Abstract: Fishermen's livelihoods often require them to cross country borders, which can unknowingly put them at risk of being captured or killed. The lack of easily identifiable sea borders between countries exacerbates this problem. To address this issue, a "Border Alert System for Fishermen Using GPS" has been developed to help fishermen become aware of country borders. The system employs Global Positioning System (GPS) and Global System for Mobile Communication (GSM) technologies.

The GPS receiver is used to determine the current location of the fishing boat, and the present latitude and longitude values are sent to a microcontroller unit. The controller unit compares these values with predefined values to identify the current location. The border alert system then notifies the fishermen when they are approaching the nautical border. The region is divided into two zones: normal and warning. When the boat is in the normal zone, the LCD displays "normal zone," making it clear that the boat is in a safe area. If the boat moves further and enters the warning zone, the LCD displays "warning zone," alerting the fishermen of their proximity to the border.
