Logsat 5.1 Y2K tweaking



-----BEGIN PGP SIGNED MESSAGE-----


So, MIR isn't really 7000 kilometers high...

I downloaded a fresh set of Keps
from

http://oig1.gsfc.nasa.gov/scripts/foxweb.dll/syspage@app01?tdac=V9VB6Z2E
OZDZY0PU35FB

(watch for line wrap in the URL).

Not all of the Keps are for the 2000 epoch yet, but the one I chose for
testing was MIR in the file INTEREST.TLE (from GROUPTLE.ZIP).  Here it
is:

MIR
1 16609U 86017A   00001.50334991  .00075662  00000-0  32123-3 0  2127
2 16609  51.6565  43.0853 0004483 208.7859 151.2889 15.84607492792685

In Logsat 5.1, I went into 'Satellites>Satellite elements>Delete
satellites' and deleted *every* satellite except the sun from the
database.  Then I read all elements from INTEREST.TLE.  After doing
this, I compared the track for MIR with NASA's JTrack page at:

http://liftoff.msfc.nasa.gov/realtime/JTrack/Spacecraft.html

It appears right about where NASA says it should be.  Looks like Logsat
5.1 may work for us after all, the key seems to be cleaning out all the
old Keps because it doesn't update properly if they are still there.

Note, however, that if a satellite has a different name, it will stay
on your screen in the wrong position under the old name in an existing
tracking window - for example, I'm showing 'ISS' as being nortwhest of
Australia right now, and 'ISS (ZARYA)' is over Canada (which agrees
with JTrack).

I'll still be using Traksat 4.03 and the JTrack page to cross-check
things until all this shakes out.

Standard disclaimers apply.  YMMV.  Not valid with another special
offer.  Close cover before striking match.
