FYI,
There is also a cross-platform POES/GOES LRIT/HRIT spacecraft decoder
work-in-progress
Screen shot http://www.poes-weather.com/~patrik/1.7GHz/POES-USRP-Decoder.jpg
At the moment it does the following:
- render NOAA POES HRPT imagery
- render decompressed GOES LRIT/HRIT full disk imagery
- realtime satelellite tracking and prediction
- LPT rotor control support
- antenna AZ/EL HID device sensor support
I have not yet bothered to make a HOWTO web-page but soon when it gets
warmer up here North....
It is built using Qt Creator
If you are interested, checkout the latest revision from and do a build
svn checkout
http://noaaport.poes-weather.com:8081/subversion/hrpt-decoder/branches/1.0.0.2/
View the work in progress at
http://noaaport.poes-weather.com:8081/viewvc/branches/1.0.0.2/?root=hrpt-decoder
Warning, it is a VERY work in progress SW,
Patrik

Great choice! I have used the USRP to receive NOAA APT signals before
(with one of Jerry's antenna designs it seems, incidentally). Very
curious what he is going to do with it :)
BTW, the (newish) gr-noaa component in GNU Radio can receive and
demodulate the AVHRR/HRPT 1.1 km/pixel telemetry from NOAA POES
spacecraft. There is a crude Matlab/Octave rasterizer script to turn
the telemetry into B&W PNG files for each imaging channel, or the output
can be read directly into a commercial HRPT rendering program like
HRPTreader for more sophisticated false color image generation.
