Description: 随着GPS性能的不断完善，应用越来越广泛，但GPS系统易受到外界环境影响，而传统的惯导系统也具有误差随时间积累的缺陷，因此GPS/INS组合方式因其互补性强已经成为实现导航的重要方式。这种组合方式能够确保在采用较廉价的惯性设备的情况下，也能获得较好的导航效果。-With the constant improvement of the GPS performance, more and more widely, but the GPS system vulnerable to external environmental impact, and the defects of traditional inertial navigation system error accumulated over time, so the GPS/INS Integrated because of its strong complementary already become an important way of navigation. This combination can be ensured in the case of using cheaper inertia device, it can get better navigation results. Platform: |

Description: 光纤陀螺是基于效应工作的角速率传感器，具有全固态、体积小、
质量轻、动态范围宽、启动快、成本低、易集成等突出特点，在军事和民用领
域备受世界各国关注，获得了广泛应用。然而，受元器件性能、寄生效应和周
围环境的影响，光纤陀螺的输出易产生漂移，影响惯性导航系统的精度。因此，
抑制光纤陀螺漂移误差，提高其测量精度具有重要意义。(Fiber optic gyroscope(FOG) is a kind of angular rate sensor based on Sagnac
erect with solid state, small size, light weight, wide dynamic range, fast starting,
low cost, high reliability and so on. Many countries pay much attention to FOG for
the military and civilian purposes. FOG is widely used in the world because of its
outstanding features. However, FOG is easily affected by the performance of its
components, parasitic effects and the surroundings. This leads to the FOG output
drift and deteriorates the precision of the inertial navigation system. Therefore, it is
significantly important to suppress the FOG drift error to improve the FOG
measurement accuracy.) Platform: |
