摘　　要：为了提高捷联惯性测量装置(SIMU)的测量精度,在使用前必须对其进行标定,以确定SIMU的参数及性能指标。为此研究了一种SIMU的全温度标定方法,利用专用的测试设备对SIMU进行全温度标定试验。给出了SIMU的静态模型方程,详细介绍了模型方程中各参数的标定方法及具体的误差补偿计算方法,最后给出了SIMU综合性能指标的计算。经过多发SIMU的标定实验,结果表明:该标定方法有效地提高了SIMU的实际实用精度。The Strap-down Inertial Measurement Unit（SIMU）must be calibrated before putting into use to improve its measurement precision and obtain its parameters and performance specifications. A method for calibrating SIMU at all environmental temperature was studied, a special test equipment was used for the calibrating test at all environmental temperature. Static model equations of SIMU were provided, the od of all parameters in the model equations and the calculating calibrating methmethod about error compensation were described in detail. The calculation of the SIMU＇s synthesis performance specifications was also presented. Lots of SIMUs have been calibrated. The experiment results showed that the applied precision of SIMU was improved effectively by this calibrating method.
