Long Baseline Underwater Acoustic Location Technology

Abstract

Acoustic Synthetic Baseline (ASBL); Direct sequence spread spectrum (DSSS); Doppler velocity log (DVL); Inertial navigation system (IMU); Inertial navigation system (INS); Long baseline (LBL); Multiuser long baseline (MULBL); Short baseline (SBL); Sparse long baseline (Sparse LBL); Super short baseline (SSBL); Ultra-short baseline (USBL) System Structure The long baseline underwater acoustic positioning system consists of a question and answerer (transceiver) and a transponder (beacon). The transceiver is usually installed on the target to be measured, such as surface ships, submarines,
