According to the error of Inertial navigation system ( INS ) is increasing in all time steps and importance of the knowing the precise position of the vehicles so it is necessary that the error model is identified precisely .

This paper described the theoretical and analytical model of INS’s position error according to sources of errors then the result is compared with the numerical simulation of INS system in Autonomous Underwater vehicles ( AUV) so the validation of the result is evaluated .

The theoretical error model use the operation error in time transition mode then it is trivial that it cannot track the result of INS system precisely so with extension the method the result is improved in accepted range.
