| 摘要: |
| 在分析法国MARINS光纤惯导方案及温度试验的基础上，论证提出了一种带温控高精度光纤陀螺捷联惯导设计方法，并在温箱稳定环境下进行了试验验证。试验表明，在温箱温控精度为0.1℃的条件下，惯导系统精度可以达到1nmile/10d；若实装，温控精度将优于0.02℃，光纤惯导精度还可进一步提高。 |

| Abstract: |
| Based on the deep analysis of the project and test of MARINS in France, a designing method of an accurate FOG-SINS with temperature control is introduced and experimentally validated at a constant temperature in the environmental chamber. The result shows that the 10-day navigation precision of FOG-SINS can reach 1 nmile when the temperature control precision of the environment chamber is 0.1℃ and can be further improved if the temperature control precision reaches 0.02℃ through precise temperature control methods. |
