Assessment of sky brightness in central Portugal: the Dark Sky destination "Aldeias do Xisto" case study
Domingos Barbosa, Dalmiro Maia, Bruno Morgado +5
A combination of remote sensing techniques, open space data and field testing was developed to derive astronomical and meteorological parameters and assess Dark Sky brightness of t…
PASO -- Astronomy and Space Situational Awareness in a Dark Sky Destination
Domingos Barbosa, Bruno Coelho, Miguel Bergano +17
The Pampilhosa da Serra Space Observatory (PASO) is located in the center of the continental Portuguese territory, in the heart of a certified Dark Sky destination by the Starlight…
Tangent Velocity constraint for orbital maneuvers with Theory of Functional Connections
A. K. de Almeida, T. Vaillant, V. M. de Oliveira +9
Maneuvering a spacecraft in the cislunar space is a complex problem, since it is highly perturbed by the gravitational influence of both the Earth and the Moon, and possibly also t…
Orbit transfer using Theory of Functional Connections via change of variables
Allan K. de Almeida, Antonio F. B. A. Prado, Daniele Mortari
This work shows that a class of astrodynamics problems subject to mission constraints can be efficiently solved using the Theory of Functional Connections (TFC) mathematical framew…
Theory of Functional Connections and Nelder-Mead optimization methods applied in satellite characterization
Allan Kardec de Almeida Junior, Safwan Aljbaae, Timothée Vaillant +10
The growing population of man-made objects with the build up of mega-constellations not only increases the potential danger to all space vehicles and in-space infrastructures (incl…
