为解决舰载惯性导航系统对准时间长的问题，利用分段线性系统理论（PWCS）方法分析了系统的可观测性，并提出了适用于双轴旋转式激光陀螺惯导的多位置对准方案，仿真结果表明该方法在4h内可完成所有陀螺和加速计零位误差的估计，可实现舰栽惯导4h高精度快速对准，具有较好的工程应用价值。

To solve the problem about long time alignment of ship initial navigation system, the PWCS is used to analyse observation of system. And then a method with several positions alignment is brought forward, which is suitable for two-axis rotating inertial navigation system. The simulation results show that the method can estimate drift of all gyroscopes and celelerometers in 4 hours. The method can achieve the high precious and fast alignment, and it is also useful in practice.
