Build Your Own Satellite Ground Station
kavachameleon writes "A site called Hobby Space has this article at which there are instructions on how you can build your own satellite weather station! Something I think all of us have wanted to do at one point or another, this site tells us all how to "hack" into the weather satellites and get back usable pictures using our PCs and an AM antenna. There are more instructions for getting geostationary images."
I've been reading articles about how to decode these pictures since the 60's - I've got ARRL books and magazines going back at least that far. Hobbyists have been doing this with PCs since the late 70's. The transmissions are basically faxes, so it's pretty easy to decode with a sound card.
I know there have been some old news stories appearing lately, but really now...
Once again slashdot stumbles upon an already popular hobby. http://www.scnt01426.pwp.blueyonder.co.uk/Articles /WXSAT/wxsat.htm
We use it all the time in Antarctica. I'm sure it is useful other places not covered by weather.com. You have to have line of sight on the sat, it has to have line of sight on the weather, so the range is limited, but good enough. The pixel size is huge, so it's no good for spying.
It does do both IR and visible, so you can get the temp/height of the clouds too.
'SBEMAIL!' is better than a goat!!
I ported the wx200d communication code to BSD a year ago. Good software!

You have to remember these are weather satellites. An extreme high resolution image is not yet available, even with professional equipment. The GOES series satellite have a 1km per pixel resolution for the current GOES 8 and GOES 10 satellites. In about 10 years 10m or possibly 1m resolution satellites are going up. With the American Goes satellites it will not be possible to watch the irag decimation. They simply aren't in a place on the Earth where they can view it, and GOES 8 will probably being moving even further away in April. None of the GOES data is encrypted or delayed so an instantaneous feed is available, but keep in mind it can take anywhere from 5 minutes to 45 minutes for an image to be completed depending on the region of the earth being scanned. Also keep in mind that you'll need software that understands the GVAR format in order to see the data from the GOES satellites. I work with these satellites everyday, it is non-trivial without the right software to use the data.
