Preliminary Recognition and Modification for D6 Program

On the basis of understanding of the D6 program, thispaper presents some objective comments and makes some improvements onthe D6 program. The emphasis is put on the detailed explanation and deri-vation of the coordinate system and mathematical models, and a method ispresented to get the motion elements of a projectle of six degrees of free-dom in the earth coordinate system. It is of practical value in both corr-ect understanding and rapid applying of the program.
