Abstract：The strapdown attitude system has no latitude to be calculated ,causing heading's errors too large when the warship is cross‐latitudes sailing .Log's velocity with attitude and course of the strapdown attitude system is imported to cal‐culate latitude ,then mathematics model is established to process the initial alignment .Through sailing test ,course error's swing reduced much in 72h ,the possibility of the mathematics'model is verified that it can raise the accuracy of the system and has actual usage meaning .
