I found a Bliley 10MHz OCXO model NV47M1008
Anyone here know about these? They seem to be available for about
$11.00 or so.
I looked around on the web and found specs for units that are "kind of
like" this but not this exact model.
You can see one at eBay #171274003103
Thanks,

I just red somewhere that the last "ping" was the only one recorded by
Inmarsat system, Pings up to that point were presumed to occur due to
known reporting intervals. So there is no "track".
The Inmarsat data is a red herring. The plane could have ditched into
the water 85 minutes after the "
I wrote two new ADEV command line tools that some of you may be interested in.
adev4 calculates adev for a linear range, from tau to tau step tau.
adev5 calculates adev for a logarithmic range, from log(tau) to log(tau)
step log(tau).
The both calculate ADEV, MDEV, HDEV, or TDEV.

The point is that they might have been able to do more precise pings
in real-time, but now that it's on file i
Missing plane this ping was not lost why would others be lost ? This ping
was retrieved long after (days) it was received why would it be the only one
?

They might have been able to do that while the plane responded, but
now that the plane
