Nowadays, the rapid development of outdoor sports and adventure leads to the increase of the frequency of missing accidents. On the other hand, it becomes much more convenient and efficient for the criminals to escape with the help of new technologies. So we have developed a long-distance raids targeted field search and rescue system which utilizes RSSI ranging and Kalman filtering algorithm to realize remote positioning and dynamic supervision management only by a mobile phone with a SIM card, without any additional terminal equipment.
