Application of GAP Technique in Ship Observation System

Data exchange is widely used in ship observation system. The introduction of GAP technique into ship observations using iridium communication not only provides sound solution to problems arising in real-time interaction between business operation networking system and external networking system, but also achieve the purpose of interactive trasmission, secured sharing and efficient utilization of hydrometeorological data. This article provides a detailed introduction to the definition, function, and composition of GAP. A secure real-time interaction system between internal and external networks is introduced in detail, including the network structure, the functional implementation, and the security analysis of the ship measurement and reporting system. This system not only provides security based on physical isolation, but also achieves high-speed data exchange.
