objekti (kosmoseaparaadi) orienteerimine inertsiaalse taustsüsteemi või muu objekti suhtes
controlling the orientation of an object with respect to an inertial frame of reference or another entity (the celestial sphere, certain fields, nearby objects, etc.)
Kosmoseaparaadi orienteerimiseks on vaja järgmisi elemente:- andureid, et mõõta kosmoseaparaadi orientatsiooni;- aktuaatoreid, et rakendada pöördemomenti kosmoseaparaadi orientatsiooni muutmiseks;- algoritme, et kontrollida mõõtmiste põhjal aktuaatoreid, saavutamaks soovitud orientatsioon.
Disturbance torques, such as atmospheric drag torque and gravity gradient torque, have always been an issue in attitude control for satellites in low Earth orbit. There is a long history of research on attitude control using disturbance torque, and an aerodynamic stabilization system has been installed in the technology demonstration satellites Cosmos-149 (1967) and Cosmos-320 (1970).
