THE MISSILE GUIDANCE LAW PROGRAM DEVELOPED A DIGITAL COM- PUTER PROGRAM (OPTGID) WHICH COMPUTES OPTIMAL MISSILE GUIDANCE LAWS. IT DETERMINES THE ANGLE-OF-ATTACK TIME- HISTORY TO SHAPE A VERTICAL PLANE TRAJECTORY TO OPTIMALLY MEET SPECIFIED PERFORMANCE INDICIES AND TERMINAL CONSTRAINTSTHREE GUIDANCE LAW OPTIONS ARE INCORPORATED INTO OPTGID: 1) MAXIMUM RANGE WITH AND WITHOUT A SPECIFIED TERMINAL VELOCITY, 2) 3-D (FIXED TERMINAL POSITION) AND 3) 4-D (FIXED TIME-OF-FLIGHT AS WELL AS FIXED FINAL POSITION). THE TERMINAL KINETIC ENERGY IS MAXIMIZED FOR THE 3-D AND 4-D GUIDANCE LAWS. THE GUIDANCE LAWS ARE FORMULATED AS TWO-POINT BOUNDARY VALUE PROBLEMS.
