Abstract:

The purpose of the LORAN Grid Prediction Computer program is to transform geographic coordinates into a LORAN time difference TD. Utilizing available map data of terrain and lithology and applying an integral form of Maxwells equations, the propagation time of a low frequency pulse over irregular and inhomogeneous ground can be calculated. The method of data tape production and TD calculation is described with program listings. The technique has been successfully used by several U.S. Government agencies. Author
