Herein, at the request of the Korea Coast Guard, we propose a LoRaWAN-based small observation system that can quickly find survivors at sea by measuring the speed, direction, and distance between a ship and mobile device in real time. This system was implemented and verified in the early stages of rescue after maritime vessel accidents. GPS signals often transmit considerable errors; therefore, correction algorithms using an improved triangulation method are required to accurately indicate the direction of the currents in real time.
The remainder of this paper is organized as follows: Section 1 describes rescue operations following maritime accidents. Chapter 2 describes the methods and theories for GPS triangulation and features of LoRaWAN communication. The critical distance error-correction algorithm for GPS signals and its improvement are explained and expanded. Section 3 discusses the design and analysis of the small-draft observation system. Section 4 presents the testing and implementation of both ship-to-shore environments. Finally, Section 5 concludes the study with expected impacts and future effects.
