Now See Graph of Altitude and Signal Strength on Mode-S data.

I've been making some improvements to the Raspberry Pi / RTL Dongle Mode-S Logger setup.

I now store all altitude and signal strength info for every Mode-S message received from a Military Aircraft
and present this data on a nice graph display.

If you go to my Live Military Mode-S Logger page here:
http://milaircomms.com/mil_air_modes_logger.html
and click on the Mode-S Hex code you will be taken to a Flight Profile page for that Mode-S Aircraft. Here the altitude and signal strength are graphed for the duration of time Mode-S messages were received.

Soon I will be making the Raspberry Pi software available free of charge where you can either independently or simultaneously send your Mode-S data to my Mode-S logger page and/or Virtual Radar Server.  When sharing to my page you'll be able to print logs of your data to share with your friends or get text messages to your cell phone any time a military aircraft is within range of your receiver.

Here is a link to a nice plot I got today: http://milaircomms.com/hex_code_profile.php?hex_logger_id=120484 Its of an Army UH-72A, picked him up at 450' ASL, the system graphed 364 Mode-S messages from him until I lost his signal at about 4,000' ASL.

Take a look, comments or suggestions always welcome.

I've now seen a great use for my own invention. 

Today I saw 8 KC-135's come up on my Real-Time Mode-S display.  While none were sending lat/long I still could get a picture of what they were doing.

It start out with 4 KC-135 flying level, as seen in the attached picture they started a climb at same time (are they flying formation?)  These will be the 4 bottom for graphs/planes on the picture.  Then soon after, 4 more KC-135's come into range.  They do the very same thing...  I'm sure that would have been a great site to actually see 2 flight of 4 each KC-135's information
