Abstract

Underwater communication has mainly been driven by the Navy under specific circumstances and challenges. Currently used here are conventional technologies using acoustic transmission, which can only realize data rates up to several kilobits. From the perspective of the operators of a submarine there is a logical prioritization towards covert operation combined with an evolution in data rates. The use of unmanned underwater vehicles (UUVs) in submarine operation enhances the capabilities of submarine missions. The fibre optic link however hampers the submarine’s movements underwater and does not provide the anticipated communication “at speed and depth”. Cassidian Optronics has developed and patented a special optical method¹, wherein these difficulties can be overcome by means of an “optical GPS” . The report describes the underlying process and thereby gives an outlook on the possibilities opened up.
