Today the offshore industry requires more from its navigation and positioning technology; More accuracy, more integrity, more range or depth and more data. With the advent of super fast wireless communications in the home and office, it is often the case that the physical limitations of the environment in which we work underwater is less well understood, especially when you combine the demands for "More" with those of "Less" from the purse holders. This paper will deliver an insight into a technology that is being used by ROV, AUV, DP Vessels, Ships and the Subsea Production Hardware to, not only position and navigate underwater, but also to communicate, without the use of cables It will include details of recent implementations of these technologies including the "Underwater GPS" and "Wireless Control System". Applications and experience with 21st Century Acoustic Technology will set the audience thinking of the other possibilities open to them.
