An underwater communications system is provided that transmits electromagnetic and/or magnetic signals to a remote receiver. The transmitter includes a data input. A digital data compressor compresses data to be transmitted. A modulator modulates compressed data onto a carrier signal. An electrically insulated, magnetic coupled antenna transmits the compressed, modulated signals. The receiver that has an electrically insulated, magnetic coupled antenna for receiving a compressed, modulated signal. A demodulator is provided for demodulating the signal to reveal compressed data. A de-compressor de-compresses the data. An appropriate human interface is provided to present transmitted data into text/audio/visible form. Similarly, the transmit system comprises appropriate audio/visual/text entry mechanisms.

Mobile device underwater communications system and method

Communications system

The present invention provides a system and apparatus for transferring electronic data and/or power from one station to another by means of a transportable pod comprising a solid state memory device and further provided with an inductively linked, electrically insulated connector. The transportable pod comprises a battery which is used to power a remote host docking station, which may be used in an underwater environment for the collection of subsea data. The transportable pod can be transferred alternately from a home docking station, where it is charged up, and where it's stored data is uploaded and to a remote host docking station where is provides power, and where it collects and stores data collected by the remote host docking station.

Inductively coupled data and power transfer system and apparatus

Underwater communication system

The present invention relates to a transfer system for providing wireless data transfer, electrical power transfer and navigation between a mobile subsea vehicle and a deployed subsea station that uses acoustic and electromagnetic carrier signals for wireless communication and navigation. An inductive connector is provided for power transfer between mobile subsea vehicle and a deployed subsea station without conductive contact.

Subsea transfer system providing wireless data transfer, electrical power transfer and navigation

An environmental monitoring system including at least one underwater measurement device and a transmitter for transmitting data from the measurement device to an above water station using a magnetically coupled antenna.

Underwater communications

An underwater inspection system comprising an underwater mobile inspection station () having an electromagnetic antenna (), the mobile station () being adapted to capture inspection data and use the electromagnetic antenna () to send information relating to the inspection data to a underwater electromagnetic receiver that has a fixed electromagnetic antenna ().
