Developments in modern solid state integrated circuitry have enabled fast and cost effective processing of sonar signals which has previously not been possible. The Vectorlog's combination of Doppler and EM log provides a robust, reliable system for the measurement of ship's speed with respect to the ground and to the water in both forward and athwartships axes. With the addition of accurate ship's heading a stand-alone navigation system is readily achieved.
