114 untethered UUV dives: lessons learned
The Ocean Engineering Division at the Naval Command Control and Ocean Surveillance Center RDT&E Division (NRaD) has developed and field tested two successive untethered, supervisory controlled UUV systems: a prototype, and an improved model. These robotic vehicle systems were part of the Advanced Unmanned Search System (AUSS) programme. It was only after the prototype was fielded, many lessons were learned. As a consequence of the prototype experience, the improved model was developed. The second system was a complete redesign, using state-of-the-art subsystems and technologies. The resulting product was both capable and reliable, yet flexible, creating a plethora of system evolutionary possibilities. Sea tests, improved tactics, and systems engineering became synergistic and interactive. AUSS involved pioneering research in underwater search and in UUV systems. Important knowledge was also gained in systems analysis, system engineering, and program evolution. Invaluable experience was gained from 114 successful untethered dives. The purpose of this paper is to share many of the lessons learned during the AUSS program.
Evolution of a Search System: Lessons Learned with the Advanced Unmanned Search System.
Abstract : This document follows the evolution of the Advanced Unmanned Search System (AUSS) and the lessons learned. The events leading up to the development of the AUSS, the subsystem focus, systems engineering, and the interactive development and field testing are all included.
Advanced Unmanned Search System (AUSS) Surface Navigation, Underwater Tracking, and Transponder Network Calibration
Abstract : This report describes the surface navigation and underwater tracking system capabilities used in support of the Advanced Unmanned Search System (AUSS) development program. Various surface navigation and underwater tracking modes and the hardware involved are discussed. Navigation and tracking performance objectives are stated, and where available, at-sea test data results are presented to support claims. The hardware and software necessary for the deployment and calibration of a typical underwater tracking range, used for monitoring AUSS position, are discussed....
