Abstract

In this study, it is surveyed and analyzed under the condition of developing GPS receiver that the present status of use and the precision of GPS receiver installed in naval vessels. Throughout interview and questionnaire with the workers in naval vessels, reliability and utilization of GPS receiver are verified. In conclusion, it is suggested that the development of GPS receiver system as well as navigation methods in naval vessels. The result of this study is as follows. Though the workers in naval vessels regard the accuracy of GPS receiver position as the fix by geographical navigation method. However, it is confirmed that its practical usage is when it is difficult to obtain the fix by geographical navigation method or R/D position or for ver verification. The suggested plans to develop the navigation methods from naval vessels standpoint are designing a parallel systems and introducing the GPS receiver system that functions well and is linked to the electronic navigation chart.
