I'd assume this thing having been launched in 2005 has enough memory to hold imagery for the entire planet so one wouldn't have to be in the region they want data for. That's my assumption and it seems to agree with the data.
- RX14 11y agoNo, these satellites only send out the line of pixels directly below them. For example if the satellite is moving south, your image is rendered from the top down, but from the bottom up if the satellite is northbound. These satellites are very basic, and that I find is part of the fun.
- oxplot 11y agoOK, then in that case I managed to receive the signal from a satellite 800km above but passing over the other side of the planet. How's that explained?
- joushx 11y agoYou got a very noisy signal without much information (the gray thing in the background) with an random map overlay generated by wxtoimg. Try to hide the map overlay and you should see the picture you really received.
- oxplot 11y agoI am aware what I received (and it's not what you described). I was asking how I could receive a signal with the entire planet blocking the way.
- aeroman 11y agoDo you know what wavelength you were receiving? I would expect to see some clouds. Northern Scandinavia was a bit cloudy today. http://oiswww.eumetsat.org/IPPS/html/MSG/IMAGERY/IR039/BW/WESTERNEUROPE/index.htm http://oiswww.eumetsat.org/IPPS/html/MSG/IMAGERY/IR039/BW/WE...
- oxplot 11y agoDo you mean the frequency? I googled NOAA 18 and Wikipedia told me ~130Mhz.
