| 摘 要： | 扰动基础上的初始对准是车载激光陀螺惯导系统(L INS)的难点技术之一。针对 L INS在车辆发动机不关闭和有少量人员走动的情况 ,进行了大量实验研究。通过分析L INS惯性元件的信号特征 ,改进 Kalm an滤波对准技术。对获得的观测信号进行预处理 ,降低干扰影响 ;并改进Kalman算法 ,使之具有更好的稳定性。实验结果表明 ,该算法对于提高扰动基础上的对准精度是有效的

| Abstract: | The initial alignment of laser gyroscope inertial navigation system (LINS) for land vehicles is difficult when disturbance are present, for example when the motor is running on or people are walking in the vehicle. The Kalman filter alignment technique was developed for signal analyses of the LINS inertial instruments. The observation signals were pre processed to reduce the interference, then the Kalman filter algorithm was improved to increase the stability. The experimental results show that this technique effectively increases the alignment accuracy with disturbances. |
