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. |
