A NOVEL MODEL FOR ORIENTATION OF LINEAR OPTICAL SATELLITE IMAGES BASED IN THE ADAPTATION OF THE ORBIT-ATTITUDE MODEL
(Univ Federal Parana, Centro Politecnico, 2019-01-01)
In this paper a novel model to orient a pushbroom linear optical satellite image is proposed. This one is based in the adaptation of the Orbit-Attitude model for use of the Modified UCL Kepler platform model. It has only ...
Constraining the orbital orientation of eta Carinae from H Paschen lines
(WILEY-BLACKWELL, 2009)
During the past decade, several observational and theoretical works have provided evidence of the binary nature of eta Carinae. Nevertheless, there is still no direct determination of the orbital parameters, and the different ...
Azimuthal dependence of the Garton-Tomkins orbit in crossed magnetic and electric fields
(2016-08-11)
Work on classical closed orbits in the diamagnetic Kepler problem is predominately focused on the chaos observed in the polar launch angle as opposed to the azimuthal launch angle. This is due to atomic systems, along with ...
Sub-optimal orbital maneuvers for artificial satellites
(2008-12-01)
The determination of a specific orbit and the procedure to calculate orbital maneuvers for artificial satellites are problems of extreme importance in the study of orbital mechanics. Therefore, the transferring problem of ...
Anisotropic spin-orbit induced splitting of intersubband spin plasmons
(EDP Sciences, 2013-01)
The anisotropic splitting of intersubband spin plasmons, resulting from spin-orbit coupling, is studied by angle-resolved inelastic light scattering on a [001]-oriented GaAs/AlGaAs quantum well. Confirming theoretical ...
Orientação de imagens CBERS-2B usando o modelo rigoroso de colinearidade com dados orbitais
(Universidade Federal de Uberlândia (UFU), 2011-09-01)
Atualmente, o imageamento orbital é uma das principais técnicas de coleta de informações geoespaciais. Embora os sistemas orbitais sejam equipados com sensores de orientação direta (GNSS, giroscópios, sensores de estrelas, ...
