| 摘 要： | 针对静基座捷联惯导的初始对准和标定，提出了一种基于虚拟噪声的现场最优标定方法，即两步估计法。同多位置对准方法相比，其特点是结构简单、省时、易于实现，既能保持一定的姿态精度，又能大大降低导航和定位误差，特别适用于短时间、低中精度导航系统。 |

| Abstract: | In view of the initial alignment and calibration for strapdown inertial navigation systems on stationary base, this paper presents an on-field optimal calibration method based on fictitious noises, i.e. two-step estimation. Compared with the multiposition alignment method, it is characterized by simple structure, less time consumption and easy to implement. This two-step estimation could retain fairly high attitude accuracy, and reduce the navigation and positioning errors significantly, especially suited for shout-time, low and middle precision navigation systems. |
| Keywords: | strapdown inertial navigation initial alignment calibration optimal estimation |
