Book Description
The Naval Postgraduate School Autonomous Underwater Vehicle (AUV), Phoenix, has a well developed lower level architecture (Execution level) while the upper, Strategic and especially the Tactical, levels need refinement. To be useful in the fleet an easier means of creating mission code for the Strategic level is required. A software architecture needed to be implemented at the Tactical level on-board Phoenix which can accommodate multi-processes, multi- languages, multiprocessors and control hard real time constraints existing at the Execution level. Phoenix also did not have a path replanning capability prior to this thesis. The approach taken is to provide Phoenix a user friendly interface for the autogeneration of human readable mission code and the creation and implementation of a Tactical level control architecture onboard Phoenix to include path replanning. The approach utilizes Rational Behavior Model (RBM) architectural design principles. This thesis focuses on the Officer of the Deck and replanning at the Tactical level, and refinement of the Captain at the Strategic level. While further testing is necessary, Phoenix is now capable of behaving as a truly autonomous vehicle. Results of this thesis show that nontechnical personnel can generate Prolog code to perform missions on-board Phoenix. Path replanning and obstacle avoidance software are also implemented. Most important this thesis demonstrates successful operation of all three levels of the RBM architecture on-board Phoenix.

Book Description
Because of range limitations imposed by speed and power supplies convert launch and recovery of Autonomous Underwater Vehicles (AUVs) near the operating area will be required for their use in many military applications. This report contains source code implemented on the Phoenix AUV in support of recovery in a small stationary tube. Implementation involves the development of low-level behaviors for sonar and vehicle control, mil-level tactics for recovery planning, and a mission-planning system for translating high-level goals into an executable mission. Sonar behaviors consist of modes for locating and tracking objects, while vehicle control behaviors include the ability to drive to and maintain a position relative to a tracked object. Finally, a mission-planning system allowing graphical specification of mission objectives and recovery parameters is implemented.

Book Description
Because of range limitations imposed by speed and power supplies, covert launch and recovery of Autonomous Underwater Vehicles (AUVs) near the operating area will be required for their use in many military applications. This thesis documents the implementation of precision control and planning facilities on the Phoenix AUV that will be required to support recovery in a small tube and provides a preliminary study of issues involved with AUV recovery by submarines. Implementation involves the development of low-level behaviors for sonar and vehicle control, mid-level tactics for recovery planning, and a mission planning system for translating high-level goals into an executable mission. Sonar behaviors consist of modes for locating and tracking objects, while vehicle control behaviors provide the ability to drive to and maintain a position relative to a tracked object. Finally, a mission-planning system allowing graphical specification of mission objectives and recovery parameters is implemented. Results of underwater virtual world and in-water testing show that precise AUV control based on sonar data and its use by higher-level tactics to plan and control recovery. Additionally, the mission-planning expert system has been shown to reduce mission planning time by approximately two thirds and results in missions with fewer logical and programming errors than manually generated missions.

Book Description
Specific tasking/total military mission concepts for subsea tasks have been developed that demand substantially more endurance and range than can be provided by manned submersibles and remotely operated vehicles, respectively. Small autonomous unmanned systems can provide the best combination of speed, endurance, range, depth capacity, and flexibility needed to make these concepts realizable. As the U.S. military has continued to identify more and more tasks that can be performed by autonomous systems, the NPG has heightened its research efforts to develop an experimental autonomous underwater vehicle (AUV) to address these requirements. A series of NPS AUV simulation systems have been developed that couple knowledge-based mission planning and control systems with 3-D visualization (graphics) workstations that communicate across an interprocess communications network. Development of these simulation systems have produced an extremely useful 'laboratory environment' for rapid prototyping of AUV planning, navigation, and control subsystems software. This thesis updates and extends the formats of functionality of the simulation systems to include a Mission Planning and Control Workstation as a prototype for use aboard AUV deployment vessels, upgrades mission profiles, and incorporates improvements to the software interface between the mission planning and control subsystem and the 3-D visualization subsystem. Keywords: Three dimensional display systems; Interactive graphics; Theses.(edc).

Book Description
The Naval Postgraduate School (NPS) is developing an AUV, Phoenix. The Phoenix has the capability of precise navigation, however too much time is needed to validate a new section of code. NPS is also developing a virtual AUV, which has the capability of being networked, having flexible missions, and having a quick feedback of results when validating new portions of code. The virtual AUV has a drawback of never being tested for real world precision. This thesis discusses the steps taken to combine these two sets of control code to obtain the maximum functionality that will drive either the virtual or actual AUV and produce a faster feedback response to newly developed code. As a result of this effort, the newly developed control code has successfully driven both the actual and virtual AUVs and provides a means for readily validating new code. Also this new control code has given the AUV research group the ability to perform distributed software development, test all AUV hardware from either the onboard or offboard computers, conduct flexible missions, and test missions in the virtual world prior to conducting them with the AUV.

Book Description
The absence of common software platforms for Autonomous Underwater Vehicle (AUV) mission planning and analysis is an ongoing impediment to collaborative work between research institutions, their partners, and end users, This thesis details the design and implementation of a distributable application to facilitate AUV mission planning and analysis. Java-based open-source libraries and a component-based framework provide diverse functionalities. The extensible Markup Language (XML) is used for data storage and message exchange, Extensible 3D (X3D) Graphics for visualization and XML Schema-based Binary Compression (XSBC) for data compression. The AUV Workbench provides an intuitive cross-platform-capable tool with extensibility to provide for future enhancements such as agent-based control, asynchronous reporting and communication, loss-free message compression and built-in support for mission data archiving. This thesis also investigates the Jabber instant messaging protocol, showing its suitability for text and file messaging in a tactical environment. Exemplars show that the XML backbone of this open-source technology can be leveraged to enable both human and agent messaging with improvements over current systems. Integrated Jabber instant messaging support makes the NPS AUV Workbench the first custom application supporting XML Tactical Chat (XTC).

Book Description
The growing use of autonomous air, surface, ground and underwater systems is continually demonstrating new military and commercial possibilities and applications. The state of the art in the planning and control of autonomous underwater vehicles (AUVs) is largely precarious because AUVs provide infrequent feedback, operate autonomously for long periods of time and yet have little knowledge of their dynamic environment. Consequently, mission planning and control is typically conducted based on human expert knowledge of vehicle capabilities, some level of observed environmental conditions and ad-hoc optimization with little assistance from computers. While the human expert offers a significant ability to mentally process data, the result typically lacks numeric and quantitative analysis of alternatives. Navigation of AUVs in the complex ocean environment involves time dependent dynamics, resulting in a problem that is computationally prohibitive for the use of brute force optimization techniques. Although some research has been conducted for specific types of missions, and "greedy" global-optimization approaches have been investigated, no systematic and coherent approach to the requirement exists. We propose a dynamic multiple criteria decision support system (DSS) that considers dynamic and episodic ocean phenomenon to provide reasonable and in-context recommendations with respect to the stated objective and subjective mission goals. Multi-criteria decision analysis (MCDA), analytic network process (ANP) and fuzzy sets are used in the model to reduce the vehicle routing solution space and maximize time-on station in adverse environments. The proposed system can be an added hierarchical layer on the top of a mission planning system currently under development by the United States Navy.
