Book excerpt: An analytical study was made to assess the ability of a plot, simulated by permissible error performance, to control the entire lunar approach and descent with relatively simple guidance schemes. The control task consisted of applying retrothrust during the hyperbolic approach to establish a lunar orbit. During this lunar coasting orbit, the lunar module was separated from the command and service module. A second deorbit thrust period was used on the lunar module to establish a coasting descent, and a final thrust period was used to put the vehicle into a reasonable landing situation. Throughout the maneuver the pilot was permitted to make reasonable errors, selected in a random manner, in the thrust time and attitude control. The control schemes consisted of maintaining a constant vehicle attitude with respect to the line of sight to the lunar horizon for the first and second thrust periods, and a constant angle with respect to the line of sight to the orbiting command and service module for the third thrust period.--P. [i].
