[ Here, the term "periodic" means a certain interval, and the predetermined interval can be variably set by the ship manager.

The LoRa communication module 14 converts the transmitted ship position information into wireless data conforming to the low power long distance wireless communication format and transmits the wireless data to the space. Here, LoRa communication, which is a low-power long-distance wireless communication, is about + 14dBm in transmission, -134dBm in reception, the transmission speed is "few bytes per second", and the transmission distance is about 22km. Therefore, although it is difficult to obtain from the land-based system, the offshore can sufficiently communicate without using the satellite communication network.
