Aerospace Instrument-Making Annotation << Back COMPONENTS OF MODEL OF DRIFT DYNAMICALLY TUNED GYRO V.P. Podchezertsev, Tang Xingyuan, Qin Zihao The paper represents analysis of major factors defining accuracy of characteristics dynamically tuned gyro (DTG) under operating conditions. The numerical estimation of influence of each of the considered factors on operational characteristics of a gyro is given. Classification of errors DTG to constructive and technological attributes, and also from the point of view of influence on the device of temperature, mechanical actions and magnetic fields is resulted. Considering, that now DTG are widely used in strapdown inertial navigation systems and systems of orientation where one of the basic operating modes is the mode of the rate sensor (RS) in paper estimations of a measuring error of this gyroscope in view of specificity of the specified mode are resulted. Keywords: dynamically tuned gyro (DTG), strapdown inertial navigation systems, elastic cardan-joint, errors of a gyroscope. zero signal of the pickoff, quadrature drift, gasodynamics moments, gyro time con-stant.
