Problems solved by technology
Once the ship enters the open sea or the sea area of a neighboring country, it will encounter a situation where GPRS cannot communicate, resulting in the inability of GPS positioning information to be transmitted back to the country. Only satellite phones can be used to establish contact with the country.

Description
technical field [0001] The invention relates to the technical field of satellite networks, in particular to a shipborne satellite multi-mode terminal based on the satellite internet of things. Background technique [0002] In recent years, the growth rate of land transportation and ocean freight transportation business has accelerated significantly. As the main carrier of contemporary international bulk cargo transportation, trucks and containers have become a symbol of global economic integration. Economic development provides convenient conditions. [0003] At present, most shipborne IoT devices use GPS positioning + GPRS communication technology, which can only realize the networking function when there is a mobile communication network. Once the ship enters the high seas or the waters of neighboring countries, it will encounter the situation that GPRS cannot communicate, resulting in the inability of GPS positioning information to be transmitted back to the country, and...
