[0002] Maritime radio communications are a crucial means of ensuring safe navigation. During navigation, ships need timely access to important information such as weather, sea conditions, and navigation warnings to make informed decisions. Radio communications enable ships to maintain close contact with coastal radio stations, other vessels, and search and rescue agencies, receiving and sending various safety information in a timely manner, effectively avoiding accidents such as collisions and groundings.

[0031] Before describing the embodiments of the present application in detail, some of the related technologies involved in the embodiments of the present application are first described as follows:

[0032] Offshore and coastal waters are important shipping channels for international trade and are also active areas for the development of new forms of fisheries and the marine economy. However, some areas are characterized by numerous islands, complex waterways, unpredictable weather conditions, and complex sea conditions, posing significant navigation risks to ships. With the rapid development of shipping and offshore and coastal economic activities, the number and types of ships in these areas are increasing, and ship size, tonnage, and speed are also constantly improving. The maritime radio communication environment is becoming increasingly complex. Strengthening maritime navigational communications management capabilities to improve navigation safety is a major, long-term challenge facing maritime support departments.

[0033] In order to meet the needs of the development of shipping and marine economic activities, the navigation security department has continuously increased its investment in the construction of sea area navigation aids and support systems, and has built navigation aids and support systems based on the application of radio technology, including various visual navigation aids, navigation aid telemetry and remote control systems, VDES, RBN-DGNSS systems, AIS systems, Beidou systems, radar systems, medium and high frequency (M / HF) systems and very high frequency (VHF) systems, providing practical guarantees for the safety of ship navigation.
