The thesis analyse the error and the feasibility of the system . because the precision of position and direction is related with the precision of the heading and the distance , the thesis discuss the method of obtaining the distance using milemeter , water milemeten engine ' s rotate speed and accelerometer , and the method of obtaining the heading using the combination of the gyrocompass and the digital compass . then the thesis introduce the details of the system realization , include the hardware and the software 由于航位推算的精度与航程和航向的精度直接相关，因此，论文讨论了用里程计、水速表、引擎转速或加速度计等获取里程的方法，用航向保持器和数字磁罗盘组合的方法获取航向角的方法(初始寻北由数字磁罗盘来完成) ，这为采用数据融合方法提高航程和航向精度打下了基础。
