Another look at Yubileiny

In an earlier posting, I presented a recording that I did of the new Russian satellite Yubileiny, also designated RS-30. I finally found my spectrogram code, and made a picture of the resulting recording. It's kind of big, but click the thumbnail below if you want to have a peek:

Recording of Yubileiny on May 27, 2008

The image consists of 27 spans, each of about 30 seconds. You can see that every five seconds, my program corrects for the doppler shift, perhaps causing a break in the morse line. It's relatively easy to read the morse code off the resulting image.



Platypus is a system that can convert scripts (shell, Python or even perl) into something that looks a lot more like a real Mac application. I have a number of potential uses for it to pretty up some of my scripts, so I'm bookmarking this for now.
