Spacecraft motion around artificial equilibrium points
(2018-02-01)
The main goal of this paper is to describe the motion of a spacecraft around an artificial equilibrium point in the circular restricted three-body problem. The spacecraft is under the gravitational influence of the Sun and ...
Determination of thrusts to generate artificial equilibrium points in binary systems with applications to a planar solar sail
(2019-01-30)
In this work, the artificial equilibrium points for a general two-body system are derived, visualized, and summarized as functions of the direction of the thrust, for several directions. The results for the Sun-Earth system ...
Solar reflectors about the Sun-Earth artificial collinear equilibrium points
(2016-01-01)
Simple climate models help to explain the natural variability of the Earth's climate system. These models show that Earth's climate can switch from a stable warm state to a cool state and is sensitive to relative small ...
Searching for orbits to observe the poles of celestial bodies
(2020-11-15)
The objective of the present paper is to show a method to find orbits near artificial equilibrium points for a satellite equipped with a continuous thrust that allows it to stay near the poles of a celestial body. The ...
Searching for artificial equilibrium points to place satellites above and below L3 in the Sun-Earth system
(2017-10-01)
Regarding practical applications of L3 of the Sun-Earth system, there are few studies with the goal of placing a spacecraft at this point, or in orbit around it. One of the main problems in placing a spacecraft near this ...
SEARCHING FOR ARTIFICIAL EQUILIBRIUM POINTS TO PLACE SATELLITES ABOVE AND BELOW L-3 IN THE SUN-EARTH SYSTEM
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2017-10-01)
Regarding practical applications of L-3 of the Sun-Earth system, there are few studies with the goal of placing a spacecraft at this point, or in orbit around it. One of the main problems in placihg a spacecraft near this ...
Attitude stability analyses for small artificial satellites
(2013-01-01)
The objective of this paper is to analyze the stability of the rotational motion of a symmetrical spacecraft, in a circular orbit. The equilibrium points and regions of stability are established when components of the ...
Stability analysis of the attitude of artificial satellites subject to gravity gradient torque
(Univelt Inc, 2008-01-01)
Using a canonical formulation, the stability of the rotational motion of artificial satellites is analyzed considering perturbations due to the gravity gradient torque. Here Andoyer's variables are used to describe the ...
