The ANTARES experience Absolute positions of LBL tranceivers: • Determined from surface (ship GPS) • Accuracy improved via LBL triangulation (tens cm) Detector angular uncertainty σ (horizontal) = 0.13° σ (vertical) = 0.06° Giorgio Riccobene, LNS-INFN VLVnT 2009, Athens October 13 –15 ,2009
R&D for an integrated Acosutic Positioning System Major innovations compared to the ANTARES and NEMO Phase 1 experience • Fully time phased and synchronised array of transmitters and receivers • “All data to shore” philosophy Hydrophone data is rate fully sustainable Better/faster data analysis tools on shore Large room for associated science et al. • Use of audio professional electronics components / data transmission protocols Reduce costs Improve reliability Integrate APS in the detector DAQ and data transmission electronics Improve data exchange with associated science • Auto-calibrating and multi-frequency LBL integrated with the DAQ chain Giorgio Riccobene, LNS-INFN VLVnT 2009, Athens October 13 –15 ,2009
