Title ON One Possibility of Orientation of a Near-Earth Spacecraft in the Earth's Magnetic Field
Author(s) I.N. Abezyaev (JSC Military and Industrial Corporation "NPO Mashinostroyenia," Reutov, Moscow region, 143966 Russia, iabezyaev@yandex.ru)
Abstract An active attitude control system (ACS) of an orbiting near-Earth spacecraft (SC), containing an on-board computer, a block of gyroscopic angular velocity sensors (BGAVS) and executive bodies (flywheels, gyrodines, jet engines), is considered. It is proposed to use magnetometers (MGM) installed along the coupled axes of the spacecraft as an external information sensor. We call such a system a magnetic-gyroscopic attitude control system (MGACS). It is shown that the use of MGM as an attitude sensor does not violate the functionality of the orientation of modern spacecraft and allows you to perform such flight modes as attitude restoration (AR) and program orientation of the spacecraft relative to the orbital coordinate system (OCS). The principle of construction of MGACS is stated, working algorithms are given, an estimate of orientation accuracy is given, simulation results are presented.
