Abstract
Search and rescue operations play a vital role in saving lives in emergency situations. Knowing the exact latitude, longitude coordinates and directional angles can ensure effective and efficient operations when search and rescue personnel are operating in remote or hazardous environments. This paper presents the design and implementation of a search and rescue device based on magnetic compass. The device uses ESP8266 as the primary control module, combining GPS module for positioning and magnetic compass module for angle of acquisition. The information collected is corrected and transmitted to ESP8266 to provide feedback, which is displayed on the OLED screen to search and rescue personnel. The test results showed that the device performed well in all of the selected test scenarios, with an average accuracy of 0.61°for directional angle data and 1.17 meters for latitude and longitude coordinate data. This improved search and rescue device can improve search and rescue operations and increase the chances of successful rescues.
