Abstract
Determining the precise location of a ship navigating on a lake is of utmost importance for various logistical and safety reasons. However, this task can become particularly challenging when operating in regions with limited or no access to the Internet. Fortunately, advancements in technology, specifically the Internet of Things (IoT) utilizing Low Power Wide Area Network (LPWAN) technology, have offered a robust solution to address this issue. LPWAN technology enables long-range data transmission without being reliant on traditional internet connectivity.
In the context of our research, a LoRaWAN end node is employed equipped with LGT92, along with three gateways sourced from two different vendors, to effectively track the real-time position of a ship. To gauge the effectiveness of our system, let’s conduct experiments and obtained significant results. One noteworthy finding was that the communication range between one of the gateways and the LoRaWAN end node extended to 2.5 kilometers when utilizing the RAK 7243 gateway. In contrast, the Dragino LG308 gateway impressively stretched this range to 5.7 kilometers. All three gateways to broaden the tracking coverage area and ensure comprehensive monitoring are strategically deployed.
Our research's primary focus was tracking a ship's journey spanning 16 kilometers from Balige to Onanrunggu port. Throughout our experimentation, it is confirmed that the ship's precise coordinates, including latitude and longitude, were accurately transmitted from the end node on the ship to the designated gateway. This crucial position data was then seamlessly transmitted to the cloud. This real-time tracking capability proved invaluable, allowing for constant oversight and decision-making support during the ship's journey
