Abstract
This report has been generated in support of the DRDC AUV (autonomous underwater vehicle) Docking Technology Investment Fund (TIF) project. The report provides a level of detail for the conceptual rendezvous and Stage 1 docking procedures. Three acoustic systems are required to conduct Stage 1 docking: an AUV beacon signal generator, an AUV vector sensor-based homing signal receiver, and underwater modems. The role of these acoustic systems is discussed and a suggested procedure is developed. Design issues for the acoustic systems are explored and potential designs for the beacon and vector sensor systems are presented. The beacon is a new, but relatively simple device. The proposed vector sensor is a second generation version of an existing DRDC homing system. The modems are expected to be a variant of a commercially available system. The Teledyne telesonar modems are the suggested solution as they are the only modems to support a full underwater networking protocol and they have a data streaming capability that will be important for final stage docking.
