Aerospace Instrument-Making Annotation << Back ITERATIVE PROCEDURE CALIBRATION SENSING ELEMENTS SINS I.H. Shaymardanov, A.A. Dzuev, Yu.G. Egorov, A.V. Nekrasov The problem of calibration of the strapdown inertial navigation systems (SINS) with the use of an accurate two-stage test bench is considered. Synthesis of the iterative procedure of calibration of sensing elements is carried out. Optimal SINS accelerometers calibration program is offered. Synthesized iterative calibration procedure in combination with the optimal calibration program provides: an increase in the accuracy and reliability of estimates of instrumental errors of the SINS sensing elements; a signifi cant reduction in the requirements for the accuracy of maintaining the temperature during the calibration; a signifi cant reduction in labor costs for the calibration of SINS sensors. The results of experimental studies confi rming the effectiveness of the developed iterative calibration procedure are presented. Key words: strapdown inertial navigation system, accelerometers, gyroscopes, calibration, iterative calibration procedure, iterative refi nement of the temperature model, optimal calibration program.
