Possible navigation methods for unmanned underwater vehicles are described and the limits of their accuracy are reviewed. The best approach seems to be the use of a sparse network of bottom-laid acoustic transponders giving only sporadic coverage of the area, together with a high-accuracy dead reckoning system based on a bottom-referenced acoustic log and a low-cost inertial navigator used as a precision gyrocompass. The likely performance and operating costs are discussed. Accuracy requirements are considered in detail.
