Description: This report presents two great circle navigation algorithms, a closest point of approach      algorithm and intercept algorithm. It also presents an implementation program for the      algorithms that is written in the BASIC language for an IBM PC. Instead of using classical      spherical geometry or the general spherical triangle, these algorithms incorporate      rectangular coordinates and vectors on the surface of the spherical. The intent of the      report is to provide algorithms for spherical earth models that can be used for situations in      which flat earth models are not appropriate, but that do not require the sophistication of      rotating earth models.
