I've been preparing for the CubeSat release from ISS scheduled for
tomorrow. Hope it happens!!
For my simple brain, I've figured an easy way to get the frequency
tracking/Dopper, etc entered into SatPC32.
First, we can use the ISS Keps for tracking--at least for a few days
probably, until Keps are released by Celestrak, etc. I already have
that working (don't you?). So, no need to do ANYTHING with Keps--just
make sure they are "fresh."
Second, there is the matter of frequencies! So, I entered the
following into my Doppler.SQF file:
ISS,145980.0,437485.0,FM,FM,Nor,0,0,F1 1k2 AFSK packet
ISS,437485.0,145980.0,FM,FM,Nor,0,0,F1 CW telem over FM
ISS,437250.0,145980.0,CW,FM,Nor,0,0,FITSat1 CW telem
ISS,437445.0,145980.0,FM,FM,Nor,0,0,FITSat1 1k2 AFSK packet
ISS,437505.0,145980.0,FM,FM,Nor,0,0,WE WISH 1k2 AFSK packet
Now, all I have to do is track ISS (in normal SatPC32--don't use
SatPC32ISS!), and using the "CAT" menu select the frequency of the
CubeSat I want to listen to. If you look at the text line at the
bottom of the box, you'll see why I put the CubeSat name at the end of
each line above...
Easy to do, no need to worry about "launch Keps", etc. We have them already :)
Remember, the "upper most" line is one that loads by default. For me,
that's going to be the F1 1k2 AFSK FM packet signal.
Also, after we DO get real Keps--all you have to do is edit the
appropriate ISS with the name of the bird; make sure it's the same
name used in the Keps (or get fancy and use the AmsatNames.SQF file).
Hope that helps some of you...
