DIY satellite imagery OCT 31 2011
With a computer, some software, and a couple hundred dollars of hardware, you can pull down your own satellite images from satellites managed by the National Oceanic and Atmospheric Administration.
The National Oceanic and Atmospheric Administration (NOAA) manages a few satellites in low earth orbit. There are three actively transmitting APT signals at the moment, NOAA15, 17, and 18. Each of these satellites passes overhead a few times a day. I've been interested in learning how to receive their signals for a while now, and I've finally succeeded!
