<p>PURPOSE:To detect a self position, and grasp a condition over the sea with high accuracy by detecting the self position, taking a picture around the self position, and thereby transmitting information on the self position and the image taken. CONSTITUTION:An information transmitting buoy 1 is made up of a cylindrical buoy main body 1a, and of a buoy head section 1b, and a GPS receiving antenna 3, a geostationary satellite antenna 2 exchanging receiving/transmitting with a geostationary satellite and a bioinformation receiving antenna 4 are housed in the buoy head section 1b. The buoy main body 1a is provided with underwater motors 17a and 17b with screws 16a and 16b as a means for rotating the buoy 1 or turning it around. And a GPS receiver 13 and a video camera 18 are contained in the buoy main body 1a where the self position is detected by the GPS receiver 13 and an image around the circumference is taken by the video camera 18. Image signals are processed by an image processing means 19 so as to be transmitted to a terrestial station together with position information from the GPS receiver 13 via the geostationary satellite. On the contrary, commands from the terrestial station can be received.</p> |
