SAT-AIM 1.2 (c) September 12, 1999 - Giuseppe Lancia - Rome, Italy

USAGE: 

(a) sat-aim  
(b) sat-aim infile
(c) sat-aim Town latitude longitude infile outfile 
(d) sat-aim Town latitude longitude infile outfile j
(e) sat-aim Town latitude longitude infile outfile c


MEANING:

(a) calls this help file.

(b) Test mode, to see if the program works. Town name will be set to Rome and
therefore latitude and longitude will be set to 41.9 and 12.48, respectively.
Infile must be a text file, have a look at "italy" to see its format.
Outfile will be a TAB delimited text file, named Rome.

(c) Same as (b), but here you have to supply complete data, i.e town name,
latitude, longitude, infile and outfile names. Outfile will be TAB delimited.

(d) Same as (c), but "j" option will provide a justified output, suitable for
direct insertion into a word processor.

(e) Same as (c), but "c" option will provide a comma delimited output, that
one can use to import the output file to a spreadsheet program.


WHAT IT DOES:

This program calculates aiming data (azimuth/elevation) for a given list of 
DTH satellites above the horizon, to use for dish installation. In order to 
do this you need to have a text file containing a list of those satellites,
in the form:

+28.8 Astra2
+19.2 Astra1
+13 Eutelsat Hot Bird
-1 Intelsat 707 ...and so on.

Please note that geostationery satellites east of Greenwich will be located
from +0 to +180, while west ones will be in the range +0 to -180. Same rule
applies to the site latitude and longitude, this means the program should work
for any given site on earth, either northern or southern hemisphere. As an
example you will find an enclosed file, called ITALY, with a ready made list,
known to work for Italy (files covering America and Asia are supplied too).
If you do not insert your Site Name, latitude and longitude, in the form +/-
ww.xx and +/-yy.zz, the program assumes you are in Rome (41.9 12.48) and your 
outfile is set to "ROME". Aiming data will then conform to that assumption.
Consider it as test mode to see if the program runs OK on your computer, and
it should, since it's been compiled with PCC, for 8086/8088 processors and
small memory model. A special version, called DOSAIM_A.ZIP also works on a
Toshiba T1100 Plus with only two 3.5" 720kBytes floppy drives! I did not test
it on FAT32, because I don't like it and will never use it. When I decided it
was time to switch to a more serious system, I chose Linux, not M$oft! :-)

This program is freeware and has been written as an exercise to learn C 
language but, to my knowledge, this is the best program ever written to
accomplish this relatively simple task. You can copy it, distribute it but
not sell it, and you are not entitled to change this help file in any way.

The author does not take any reponsibility for any damage it could cause
to your system, even if it has obviously been tested, so use it at your own
risk!
