Abstract :
A procedure for calculating ocean currents from submarine set and drift is described. Relationships for the response length of the submarine to velocity perturbations are given. These lengths are found to be 3-10 boat lengths, and they represent a limit to the spatial resolution of the current measurements. A procedure for the in-situ calibration of the submarine speed sensor is described. An example shows that the current vectors are consistent from one leg of the submarine track to another and with satellite observations. Ocean current measurement capability is presently being integrated into an oceanographic monitoring system for tactical applications
