Electronic rescue contact and location system to rescue people in disaster

摘要

Electronic distress call and position finding system for rescuing distressed people has a receiver with a screen and a distress call transmitter. For evaluating the distress call, it requires the positions of both the receiver and transmitter components. The positions (A) of the receiver (1) and (B) of the distress call transmitter (2) are established by their GPS modules from the data of specialized satellites (4), which orbit the earth on stationary orbits. The distress call transmitter radios its position (B) to the receiver. From the two positions, the distance and direction of the distress call transmitter are calculated. If the system is used for diving, the switched-on receiver remains on the ship, and the distress call transmitter is secured to the diver so that it cannot get lost. When a diver is drifting away, the distress call transmitter is switched on, the system begins to work, and his distance and direction with respect to the ship are displayed on the screen. Then, the rescue of the diver is initiated in a well-aimed manner.
