Description

The ANTARES neutrino telescope consists of 12 string lines containing the optical detectors. Sea water currents results on drifts for these strings of several meters from the vertical. However, muon track reconstruction is based on precise arrival of Cherenkov photons to the optical modules (~1 ns) and knowledge of the optical module position with respect to a fixed reference system with the corresponding resolution (~20 cm). The relative positioning of the detector is monitored combining two systems: an acoustic system giving the 3D-position of five hydrophones along the line and a set of tiltmeter-compasses giving the local tilt and orientation of each OM storey. With this information, a global fit of the string shape leads to the 3D-positioning of all OMs within the requirements. In this paper, the positioning system is described, and the performance and results for the first years of operation in ANTARES are shown.
