This is actually pretty cool. I last worked with satellite data from GOES 8 and 9 in '98. I remember satellite images were sent sent every 3 hours and full disk images were 12 hours. I worked in a weather office where they had one pc running DOS that received the data from Satellite and saved the data where various HP-UX servers manipulated the data.
Last i remember, all data transmitted by these satellites are not encrypted, anyone can build a receiver to gather the data to generate satellite images.
One day I hope to have time to do this myself.
- aeroevan 10y agoI currently use an SDR to capture ADS-B messages, but it can also be used for satellite images fairly easily: http://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weather-satellite-images/ http://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weath...
- edsouza 10y agoThanks for the link to that site. GOES weather satellites use a different format. Found the beginning article to the series here: http://www.rtl-sdr.com/setting-up-a-goes-weather-satellite-antenna-system/ http://www.rtl-sdr.com/setting-up-a-goes-weather-satellite-a...
- woodman 10y agoIsn't there a lot of work that goes into post processing the data? It wouldn't matter if you just want an awesome background image, but using the data for some kind of actual work... there is a lot of calibration to be done. I was working with some ESA Sentinel data several months ago - not fun. Edit: For those who don't normally work with this stuff, I'm talking about not only correcting geospacial data - but also bringing the sensor data in line with a bunch of other sensors and past datasets. It quickly goes from "Oh, pretty pictures!" to "Do I really want to do this anymore? Can I ever trust data again?" That said, doing your own ground segment is cool - just know that there is a whole lot more work to do beyond actually receiving the radio transmissions. https://earth.esa.int/web/sentinel/level-1-post-processing-algorithms https://earth.esa.int/web/sentinel/level-1-post-processing-a...
