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.
