1. 1. Development of a real-time navigation and collisionavoidance system for an autonomous naval rover : A Contribution to the Environmental Initiative for Flexible andReal-time Water Monitoring of the CatFish team

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Esmee Tackx; [2023]
   Keywords : ;

   Abstract : This thesis explores the design and optimisation of a sensor system for real-time position determination of the Fish component in the CatFish naval drone and the development of a sonar sensor system for accurate object localisation and safe navigation in dynamic and uncertain underwater conditions. Through comprehensive experimentation and analysis, this thesis demonstrates the effectiveness of the proposed sensor system and sonar sensing system in enhancing underwater navigation and obstacle avoidance capabilities.

3. 2. A Study Of Using Communication Signals As Sonar Pulses In Underwater Sensor Systems

   University essay from Uppsala universitet/Signaler och system

   Author : Erica Svensson; [2022]
   Keywords : Sonar; Communication signal; Beamforming; Underwater sensor system; WLS estimator; Detection algorithm; Position estimation;

   Abstract : Underwater communication within underwater sensor network is crucial for surveillance of coast and ocean areas. The aim of this report was to examine whether it is realistic to use the communication signal which is sent from one node to another as a sonar pulse, and in such case at what distances. READ MORE

4. 3. Autonomous Underwater Inspection of Caving Systems

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Filip Persson; [2022]
   Keywords : ;

   Abstract : This thesis aims to create and design a way for a unmanned underwater vehicle to navigateunderwater without the need for human interaction in order to carry out inspections of underwaterstructures or caving systems in a safe and effective manner. The inspection of underwater structuresor underwater caving systems is a difficult and expensive process. READ MORE

5. 4. AUV SLAM constraint formation using side scan sonar

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Marco Schouten; [2022]
   Keywords : AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation; AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation;

   Abstract : Autonomous underwater vehicle (AUV) navigation has been a challenging problem for a long time. Navigation is challenging due to the drift present in underwater environments and the lack of precise localisation systems such as GPS. Therefore, the uncertainty of the vehicle’s pose grows with the mission’s duration. READ MORE

6. 5. Design Development of a Hydrostat : Construction of a hydrostat used in an underwater SAI-unit

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Abbas Mohammadi; [2021]
   Keywords : Hydrostat; Saab Dynamics; Design; UNNDEX; Pressure;

   Abstract : Working with and providing different military and industrial solutions, SBD’s (Saab Dynamic) work also involve underwater equipment and underwater weapon (UW) systems. Nowadays, there are a number of standards that should be followed to make weapon systems safe to use, transport and handle. READ MORE
