You see, the вЂњscanningвЂќ is the cylindrical satellite spinning around, nothing more. ThatвЂ™s it! Pictures taken just hours ago? Totally incorrect! You are actually receiving the data milliseconds after it is gathered, there is (or, was) absolutely no data storage or buffering. Hardware? A single cable connecting the radio earphone jack to the laptop audio input jack. Helical antenna, circular polorization? Hogwash! I used an actual bent coat hanger whip antenna, and got very nice images, thank you very much.

I used a very cheap little radio, sold by Radio Shack, for listening to aircraft talking to ground control, subsequently thrown in the trash by a bored user. Actually, no hardware вЂњdecodingвЂќ is needed. вЂFunny seeing this coming вЂ™round again! I did all this about 30 years ago. Posted in Radio Hacks Tagged RTL-SDR, RTLSDR, software-defined radio, weather satellite Post navigation вЂ™s use of a USB TV tuner toВ receiveВ the transmission from NOAA satellites is a lot easier on the pocketbook, though, with the largest expense being an investment in time to build a helical antenna.

This isnвЂ™t the first time weвЂ™ve seen images from a NOAA weather satellite downloaded with a software defined radio last yearВ did just that with a somewhat inexpensive Softrock SDR. A somewhatВ specializedВ antenna is required to receive the right hand polarized transmissions from NOAA weather satellites, but with a few bits of wood and wire, made a helical antenna to listen in on the weather satellites transmitting around 137 MHz.В After gathering a whole bunch of data from the satellites with SDRsharp, used an image decoderВ to turn an audio file into a picture taken from space just hours ago. To get these near real-time satellite pictures, used one of those USB TV tuners weвЂ™ve grown so fond of. These transmissions arenвЂ™t encrypted, and given the requisite hardware itвЂ™s possible for you to download these images from space as shows us in a tutorial video.

Several times a day, a NOAA weather satellite passes over your head, beaming down pictures of weather systems and cloud formations.
