Spin Data Plotted! 3 RPM perfectly about Z as induced by differential radiative pressure.

See plot:

Now to see if it keeps spinning higher or has achieved equilibrium with eddy current damping…

Got good Spin packets from J

Finally Got spin data from JA0CAW And PY2SDR!

Since we have not yet written any decode software, we will be manually processing these.

The format is OOOOmm,0z200,XYZXYZXYZXYZXYZXYZ…..XYZ

Where OOOO is the orbit number and mm is the MINUTE (0-to-95) into the orbit.

0z200 is status, ill do later…

Tha Alphabet soup is the sun vector data over the last minute! In this case, every 5 seconds, Where the XYZ are the values of the XYZ sun vector. CAPITAL letters are from +1 to +26 and lower case letters are from -1 to -26

This 4th packet below shows the satellite just coming into sun. What an amazing coincidence

Make a scale going positive from 0 to Z and negative from 0 to –z. Then for each XYZ set, plot the three points. Then connect the X’s and the Y’s and the Z’s and we should see a pattern of rotation!

Im starting now. By tte time I finish, a good programmer might beat me to it!
