15000 planes with 25M positions as seen from outerspace


I found this on the website of the European Space Agency. Doesn’t say if these are the planes tracked within 24hrs, 1 cycle around earth or the whole time it has been up but it sure has some nice coverage. Makes me wonder about a new antenna :laughing:

On the ESA site you can also find a nice High-res(1024x2048) version of the picture as well.


Time to buy a weather balloon to increase reception! :wink:



Did they use a Raspberry Pi+ Dongle based receiver?


The article that I read presented these numbers as the totals from the two years that it has been operational. It seems a lot less impressive when you look at it like that.
