Abstract This paper addresses the problem of assessing and optimizing the acoustic
positioning system for underwater target localization with range measurement. We
present a new three-dimensional assessment model to evaluate the optimal geometric
beacon formation whether meets user requirements. For mathematical tractability, it is
assumed that the measurements of the range between the target and beacons are corrupted
with white Gaussian noise with variance, which is distance-dependent. Then, the
relationship between DOP parameters and positioning accuracy can be derived by
adopting dilution of precision (DOP) parameters in the assessment model. In addition, the
optimal geometric beacon formation yielding the best performance… More >
