Algorithm of Specification of Motion Parameters of Spacecraft by Reduced Volume of Measurement Information

摘要

A problem of specification of motion parameters of a spacecraft (SC) for remote Earth probing by results of measurements of navigation parameters is considered. We analyze specific features of ballistic-navigation support for a single-point control technology. It is demonstrated, that this technology does not satisfy requirements for accuracy and efficiency of obtaining necessary ballistic-navigation information. We suggest enhancing accuracy and efficiency of calculation of ballistic information by minimization of the goal function of specification of motion parameters of an SC by search methods. Results of analysis of the developed algorithm of specification of motion parameters of an SC on the basis of the simplex optimization method are presented.
