Abstract:The objective of this research, is to design a navigation system that can be integrated into Ortega’s submersibles. The insights gathered in the research phase resulted in a combination of an Inertial Navigation System (INS) and Doppler Velocity Log (DVL) to be the most suitable system. In contradiction to other available methods, this combination could handle almost all environments and activities. The Spatial FOG INS and the Syrinx DVL have high accuracy characteristics, and enable for custom made casings, which can be designed such that installation takes minimum time and effort. In the fi nal design, which is chosen out of three concept designs, the Spatial FOG is placed in a waterproof casing, together with a Global Navigation Sattelite System (GNSS) antenna. The casing is placed in the upper middle of the submersible, behind the second seat. The GNNS had to be placed at altitude, and the INS performs best when placed near the centre of gravity of the submersible. The DVL’s transducer heads must be in direct contact with water, and aligned facing the seafl oor. In the submersible, is placed more to the front, away from thrusters and motors. To protect the transducer heads, it is placed in a hull, such that is nicely concealed with the submersible’s shell. Sensor implementation and attachment is performed including the installation steps. Solidworks models and parts lists are included.
