Self-organising satellite constellation in geostationary Earth orbit [PDF]

, 2015
This paper presents a novel solution to the problem of autonomous task allocation for a self-organizing satellite constellation in Earth orbit. The method allows satellites to cluster themselves above targets on the Earth’s surface.

Constellation Design for Channels Affected by Phase Noise

, 2012
In this paper we optimize constellation sets to be used for channels affected by phase noise. The main objective is to maximize the achievable mutual information of the constellation under a given power constraint.

Experimental Demonstration of Geometrically-Shaped Constellations Tailored to the Nonlinear Fibre Channel [PDF]

, 2018
A geometrically-shaped 256-QAM constellation, tailored to the nonlinear optical fibre channel, is experimentally demonstrated. The proposed constellation outperforms both uniform and AWGN-tailored 256-QAM, as it is designed to optimise the trade-off ...

Harmonization of space-borne infra-red sensors measuring sea surface temperature [PDF]

, 2020
Sea surface temperature (SST) is observed by a constellation of sensors, and SST retrievals are commonly combined into gridded SST analyses and climate data records (CDRs).

Topological aberration of optical vortex beams and singularimetry of dielectric interfaces

, 2012
The splitting of a high-order optical vortex into a constellation of unit vortices, upon total reflection, is described and analyzed. The vortex constellation generalizes, in a local sense, the familiar longitudinal Goos-H\"anchen and transverse Imbert ...
