Abstract
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 lower than that of VRS. However, DGPS is widely used for location measurement in the coastal area due to its wide service range. PPP is the most recently developed satellite positioning method. PPP can be used anywhere in Korea, like DGPS, while providing accuracy similar to VRS's positioning accuracy. However, PPP is still an early stage positioning technology and has a long convergence time to show high positioning accuracy and high complexity of use. Therefore, it is not used for research activities in actual coastal and inland water. In this paper, we present our PPP positioning system and analyze the results of PPP using our PPP positioning system, VRS and DGPS positioning presented in coastal and inland areas of Korea. In this paper, we compare and analyze the accuracy of three positioning methods and present the results.
