Does anyone know if the TLE used by heavens-above is current for AO-40?
http://www.heavens-above.com/orbit.aspx?satid=26609
I understand that it is still dead in its orbit, but it might be a
useful task to have an otherwise-idle SatNOGS rotator, antenna, and SDR
watch it for signs of life.
Thanks!

It gives the Epoch for the Keps as:
Epoch (UTC): 21 September 2017 01:11:23
So that would be a yes.

New subject: [amsat-bb] AO-40 orbital elements
I was thinking of this a while back, has a command station attempted to
contact it recently?
Unlike AO-7 my understanding is that it will not just 'wake up' and start
beaconing as the transmitter (either V or U) that was that failsafe
transmitter is non-functional.
So without intervention to turn on a S band TX if a cell was to open up,
it'd just sit their quietly. Is that a correct understanding?

I’m not the expert but it is my understanding there was possible an explosion or something
similar that crippled it.

Chad,
You are correct: The working hypothesis is that an explosion damaged the
main battery, which failed into a shorted condition.
https://www.amsat-dl.org/journal/adlj-p3d.htm
As we've seen with AO-7, it is possible that the battery could go from
short to open in the future. Might as well be ready for the day that
happens!

Totally agree. It would be great to even hear a blip from it.

New subject: [amsat-bb] AO-40 orbital elements
W4SM was kind enough to provide the following information:
The most you could hope for would be a carrier on the
S2 middle beacon frequency,
which I can’t recall off the top of my head, but I think it was about 2401.3 +/- MHz. All
the other transmitters were dead.
Given how many times AO-40 has gone through the radiation belts on its Molyniya orbit,
I would doubt that the IHU would be functional at this point.
So, it may, someday, have power, but it may not have any brains to do
much with that. We can still hope!
A great technical article about the IHU-2 onboard AO-40 is located at
http://www.amsat.org/articles/g3ruh/124.html, and dovetails into a
presentation that our little AMSAT ASCENT group will be making at the
Symposium. See ya there!
