METHOD OF ORIENTING SPACECRAFT USING GIMBALLESS ORBITAL GYROCOMPASS AND SYSTEM THEREFOR Russian patent published in 2016 - IPC B64G1/24 

FIELD: astronautics.

SUBSTANCE: invention can be used for orientation of spacecraft. Spacecraft orientation system using gimballess orbital gyrocompass (BOGK) comprises a device for orientation on ground (POZ), a unit of gyroscopic angular velocity meters (BIUS), program control module (PMU), eleven adders, three amplification modules (MU), five integrators, four module interference compensation channels (MKVK), cosine converter (KP), sine converter (SP), two switches. In steady-state orientation is measured signal difference of POZ and output signals BOGK in channels of roll and pitch, to correct readings and BIUS in channels of roll and heading, pitch, course turn by 90 degrees with substitution of bank gyrocompassing channel with pitch gyrocompassing channel, continued oriented orbital flight is in signal correction in pitch channel signal error autocompensation POS pitch BOGK correction signal is calculated in pitch channel, is waited for completion of transition processes in circuit of orientation, stored accumulated signal value autocompensation in pitch channel and is switched off its accumulation is rotated back spacecraft course, reverse substitution of roll and pitch channels BOGK, BOGK correction channel is added to pitch signal value autocompensation as correction for deterministic BOGK orientation error in pitch channel, calculating correction signal in pitch channel, introduced into difference signal for channels of roll and heading signal autocompensation deterministic errors POS bank, new BOGK correction signal is calculated in channels of roll and heading.

EFFECT: compensation for errors in spacecraft orientation relative to orbital coordinate system.
