【摘要】：為了抑制慣性導(dǎo)航系統(tǒng)的誤差累積效應(yīng),提出了用激光多普勒測速儀與捷聯(lián)慣導(dǎo)進(jìn)行組合�；诜止庠倮玫乃枷朐O(shè)計了新型光路結(jié)構(gòu)的激光多普勒測速儀,并詳細(xì)討論了激光測速儀與捷聯(lián)慣導(dǎo)組合進(jìn)行航跡推算的過程。理論分析和實驗結(jié)果表明,分光再利用型激光多普勒測速儀測量精度高、數(shù)據(jù)有效性及穩(wěn)定性好,將其用于車載慣性導(dǎo)航系統(tǒng)大大提高了導(dǎo)航精度,位置誤差由純捷聯(lián)慣導(dǎo)2 h1166 m提高到組合系統(tǒng)2 h 20 m。
[Abstract]:In order to suppress the error accumulation effect of inertial navigation system, the laser Doppler velocimeter and strapdown inertial navigation system are combined. A new type of laser Doppler velocimeter with optical path structure is designed based on the idea of reusing the light splitter. The process of track calculation combined with laser velocimeter and strapdown inertial navigation is discussed in detail. The theoretical analysis and experimental results show that the laser Doppler velocimeter with split-light reutilization has high measurement accuracy, good data validity and stability. The accuracy of navigation is greatly improved when it is used in vehicle inertial navigation system, and the position error is increased from 2h1166m to 2h20m for pure strapdown inertial navigation system.
