Technical Field

[0001] The utility model relates to the technical field of satellite positioning, in particular to a shipborne satellite positioning and communication terminal. Background Art

[0002] The Global Positioning System (GPS) uses satellites to accurately locate objects. This system ensures that at any given moment, any point on Earth can simultaneously observe four satellites, enabling navigation, positioning, and timing. It can be used to guide aircraft, ships, vehicles, and individuals safely and accurately along selected routes to their destinations on time. It can also be used for tracking devices such as mobile phones.

[0003] Existing technologies, such as CN205263313U and road transport vehicle satellite positioning systems, can use on-board terminals to not only collect all information about road transport vehicles during their travel, including driver identity information, real-time positioning information, vehicle status information, alarm information, etc., but can also upload all information to the system platform in real time and interact with the system platform. The system platform can monitor and dispatch transport vehicles in real time based on the positioning information uploaded by the on-board terminal in real time, and can also provide drivers with early warning services such as fatigue driving and speeding based on the uploaded vehicle driving data, as well as process alarm information, to provide safety protection for drivers and vehicles, so that people and vehicles can work in a safe and orderly road environment.

When vehicles or ships enter some remote or backward areas during operation, the Beidou antenna has certain limitations. The system's data transmission, ship navigation positioning, and emergency rescue efficiency are too low. At the same time, information cannot be obtained quickly, reducing its practicality.
