Re: [Discuss-gnuradio] NanoSail-D turns out isn't lost!

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."
