【摘要】：針對現(xiàn)有慣導(dǎo)系統(tǒng)高緯航向、速度誤差增大和導(dǎo)航參數(shù)不能滿足大圓航行需求的問題,研究一種基于極球面投影的慣導(dǎo)高緯導(dǎo)航方法.首先借鑒極球面投影網(wǎng)格導(dǎo)航的思想構(gòu)建橢球面網(wǎng)格航向基準(zhǔn)模型,然后利用慣導(dǎo)系統(tǒng)原有解算信息,以實(shí)現(xiàn)網(wǎng)格航向和網(wǎng)格速度解算,最后在分析高緯導(dǎo)航方法誤差抑制機(jī)理的基礎(chǔ)上對高緯導(dǎo)航參數(shù)性能進(jìn)行評估.理論分析和仿真結(jié)果表明:該方法可以有效提高慣導(dǎo)系統(tǒng)高緯導(dǎo)航性能,能夠滿足載體高緯航行需求.
[Abstract]:In view of the problems of high latitude heading of the existing inertial navigation system, the increase of velocity error and the inability of navigation parameters to meet the requirements of large circle navigation, A method of inertial navigation with high latitude based on polar spherical projection is studied. Firstly, the ellipsoidal grid heading reference model is constructed by using the idea of polar spherical projection grid navigation, and then the original calculation information of inertial navigation system is used. In order to realize grid heading and grid velocity solution, Finally, based on the analysis of error suppression mechanism of high latitude navigation method, the performance of high latitude navigation parameters is evaluated. The theoretical analysis and simulation results show that this method can effectively improve the high latitude navigation performance of inertial navigation system. It can meet the needs of carrier navigation in high latitude.
