Underwater Vehicle Navigation Using Diffusion-Based Trajectory Observers [PDF]
IEEE Journal of Oceanic Engineering, 2007 This paper addresses the issue of estimating underwater vehicle trajectories using gyro-Doppler (body-fixed velocities) and acoustic positioning signals (earth-fixed positions). The approach consists of diffusion-based observers processing a whole trajectory segment at a time, allowing the consideration of important practical problems such as different
