Precise Positioning Service Status for Maritiem in Asia Area

Abstract

GNSS positioning is the most important positioning system in the maritime environment, and the accuracy requirements are increasing as technologies such as autonomous ships, marine drones, and automatic docking. In the land environment, local network-based precise positioning services are provided, but there are technical limitations as the number of user increases. In addition, in the maritime environment, as the demand for precise positioning services increases for autonomous ships, marine drones, and automatic docking, various precise positioning services that can be utilized by various users in both land and maritime fields have recently been provided. This paper analyzes the current status of precise positioning services and their performance in the Asian environment.
