Abstract:	We installed two or more single-frequency RTK (Real Time Kinematic) systems on various work boats at sea and investigated any inconvenience caused in application of the systems in the actual working condition on board. A a result of the experiment, we found that the single-frequency RTK system showed good OI better performance than the dual-frquency RTK system. We conclude that the single-frequency RTK system can replace automatic-tracking work boat position control system using light wave so far in use. In comparison with the light wave position control system, the RTK system offers more accurate positioning utilizing advantages of GPS less affected by weather, time, topography or work of other boats in vicinity. The single-frequency RTK system has the following features in comparison with the dual-fi-quency RTK system: 1. Takes longer initialization time while moving; 2. Shows similar accuracy afier initialization; and 3. Is more cost-effective. We confirmed in the experiment that the single- frequency RTK system was applicable without any practical problem on board work boats where optitnum environmental condition was not always expected for installation of the antenna (shadowed radio signal, vibration due to boat operation, etc.)
