ARISSat-1 in SATPC32



Hi,  

The deployment of ARRISat-1 is approaching.  Here is a collection of data on
the various modes for use in configuring SATPC32.  Note that you will need
to tweak the sideband frequencies slightly to account for rig calibration
and other issues, as usual, but these should be close.  You can paste these
in the DOPPLER.SQF file, but before you do, please read on!  

ARISSat-1,145918.5,0,USB,,,0,0,BPSK/CW-2
ARISSat-1,145950.0,0,FM,,,0,0,VOICE/SSTV
ARISSat-1,145930.0,435750.0,USB,LSB,REV,0,0,XPDR
ARISSat-1,145938.5,0,USB,,,0,0,CW-1

Since ARISSat-1 will be deployed by a gentle push from the ISS by
Cosmonauts, the ISS Keps will be good until separate Keps are released by
Space Track.  One way to handle the transition is to change the Doppler
information slightly:

ISS,145918.5,0,USB,,,0,0,BPSK/CW-2
ISS,145950.0,0,FM,,,0,0,VOICE/SSTV
ISS,145930.0,435750.0,USB,LSB,REV,0,0,XPDR
ISS,145938.5,0,USB,,,0,0,CW-1

Paste the ARISSat-1 data as desired, and also paste the ISS version of the
data into the DOPPLER.SQF file after the regular ISS data. For the final
test aboard the ISS, and initially after deployment, select ISS tracking,
and then select the desired ARRISat-1 frequency data at the end of the list
in the CAT window.  

After the ISS and ARISSat-1 are far enough apart that independent Keps are
available, you can begin using ARISSat-1 as a separate object by adding it
to the objects you track in the Satellites menu window.  The satellite may
be identified as ARISSat-1, but may well have some other designation which
will be reported.  If it is not ARRISat-1, then change the name in the first
group above to that used in the Keps.  They must agree exactly for SATPC32
to match the Doppler data with the satellite.  (You can also use the
AmsatNames.txt file, which is covered in the SATPC32 documentation.)  You
can then delete the extra ISS data if you wish.  They won't hurt anything,
but it will clean up the ISS CAT window.
