The KM3NeT infrastructure comprises two water Cherenkov detectors in the Mediterranean Sea. 
Each detector is composed of multiple optical modules that are subject to movement due to deep-sea currents.
To ensure an accurate reconstruction of neutrino events, the position of each optical module needs to be tracked continuously.
The positioning system is based on set of acoustic emitters placed on the seabed and acoustic receivers integrated into the optical modules. 
A global fit of the acoustic data is used to determine the position of each detector element every ten minutes. 
The movement of the detector can be compared to measurements of deep-sea currents.
