【摘要】：采用旋轉(zhuǎn)調(diào)制技術(shù),研究了以動(dòng)調(diào)陀螺為角速率傳感器的全姿態(tài)尋北儀。為了控制有色噪聲對(duì)動(dòng)態(tài)尋北的影響,利用觀測殘差建立了有色噪聲的AR模型,對(duì)有色噪聲進(jìn)行了擬合與預(yù)報(bào),并利用改正后的觀測信息、基于抗差估計(jì)原理構(gòu)造了高崩潰污染率的初值輔以IGGⅢ方案迭代解算的混合算法。計(jì)算結(jié)果表明:采用AR模型對(duì)有色噪聲進(jìn)行擬合與預(yù)報(bào),能夠有效控制有色噪聲的影響,并提高動(dòng)態(tài)尋北的精度和可靠性。
[Abstract]:In order to control the influence of colored noise on dynamic north finding, an AR model of colored noise is established by using the residual of observation. The colored noise is fitted and predicted, and the corrected observation information is used. Based on robust estimation principle, a mixed algorithm of initial value of high collapse pollution rate and iterative solution of IGG 鈪，
