I have now placed some satellite tracking programs on World:
- stsplus.zip
- stsorbit.zip
- traksat {trak300a.zip & trak300b.zip} (latest version of traksat)
They are available via anonymous FTP via
ftp ftp.std.com:/pub/hamradio/pc/satellite
If you have any problems, questions, or comments, please e-mail them to me.
I tried very hard to search for stsplus through many archie searches, and
only found one site which carried it. I hope that by making it available
on World it will be easier to obtain.
73,
Scott, WY1Z
