Yeah, I couldn't find the UHF downlink polarization, I'll try using an OSCAR
(435 MHz) RCP yagi
http://www.poes-weather.com/~patrik/AO-51/OSCAR%20Yagi%20007.jpg
It seems to pass FI at zenit tonite Jan 21st 2350Z
The downlink seems to be 437.270 MHz. I'll use the TVRX, USRP1 and the
usrp_nbfm_rcv.py in examples
Thanks,
Patrik

Hi All,
Is it linear polarized, if so which?
If not, then which circular polarisation?

I don't know, but this, from the Nansat-D mission dashboard, is not very
hopeful:
"
STATUS: NanoSail-D ejected on 1/17/11 at approximately 1900 PST. Beacon data
was routinely received by the public throughout the world from 1/19-21/11, and
telemetry indicates that the sail deployed on schedule. As of early morning
PST on 1/21/11, no beacon packets are being received. This combined with a
plunging battery voltage may mean that NanoSail-D is effectively out of power.
The ops team and amateur radio operators around the world are still making
attempts to make contact with the spacecraft.
We will be tracking the de-orbiting of NanoSail-D over the next few months,
and we will post any available visual photographs of the satellite, which are
being collected by the mission team at NASA Marshall Space Flight Center."
