摘要
Abstract
Inertial devices are the foundation of inertial systems,mainly including accelerometers and gyro-scopes.During the actual operation of an inertial navigation system,the inertial components will experi-ence changes in indicators such as zero bias and scale factor with changes in ambient temperature,which ultimately affect the initial alignment and navigation accuracy of the inertial navigation system.Among them,gyroscopes generally adopt temperature control measures to ensure adaptability to the full tempera-ture range,while accelerometers generally adopt temperature compensation technology for miniaturization and low power consumption considerations.To eliminate the influence of environmental temperature on the accuracy of the accelerometer,it is necessary to calibrate the zero bias and scale factor of the acceler-ometer within the full temperature working range of-25℃to 45℃,Automatic temperature calibration and compensation using a dual-axis turntable temperature box,find the mathematical laws related to tem-perature,establish a compensation mathematical model,and use this model for temperature compensa-tion.After temperature compensation,the output accuracy of the accelerometer can be improved by an order of magnitude,and the compensation effect is significant.关键词
