Re: [Discuss-gnuradio] HRPT receiver

[Marcus Müller]

Hi Pablo,

Googling "Noaa image format" instantly yielded:
http://commons.wikimedia.org/wiki/File:NOAA_APT_Frame_Format.gif
http://www.sat.dundee.ac.uk/hrptformat.html

It's already been done a few times - for example like this (really just googling "GNU Radio NOAA image decode" and clicking the first thing away...)
http://www.oz9aec.net/index.php/gnu-radio/gnu-radio-blog/350-noaa-weather-satellite-reception-with-gnu-radio-and-usrp
but here, Alexandru Csete used a GNU Radio-Based flowgraph just to record the received signal to a Wav file and process it via atpdec
http://atpdec.sourceforge.net/
and, honestly, how cool would it be if you wrote a small piece of GNU Radio software that had a signal sink, which used the atpdec code and displayed images in a window? (Hint: awesome).

So:
Happy Hacking,
Marcus

Hello, 

I was wondering if someone can receive hrpt images from NOAA satellites or similar, if so, could you help me with the implementation of the receiver? There is not quite information about that format, so if you could help me I would really appreciate it.
