In order to filter tracks of ship targets for space-based maritime surveillance using electronic reconnaissance satellites, an extended Kalman filter (EKF) algorithm in geographic coordinates is proposed in this paper. Firstly, different methods of Dead reckoning (DR) are analysed in different coordinate systems. Then, the formula of EKF based on middle latitude sailing is derived. Finally, satellite-based...
In order for autonomous surface vessels (ASVs) to avoid collisions at sea it is necessary to predict the future trajectories of surrounding vessels. This paper investigate the use of historical automatic identification system (AIS) data to predict such trajectories. The availability of AIS data have steadily increased in the last years as a result of more regulations, together with wider coverage...
Smart manufacturing relies on a combination of different sources providing key information to support diverse activities throughout the manufacturing process. Most smart manufacturing systems focus on activities directly related to the management of robots, conveyor belts, maintenance logs, and others that ensure the process runs smoothly. An initial step to support such smart manufacturing systems...
Particle Filter (PF) is a popular sequential Monte Carlo method to deal with non-linear non-Gaussian filtering problems. However, it suffers from the so-called curse of dimensionality in the sense that the required number of particle (needed for a reasonable performance) grows exponentially with the dimension of the system. One of the techniques found in the literature to tackle this is to split the...
