| Abstract: | For the truth that the error angle of course in the static error model of SINS is usually unobserved. A reconstructed static error model was brought forward for this problem. This model was gotten by decomposing the observability framework of initial model and making status transform. Theroy analysis indicated that the error angle of course in the reconstructed model is observable in some degree. It indicated that the result that got by the KF alignment which used the reconstructed model was better than that got by parameter identification alignment by using the date generated by certain type laser SINS. This reconstructed model was usefull and practical. |
