Conventional wisdom holds that laser-based systems cannot handle high mobility due to the
strong directionality of laser light. We challenge this belief by presenting Lasertag, a generic …

Driven by the requirements of inter-satellite link antenna for tracking mechanism with two
degree-of-freedom (DoF), this paper proposes a 2-DoF over-constrained rotational parallel …

Multi-objective optimization of a typical parallel tracking mechanism considering parameter
uncertainty is carried out in this paper. Both dimensional and sectional parameters are …

Line-of-sight laser communication application scenarios are numerous including land,
mobile, maritime, airborne and space platforms for conventional and tactical utilization …

New technologies are emerging to enable and support physical, implicit and explicit
collaborations. They are essential for dealing with increasingly complex systems in …

Parallel tracking mechanism with varied axes has great potential in actuating antenna to
track moving targets. Due to varied rotational axes, its finite motions have not been modeled …

Increasing demand for rail transportation results in denser and more high-speed usage of
the existing railway network, making new and more advanced vehicle safety systems …

Free-space optical (FSO) communication has attracted extensive attention in recent years.
To maintain a reliable FSO link, two main issues need to be addressed: beam drift and …

The inertial reference unit (IRU) serves as a master reference for acquisition, tracking and
pointing (ATP) system due to its ability to maintain stability with respect to inertial frame …

The initial pointing unit of the line of sight (LOS) operating in the open-loop mode is an
important part of the space laser communication system, which directly determines the size …
