专利汇可以提供Distress communication method by geostationary satellite专利检索,专利查询,专利分析的服务。并且PURPOSE: To detect a distressed position by utilizing a geostationary satellite by obtaining information of said position from a reception power level of a distress signal radio wave at each multi-beam antenna even when no distressed position information is sent from a transmitter of a wrecked ship.
CONSTITUTION: When a wrecked ship exists in a beam irradiation area of an antenna beam 13-i and when a distress signal from a transmitter of the wrecked ship is found out, the distress signal radio wave is caught by the antenna beam 13-i, the signal passes through a feed horn 17-i, received and detected by a receiver 18-i and converted into a reception power level signal and inputted to a signal processing circuit 19. The signal processing circuit 19 applies A/D conversion signal to each reception power level signal and sends the result to an earth station 9 in a signal format corresponding to each antenna beam. Since the sending point of the distress signal exists in the beam irradia tion area of the antenna beam having the maximum reception power level, the earth station finds out the distressed position.
