Повышение точности ориентации космических аппаратов мониторинга Земли в полёте

Повышение точности ориентации космических аппаратов мониторинга Земли в полёте

Abstract

The paper presents the problems of assessing the relative position of angular accelerometer sensitivity axes and astromeasuring basis of the attitude control system as part of flight calibration of a platform-independent inertial system. The inaccuracy of the angular accelerometer is defined and taken into account. An algorithm of in-flight geometrical and parametric calibration of the meter is suggested.

Рассмотрены вопросы реализации полётной калибровки бесплатформенной инерциальной системы ориентации в части оценки взаимного положения осей измерителя угловой скорости и астроизмерительного базиса системы управления ориентацией, а также вопросы определения и учёта погрешностей измерителя угловой скорости. Предложен алгоритм полётной геометрической и параметрической калибровки этого измерителя.
