An underwater target point positioning system is provided that can realize a positioning system capable of acquiring underwater position coordinates with high accuracy with a simple configuration and at low cost. An underwater target point positioning system (1) includes a main body having an ...
Optimal Sensor Placement for Underwater Target Positioning with Noisy Range MeasurementsAutonomous underwater vehicles (AUVs) are becoming ubiquitous due in part to the flexibility and versatility that a number of them display in the execution of individual and cooperative tasks. These characteristics, ...
The first one is the underwater positioning system that uses a vessel mounted transceiver to detect the range and bearing to a target using acoustic signals. The second one is Doppler Velocity Log (DVL) that has been used to provide navigation information for ships, Remotely Operated Vehicles (...
This paper addresses the problem of optimal acoustic sensor placement for underwater target localization in 3-D using range measurements only. By adopting an estimation theoretical framework, the optimal geometric sensor formation that will yield the best achievable performance in terms of target positio...
