Abstract :
The reconstruction of submarine tracks for tactical exercises is formulated in this paper as a nonlinear, discrete-time, fixed interval smoothing problem, and the extended Kalman filter is used to obtain a solution. The operation of the smoothing algorithm is illustrated with the reconstruction of a 5-h exercise run.
