SPEED MEASUREMENT RELATIVE TO SEA BOTTOM BY DOPPLER EFFECT SONAR

After summing up the disadvantages of measuring ship speed relative to seawater, the design principles of a Doppler sonar as well as the specific constraints imposed by the seawater medium are recalled. The errors due to these various constraints in speed measurements are reviewed. The error inventory thus obtained is then applied to mooring, to navigation on the high seas, and to dynamic positioning. In conclusion, the advantages of the Doppler sonar are summed up and the main types of apparatus developed by the Thomson-CF Company are presented.
