Abstract

PURPOSE:To perform quick and sure rescue activities by measuring position coordinates with a satellite navigational device to determine the speed and course, synthesizing these data with the rescue signal for transmission, and allowing the rescuer side to know the present position and past position of a distressed person. CONSTITUTION:When a distressed person throws a buoy on the sea in distress, the power feed circuit of a device is turned on by a ditching judging circuit 2 and a system control circuit 3. A satellite receiving circuit 4 is operated to receive radio waves from a satellite, the latitude/longitude coordinates of the present position are determined by a coordinates calculating circuit 6, and the drifting speed and course are determined by a navigational information calculating circuit 7 from the coordinates data. Radio waves are modulated by a modulating circuit 8 with the coordinates data of the present position determined by the coordinates calculating circuit 6, the position coordinates data of the track to the present time after ditching, and the drifting speed and course data determined by the navigational information calculating circuit 7, and they are transmitted from a transmitter 9. A rescuer receives the transmitted radio waves, demodulates them, and easily searches for the distressed person based on the read data.
