This paper presents the motivation for the design and development of an entirely new,
correlation sonar velocity sensor aimed specifically at the rapidly maturing market for
AUV platforms and associated instrumentation. The chosen implementation places
particular emphasis on producing a product with very high accuracy, vector velocity
output which is maintained down to zero speed and when operated in a hover manoeuvre.
Other essential features of the sonar are its small size and low power budget.
Following discussion of the features, advantages and proposed uses of the new velocity
log, computer simulations of system performance are described which support the choice
of primary design parameters. Finally, a description is given of the developed hardware
system which is suitable for fitting to AUV platforms.
