In the prior art CN110346822B, three positioning methods, namely 125KHz, LORA and GPS, are used, but the LORA and the GPS both use foreign positioning technologies, which is not beneficial to the localization process, and the LORA has many shortfalls in the aspects of capacity, efficiency, self-interference of lever and the like, so that the positioning accuracy of the 125KHz is difficult to achieve in-centimeter level for a fishing boat.
