heal.abstract	When performing underwater operations, submerged personnel, vessels and devices need constantly updated positioning information. A constellation of sea surface crafts of either conventional or buoy type, broadcasting broadband acoustic signals underwater, allows establishing positioning service to submerged end-users. This work investigates the underwater acoustic channel when used for transmission of positioning information. This task includes the appropriate description of the underwater medium and the impairments involved, e.g. ambient noise, chromatic dispersion, multipath and Doppler effects etc. In this end, time-frequency, time-scale, and frequency-scale representations of time-varying channels provide certain advantages, including a derivation of the rake receiver.
