40_NORAD_SET_3.TLE which contains the then-current TLEs.
Those TLEs were only a few hours old when your recording was made. If
load those into a prediction program you can get the satellite's
If your telemetry data from your recording is not already in the
I'm sure we could get it added as a late submission. Let us all know
if your data
is unique! If you're not sure, send me what you copied or send me the

Subject: [amsat-bb] Deciphering Phase 3D Telemetry
I found a recording I had made of OSCAR-40's beacon on an old hard
drive. I decoded the telemetry with AO40 RCV and found that it dates
back to November 17, 2000. The status window shows that AO-40 was on
it's third orbit at 15:11 UTC.
I'd like to know the position of satellite when the recording was made
and was wondering where I can find an accurate set of old Keplerian
