| 摘 要： | 激光陀螺是捷联惯导系统的理想元件,并广泛应用于航空、航天、航海以及地面定位定向等方面;但是,激光陀螺对温度十分敏感,温度的变化会造成激光陀螺零偏的变化,最终影响捷联系统的初始对准和导航精度;所以当要求激光陀螺工作在高精度的场合时,必须采取必要的温度误差补偿措施;通过对激光陀螺进行大量的温度试验,分析了温度及温变速率对激光陀螺零偏的影响规律,提出了激光陀螺温度补偿模型;经试验验证,此模型能在一定程度上改善温度对激光陀螺精度的影响,为进一步提高激光陀螺的精度打下基础。

| Abstract: | Laser gyro strapdown inertial navigation system is the ideal components,and is widely used in aviation,aerospace,marine and ground positioning orientation and so on.However,the laser gyro is very sensitive to temperature,the temperature will cause changes in laser gyro,the ultimate impact of SINS initial alignment and navigation accuracy.So when the work required in high precision laser gyro occasion,we must take the necessary temperature error compensation.Based on the laser gyro,a large number of temperat... |
