R&D for an innovative acoustic positioning system for the KM3NeT neutrino telescope

Abstract An innovative Acoustic Positioning System for the km 3 -scale neutrino telescope has been designed and is under realization within the KM3NeT Consortium. Compared to the Acoustic Positioning Systems used for the km 3 demonstrators, ANTARES and NEMO Phase 1, this new system is based on the “all data to shore” concept and it will permit the enhancement of detector positioning performances, reduction of costs and its use as real-time monitor of environmental acoustic noise.
