Inductive modem for 6000-m Aquadopp

Inductive communication makes it possible to deploy open ocean mooring systems where data are transferred to shore at regular intervals.  Typically, several instruments (current meters, CT-sensors, etc) are fitted with magnetic coils and clamped at various points along the deep water mooring cable (made from a steel wire with an outer polyurethane jacket).  The communication along the mooring line  is controlled by a surface unit that can address each device and tell it when to transfer the data.  If the surface unit is connected to a satellite transmitter, the data can then be sent in near real time to shore.

We are pleased to announce that we have released the Aquadopp IM6000, which completes a year-long task to permit inductive communication with our Aquadopp current meters.  The first five units of the IM6000 have already been successfully delivered.
