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.
