Packet radio downlink from the International Space Station (RS0ISS) received on 10 July 2010 20:15 UTC. Received using an Arrow II antenna, Universal Software Radio Peripheral (USRP) with WBX daughterboard and GNU Radio software defined radio receiver. Decoding was done using multimon software modem.
This video tutorial explains how to connect the output from GNU Radio to the input of multimon using a Unix pipe: http://www.youtube.com/watch?v=GBmli8Vflig
You can also see the linear transponder downlink from the VO-52 satellite. If you want to listen to it see this video: http://www.youtube.com/watch?v=Y4x-LpCs918
The SDR receiver software is available here: http://www.oz9aec.net/index.php/gnu-radio/grc-examples

Hi, i would ask you something, did you use some kind of tracking or something like that to follow the ISS?
PS: another one, i'm new with the USRP, so sorry if the question is a little bit stupid but, did you build this software by your own (with GNU radio) or is an already built one?
Very nice work
(And sorry for my english)

@Shephard1986 I use Gpredict for satellite tracking. The FM receiver I built using GNU Radio Companion application which is part of GNU Radio. GNU Radio is a toolkit for building software radios but it also includes many examples ranging from simple FM receiver to digital data transmitters and receivers.
In the video description you will find a link to the FM receiver.
