RE: [amsat-bb] Spin Rate & Attitude Determination from WOD

[paul.willmott@xxxxxxx]

Hi Gilbert,

Yes the spin value in the telem is incorrect, ... and has been since launch
.... 

The WOD data format for AO-40 has not been written up yet and published,
however it looks almost identical to AO-13 WOD format, ... you can find the
details on how to decode it at:

http://www.amsat.org/amsat/ftp/satinfo/ao13/spec_wod.doc

You can find how to use this data by reading the following article on AO-10
attitude determination, ... AO-40 is identical to AO-10.

In looking at the 12 January telemetry from A0-40, the spin is 
reported to be 0.891rpm.  Does anyone know if this is a correct 
reading or if this value is in the process of being calibrated?

I also noticed that the "L" and "K" blocks are WOD captures of 
channels 0x019B 0x019D. Which are spin count at the edge for upper 
and lower beams.
