Patent ID: 7778622

Claim:
A positioning and recording information system for rescue at sea, wherein: the positioning and recording information system is implemented with a multi-hopping technique; and at least two stations are utilized, and each said station transmits, receives and stores information using digital communication and Internet access for mobile vessels, the information about each station being processed into data packets being position data, the data packets temporarily being stored in temporary repositories of the stations, the system comprising: at least one fixed station of the stations, representing a destination station, comprising hopping software and a communication device and processing received data packets into applicable information for positioning; a plurality of mobile stations of the stations, comprising hopping software and communication devices, and configured to transmit and store the data packets in a signal-reception area; the system comprising means for: transmitting and storing data packets from a first mobile station to second and third mobile stations by using the hopping software; receiving and storing the data packets in the second and third mobile stations through the communication devices; after receiving and storing in the second mobile station the data packets transmitted from the first mobile station, transmitting first feedback data packets from the second mobile station to the first mobile station by using the hopping software, and storing the first feedback data packets in the second mobile station and the first mobile station; after receiving and storing in the third mobile station the data packets transmitted from the first mobile station, transmitting second feedback data packets from the third mobile station to the first mobile station by using the hopping software, and storing the second feedback data packets in the third mobile station and the first mobile station; transmitting and storing a data packet from the second mobile station to the third mobile station by using the hopping software; receiving and storing the data packet in the third mobile station through the communication devices; after receiving and storing in the third mobile station the data packets transmitted from the second mobile station, transmitting third feedback data packets from the third mobile station to the second mobile station by using the hopping software, and storing the third feedback data packets in the third mobile station and the second mobile station; and eventually receiving and storing the data packets in the destination station.
