The project generates a single executable, orbitToolsDemo.exe, which calculates ECI position and velocity information for satellites whose orbital elements were originally published in the 1980 NORAD document "Space Track Report No. 3". Also demonstrated is how to use the libraries to calculate the look angle from a location on earth to a satellite in orbit. The project files were compiled using Microsoft Visual Studio 2010. The correct program output appears below. Michael F.
