[aprssig] Satellite positions: Objects or Stations?

Would it be sufficient to include a ,KJ4ERJ-15*, in the path?  Or is the 
qaC,KJ4ERJ-5 that is added by the APRS-IS server sufficient?  I hate to 
clutter up the comment that everyone sees with information that is only 
there for tracing purposes.
