Autonomous orbit determination METHOD AND HOUSING ORIENTATION SPACECRAFT IN SPACE IN THE ABSENCE priori information

摘要

Method autonomous orbit determination and orientation of the body of the spacecraft (SC) in the space in the absence of a priori information, characterized in that each navigation session measured by a fixedly mounted at a body KA opto-electronic device coordinates of the stars and their magnitudes, as this information the on-board catalog stars geocentric coordinates determined on the basis of which the orientation axes calculated geocentric SC is formed over the entire measuring range hodographs axes SVs way recent analysis calculated approximate orbital parameters and orientation accepted for a priori (reference) information, and then restore the ability to operate the autonomous navigation and orientation system.
