| 摘 要： | 热效应是影响捷联惯性导航系统精度的重要因素。通过对加速度计组合温度误差来源的分析，结合大量温度试验，着重分析了温度对加速度计组合安装误差角的影响。试验表明，在对加速度计刻度因子与零偏进行补偿的基础上，加入安装误差角的温度补偿之后，加速度计组合测量精度得到较大的提高，平均提高了近3倍。

| Abstract: | To reduce the thermal influence on the performance of SINS inertial sensors, a thermal model for engineering applications is presented based on temperature tests and corresponding characteristic analysis on accelerometers, especially on the misalignment angle of accelerometers. After compensation for the accelerom -eters, the accuracy of accelerometers is greatly improved. Test results indicate that, due to the compensation of scale factor, bias and misalignment angle, the accuracy of accelerometers is improved about 3 times. |
