Abstract

For many underwater location and navigation requirements, and especially those in the deep ocean, acoustic methods are likely to remain the principal solution. A wide range of examples and their main features are reported. Basic design considerations and the environmental and operational factors limiting performance are discussed. Relative performance may be good but absolute geodetic accuracies are limited by the accuracies of navigation at the sea surface.
