Coconut Creek (Florida), ISSN 0749-0208. Various research activities are being conducted every year in the coastal and inland water areas of Korea. Among them, location accuracy is very important for coastline change survey, depth survey, and coastal route analysis. VRS and DGPS are commonly used in coastal and inland areas. VRS is a type of Network RTK that offers high location accuracy and ease of use. However, due to the limitations of the Network RTK method, VRS is not able to significantly degrade or use its location accuracy unless the survey area is located within the network. On the other hand, DGPS has a position accuracy of about 1m, which is ...
