C# NORAD SGP4/SDP4 Implementation Developed by Michael F. Henry Copyright © 2003-2011 Michael F. Henry. All rights reserved. Permission to use for non-commercial purposes only. All other uses contact author at mfh@zeptomoby.com The files in this package provide a C# implementation of the SGP4 and SDP4 algorithms described in the December, 1980 NORAD document "Space Track Report No. 3". These two orbital models, one for "near-earth" objects and one for "deep space" objects, are widely used in satellite tracking software and can produce very accurate results when used with current NORAD two-line element data. The files are contained in two directories: OrbitTools and OrbitToolsDemo. The files in the OrbitTools directory are compiled to make the OrbitTools assemblies, which contain the NORAD SGP4/SDP4 implementations and miscellaneous supporting classes. See the "readme.txt" file in the OrbitTools directory for more information. The files in the OrbitToolsDemo directory are compiled to make a sample executable program. The program demonstrates how to use the OrbitTools assemblies to calculate the ECI position of a satellite, as well as determine the look angle from a location on the Earth to the satellite. See the "readme.txt" file in the OrbitToolsDemo directory for more information. The project files were compiled using Microsoft Visual Studio 2010. For excellent information on the underlying physics of orbits, visible satellite observations, current NORAD TLE data, and other related material, see http://www.celestrak.com which is maintained by Dr. T.S.
