| Abstract: | This paper holds that the key to im prove the hitting rate ofair-to-air m issiles is to de- crease the error ofinitialalignm entofthe inertialnavigation system . Therefore, considering thatthe alignm entshould becom pleted w ithin a specified shorttim e, thispaperpresentsthe theory oftransfer alignm ent and the com puting w ay of accuracy in an air-to-air m issile, w here the platform inertial navigation system , orm asterINS, isadopted on aircraft, and thestrap-dow n inertialnavigation sys- tem , or slave INS, isused on m issile. Item phasizes the idea oftransfer alignm ent, thatis, calibra- tion oftheslave INSisbased on the m asterplatform , and adoptsa reasoning m easure to dealw ith the installing-error-angle. And it is proved by sim ulation that the transfer alignm ent can be quickly achieved. |
