Resumen

The design and development of an acoustic beacon as part of the positioning system for the underwater neutrino telescope KM3NeT is presented. Acoustic positioning system is used to monitor the position of the optical sensors of the telescope (with 10 cm accuracy over distances of about 1 km), in which the acoustic beacons are the active elements. The acoustic beacon is able to generate high-power short signals in a frequency range of 20-60 kHz, hence signal processing techniques can also be used to improve the performance of the positioning system.
