Development Of Calibration Device For Inertial Navigation Turntable

Inertial navigation turntable is a large category of inertial technology testing equipment.Inertial navigation turntable is a special test equipment developed for the test requirements of inertial components such as gyro,accelerometer and inertial navigation.It provides the position,speed and other benchmarks for the evaluation The accuracy of the inertial navigation turntable directly affects the reliability of the inertial navigation system and inertial devices.The inertial navigation turntable develops rapidly,however,the performance index of the inertial navigation Turntable lacks of high-precision calibration equipment to calibrate it.There are main performance test methods,but lack of relevant calibration equipmentIn the paper,firstly,through the theoretical research on the angle position measurement method,the angle rate measurement method and uncertainty of the inertial navigation table,and integrating the measurement characteristics and technical requirements of the inertial navigation table,it is verified that the development of The inertial navigation table calibration device in this paper is technically feasible.Developed in this paper,inertial turntable calibration device build A ngle rate and dynamic characteristic measuring system,angular position measuring system,the three systems,form and position error measuring system design,mainly through Rate and dynamic characteristic measuring system is developed according to the actual and precision measurement under the condition of existing work requires,auxiliary tooling design,implement different type turntable to carry out the on-site calibration work in their own units.Finally,by analyzing the test data of the inertial navigation turntable calibration device and evaluating the measurement uncertainty of the calibration device,the accuracy of the turntable calibration system is verified.The special calibration device for inertial navigation of the test and detection data of the inertial navigation system,and provide a strong measurement guarantee For our inertial navigation repair.
