Aptdec is a FOSS program that decodes images transmitted by NOAA
|
|
weather satellites. These satellites transmit constantly medium
|
|
resolution (4km/px) images of the earth over a analog mode called APT.
|
|
These transmissions can easily be received with a cheap SDR and
|
|
simple antenna. Then the transmission can be decoded in narrow FM mode.
|
|
The input audio format can be anything supported by libsndfile
|
|
(although only tested with WAV and FLAC). Sample rate doesn't matter,
|
|
although lower samples rates will process faster.
