OPTIMAL RE-ENTRY GUIDANCE STUDY. PART I PROGRAM FORMULATION.
Abstract
A computer program was used to assess the relative performance of different measuring devices employed in a system subject to random errors. The system was composed of the simulation of a vehicle entering the atmosphere of the earth, a measuring scheme to gather data about the state variables, a data processor from which the best estimate of the state variable was obtained from the measurement data, and a control scheme which used the processed data in order to calculate the proper control force. A statistical evaluation of the performance of the system was obtained by using as a measure of the performance the terminal quadratic dispersion matrix which is the terminal mean square deviation of the state variables away from a nominal value. Various measurement schemes were compared by comparing the resulting terminal dispersion matrices of the system. The terminal dispersion matrix was calculated by two different methods in the program: by Monte Carlo analysis and by the application of linear theory.
