Bae, T.-S. and Kim, M., 2019. High precision GNSS positioning for the coastal navigation safety of large vessels. In: Lee, J.L.; Yoon, J.-S.; Cho, W.C.; Muin, M., and Lee, J. (eds.), The 3rd International Water Safety Symposium. Journal of Coastal Research, Special Issue No. 91, pp. 441-445. Coconut Creek (Florida), ISSN 0749-0208.Over several decades, the Global Navigation Satellite System (GNSS) has been the most important navigation equipment for vessels. Although the C/A code based absolute positioning is sufficient for most cases, a precisely guided coastal navigation is necessary for the entry and the departure of large vessels at a port. More accurate positioning and navigation can be achieved by applying the real-time kinematic (RTK) technique, which uses the carrier phases of the GNSS signals. However, the error is generally proportional to the baseline lengths between the references and the rovers due to the decorrelation of the signals. In this study, the error behavior of a single-baseline RTK (SRTK) was analyzed based on a Continuously Operating Reference Station (CORS) network in Korea. In addition, the network-based RTK (NRTK) correction was used to better estimate the position of large vessels for coastal navigation. Finally, the UP component of the vessel was constrained to the geoid to characterize coastal navigation uniquely.
