Yeah, I couldn't find the UHF downlink polarization, I'll try using an OSCAR (435 MHz) RCP yagi
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

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."
