METHOD OF CALIBRATION OF SENSITIVE ELEMENTS OF STRAPDOWN INERTIAL NAVIGATION SYSTEM AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: physics. ^ SUBSTANCE: invention is related to the field of instrument making and may be used in creation of strapdown inertial control systems (SICS) for calibration of sensitive elements (SE). In biaxial Cardan suspension (CS) instrument platform is installed, on which in special manner three accelerometers and three angular speed detectors (ASD) are installed. On CS axes angle detectors (AD) are installed and motors for setting of accelerometers IO and ASDs into working positions for calibration. At that in device for method implementation into biaxial CS instrument platform (IP) is installed, on which three accelerometers and three ASDs are installed. On CS axes ADs and motors are installed, for rotation of IP in relation to the object. ^ EFFECT: increase of calibration accuracy. ^ 2 cl, 2 dwg
