GIMBALLESS ATTITUDE CONTROL SYSTEM Russian patent published in 2000 - IPC

FIELD: gyroscopic attitude control and navigational systems. SUBSTANCE: proposed system includes angular-rate sensor unit and angular orientation determination unit, circuits "n" (n is no less than 1) of three-channel integrators and integrator synchronous restart unit connected in series. Output signals from angular-rate sensor are furnished to inputs of first integrator; these signals show present magnitudes of first integrators from angular rate components being measured; output signals of angular-rate sensor and of all integrators are furnished to input of orientation unit where parameters of orientation are calculated. All integrators have additional input for receiving signal from restart unit in order to ensure synchronous restart at zeroing all integrators at cycle time equal to scanning cycle time of angular- rate sensor. Required accuracy of generation of parameters of angular orientation under conditions of radio-frequency noise and angular vibrations of base is ensured due to use of output signals of integrators which are just increments of multiple integrals of angular-rate components being measured without use of additional smoothing of output signals of angular-rate sensor unit. EFFECT: enhanced efficiency and reliability. 2 dwg
