norad: Translation of NORAD's SPACETRACK SGP*/SDP* routines
from FORTRAN to C:
I have translated the SGP*/SDP* routines in NORAD's Spacetrack Report #3 from FORTRAN to C, to make it easier to incorporate them in satellite tracking software. This package only has the translated routines plus a simple C program to demonstrate their use.

sgp4sdp4: Satellite tracking routines based on norad and Dr.
Kelso's sgp4-plb26a library:
This is a very comprehensive satellite tracking code package based on the sgp4/sdp4 norad routines and my translation to C of Dr. Kelso's sgp4-plb26a PASCAL library. It can be used as the basis of a satellite tracking application complete with routines for the position of the Sun, the Moon, date and time conversions, illumination calculations and much more.
