This paper considers attitude control systems for an orbital spacecraft based on the principle of a gyrocompass. The primary focus is the development of the method of spatial programmed rotation of the spacecraft for systems continuously adjusted by local-vertical plotters (LVPs). The main algorithm and block diagram of the gyrocompass, named the “spatial 3D gyrocompass,” have been obtained. The possibility of programmed attitude control of a spacecraft with a disabled gyrocompass correction loop without restrictions on the angles of programmed rotations is shown. A particular case, which is in demand in practice, of a plane rotation of the spacecraft along the course to an arbitrary programmed angle, is considered. A calibration method by means of autocompensation of deterministic errors of LVPs and gyroscopic angular velocity sensors is proposed, which significantly increases the attitude accuracy.
