Abstract: According to the limit of Global Position System(GPS) signal indoor for dynamic positioning ship model, a high accurate indoor location scheme based on ultrasonic is presented. Weighted least squares method is adopted to establish the system location algorithm model, the solving processes of the equation are given, and the calculation results are analyzed. Experimental results show that the theory data derived from the proposed algorithm fit well with the experimental data, which provides theoretical basis for the development and application of dynamic positioning ship model.
