A trajectory computation program is described for determining vehicle performance throughout the entire flight regime of speed and altitude in the atmosphere and gravity field of a nonspherical rotating planet. The program is formulated for seven options of varying refinement from the six-degree-of- freedom problem to the two-degree point mass problem. A reverse option for the aerodynamic analysis of flight test data, a punched card output, and a semiautomatic computational tie to an interplanetary trajectory computer program are included. The program is specifically oriented for computation on the IBM 7090/7094 digital computer using the FAP/FORTRAN2 machine language.
