Inference of Single Vessel Behaviour with Incomplete Satellite-based AIS Data
Changqing Liu,Xiaoqian Chen +1 more
TL;DR: A complete process of route inference using position, speed, course over ground and time stamp information is proposed and an algorithm incorporating random deviations is presented to account for the missing sections of obtained vessel routes.

Vessel Track Recovery With Incomplete AIS Data Using Tensor CANDECOM/PARAFAC Decomposition
Changqing Liu,Xiaoqian Chen +1 more
TL;DR: This paper has analysed real AIS data obtained by satellite to form a global maritime surveillance picture and proposes to take advantage of the tensor CANDECOMP/PARAFAC (CP) decomposition to analyse three mode characteristics of the data, which are location, vessel and time.
