USAT88.BAS/EXE - A Real Time Satellite Tracking Program
"It ain't pretty but it works!"
------------------------------------------------------------------------
This is a updated version of a program of similar name. The BASIC
source code (in ASCII format) gives full credit to the original authors.
I take absolutely NO CREDIT for anything other than making this wonderfull
piece of public domain software available and the mods to update the program
for '88 and '89.
The changes -
-------------
The only changes made were to update the siderial time tables in two places
in the BASIC code and to change the ELEMENTS.DAT file to KEPELER.DAT. This
was done because of a change in the data format to permit reference orbits
greater than 32767. YOU CAN'T USE THE ELEMENTS.DAT FILE BY RENAMING IT.
Simply start the program, select the option to ADD/CHANGE/DELETE a satellite,
enter all of the data for your favorite birds and let 'er rip! A sample file
is included and can be used as a starting point. The data used was valid at
the end of December 1987.

------------------------
A small bug was introduced in the process. The compiled program no longer
states the GROUND SATAION name or location in the real time tracking display
or on the printout. It DOES know exactly where you've told it you are so the
program still works properly otherwise. If anyone can track this bug down and
apply some "RAID" I'll be forever gratefull.
I think it's a string problem with my version of MICROSOFT QUICKBASIC (v2.0)
since running the BASIC program works with everything showing as it should.
Just remove or REMark the two lines for the BASIC version to run properly.
The code included is the exact same code used to compile the program after a
test period running as a straight BASIC program.
Getting the new elements to update the program.
-----------------------------------------------
New KEPELER elements can be had by calling (315) 697-3996. That's the number
for the RANDOM ACCESS BBS. It's a dial-up system available 24 hours a day
at either 300 or 1200 baud. Look in the BULLETIN area in the HAM RADIO
bulletin section.
Kepeler elements are also available as ARRL bulletins on many Packet BBS's
around the country. AMSAT nets on 80 meters will also provide the needed
information.
