Research on Intelligent Ship Networked Positioning Technology Based on Communication-Sensing-Computing Fusion

Objectives The aim is to optimize the communication architecture of existing remote piloted ships to meet the challenges of network connectivity in different environments (e.g., ports, deep-sea and polar regions), and to solve the problems of capacity, latency, and security communication needs that cannot be fully met. Methods Firstly, the applicability and technical characteristics of shore-based network communication technology and satellite network communication technology are systematically sorted out, and the wireless communication requirements of remote piloted control vessels in different water environments are deeply analyzed. Based on this, a satellite-shore-based integrated network architecture based on the fusion of multiple wireless systems is proposed to deeply integrate satellite and shore-based network in order to construct an intelligent and stable ship communication system.Results An innovative communication scheme integrating satellite and shore-based technologies is designed, and an integrated network access manager model is proposed. The manager ensures that ship-shore data services can be intelligently switched between different access networks according to the demand and network conditions by giving quality of service network control technology and network slicing technology.Conclusions The integrated communication scheme provides support for intelligent maneuvering and robust communication of remote steering control ships, which helps to improve the stability, autonomy and safety of ship operation under diverse navigational network conditions.
