The ensuing study of the THREE DIMENSIONAL ANALYSIS OF SATELLITE ORBITS BY MEANS OF ANALOG SIMULATION has a three-fold purpose: A. Due to the complexity of analyzing large digital programs in trajectory analysis, it would be advantageous to have an analog simulation which would show a continuous visual output of position and velocity of a vehicle traveling in a near-earth orbit. B. The knowledge gained from Part A should then aid in the development of an analog model which could be used to search for the initial conditions (of position and velocity) to start the digital matched-conic program if the target position and the time of arrival are known. C. The third aspect of the project is to develop an analog simulation based on the theory of perturbation. This model should incorporate the technique learned of dis playing the nominal and perturbed values of a (actual Apollo flight re-entry) trajectory three dimensionally.
