- The file master.dir in this directory is a complete listing of the space-
- related programs, data, and documentation available for download from the
- Celestial BBS, 205/*409-9280*, which operates at 300/1200/2400/4800/9600 bps,
- 24 hours/day. Due to the extensive nature of these files, it is impossible
- for me to maintain two sources, with the exception of the weekly postings
- of two-line element sets (tle.*) and these key programs:
-
- * spacetrk.zip (LaTeX documentation and FORTRAN source code for the NORAD
- orbital models needed for using the two-line element sets),
- * sat-db13.zip (a complete database of all payloads launched into orbit),
- * sgp4-pl2.zip (a library of Turbo Pascal units to implement SGP4/SDP4),
- * trakstr2.zip (an implementation of sgp4-pl2 to output satellite ECI
- position, subpoint, look angles, and right ascension/declination),
- * passupdt.zip (a package for quickly and easily updating two-line element
- sets), and
- * unzip (a Sun executable for unzipping these programs).
-
- More information on the first five files is available in the file master.dir.
-
- There is no access charge for using the Celestial BBS and the file master.dir
- should serve to give you a pretty good idea of the value of the material
- available there.
