METHOD OF EXPERIMENTAL COMPARATIVE PERFORMANCE EVALUATION BOARD NAVIGATION unmanned spacecraft in constructing the base coordinate system

摘要

Method experimental comparative evaluation of overall performance of the onboard navigation system automatically spacecraft (ASA), an orbiting and equipped with an autonomous navigation apparatus on the basis of the star sensor to build the base coordinate system (SBR) to a predetermined accuracy, wherein one of the criteria for evaluating the performance of the onboard system navigation is the build BSC, characterized in that two additional sets AKA stellar sensor so that they were rientirovany without overlapping fields of view to each other, and the efficiency of operation of the onboard navigation system is determined by Qi ACA complex criterion for each i-th portion of the orbit when constructing a capacitor bank to a predetermined accuracy by the formula: Qi = c1, i · Ti + c2, i · Ii + c3, i · Ei,! where Ti - time spent on the construction of SBR, s; ! Ii - resource consumption onboard computer, with; ! Ei - the amount of energy expended, W; ! i = 1, 2 ... N - section number construct SBR; ! c1, i, c2, i, c3, i - the weights determined by the formulas in each area of ​​construction of the Ivory Coast: ! ! ! and comparing the magnitude of the pilot complex criterion Qi with each other, the largest value corresponds to a lower efficiency of operation of the onboard navigation system AKA when constructing a capacitor bank.
