The generalized forward iterator
Wayne E. Moore · NASA Technical Reports Server (NASA) · 1966
A computer progrm has been written which constructs optimized Apollo missions.It is ilighly versatile; it will produce a scan of several related missions or an accurate trajectory of reference quality.Speed and accuracy are purely dependent on the mathematical model chosen for each particular case.This model could consist of an array of two-body approximations, or of a precise numerical integration of the equations of motion going by the Encke method when applicable.The program is extremely flexible with regard to the mission that can be constructed, and the extent to which it can be optimized.This note indicates how the input describes the mission and the method of computation to the computer.It also presents the various mathematical trajectory models that are available.
