    This study discusses a modular and practical solution that enables secure communication during natural disasters with GPS signals of Morse code. It is an innovative solution that aims to effectively coordinate emergency services and aid teams by providing an alternative communication channel for the communication infrastructure damaged during natural disasters. In cases such as earthquakes, which are always on the agenda of our country and should be, the solution of emergency aid and communication infrastructure problems has become a focused topic. The aim of the study is to provide an alternative communication channel in cases where this communication is damaged. A specially designed radio transmitter circuit, GPS module and MORSE alphabet coding system constitute the basic components of our study. This solution will enable rapid intervention and coordination by transmitting real-time location information to local and international aid teams. The Arduino platform will allow us to adapt to different scenarios by providing flexibility and customizability. The radio transmitter circuit is designed for effective communication on the 2549Hz frequency, which is the UN SOS (United Nations Emergency Radio Frequency Line) line. The GPS data obtained with the help of sensors is encoded in the form of the MORSE alphabet with the help of a microcontroller and transmitted to the international helpline, and the location information is transmitted quickly and reliably. This system was tested for a short time in a laboratory environment and in an environment where communication was partially interrupted. Being accessible and applicable in terms of cost calculation increases the importance and effectiveness of the study in terms of appealing to every user. As a result, we aim to provide a vital alternative in cases where communication networks are inadequate, and to provide social benefit and scientific contribution.
