ViewSat Revision history:
1.03B 3/27/92
Added multiple satellite selection.
Added select satellite(s) by NORAD number.
Changed "Length of simulation:(days)" to "Length of run:(dd/hh:mm)" to
make it easier to do a limited time run (say 1 hour).
Added new "Minimum satellite range" to filter out visible passes which
are too far away to be seen well (they are to dim).
1.04B 4/08/92
Fixed "Output all data" so ALL data is actually output.
Fixed bug when changing "Time from UTC" had no effect until the program
was restarted.
Added a "Special thanks" note to Paul Traufler.
1.05 4/26/92
Revised document file to include my new membership in the Assosiation of
Shareware Professionals.
1.06 11/09/92
Fixed a bug related to entering a full drive:path\filename in the "element
data file" menu item or if the previously saved path does not exist.
1.07 11/19/92
Reduced minimum memory required to run from 578,000 to 470,000 bytes.
Added satellite illumination phase angle to output.
Increased maximum number of satellites in an element data file from 800
to 1000 satellites.
Increased valid range for "Maximum sun elevation" to +/- 90 degrees.
Increased valid range for "Minimum satellite elevation" to +/- 90 degrees.
Replaced "Minimum satellite range" with "Maximum magnitude" and removed
"Visible passes only" flag. Brightness being the key to "seeing" a
satellite. Also removed "Output all data" flag as this is the same as
setting Maximum magnitude to 100, Minimum Satellite elevation to -90,
and Maximum sun elevation to 90.
Added an entry for "Minimum mean motion". This allows the user to set the
limit to filter out geo-sync (or other) satellites to improve the
prediction speed for a large number of satellite elements. This was
hard coded at 10 in previous versions.
Fixed bug when changing location (lat, lon, ele) had no effect until the
program was restarted.
Improved error handling for disk I/O when writing prediction output.
1.08 12/08/92
Improved speed (especially for multiple day predictions).
Fixed problems with missing some passes.
Added a flag to select whether skipped satellite's NORAD number and Name
will be printed to the output file.
