Effects of the Eccentricity of a Perturbing Third Body on the Orbital Correction Maneuvers of a Spacecraft
(Hindawi Publishing Corporation, 2014-01-01)
The fuel consumption required by the orbital maneuvers when correcting perturbations on the orbit of a spacecraft due to a perturbing body was estimated. The main goals are the measurement of the influence of the eccentricity ...
Analytical direct planetary perturbations on the orbital motion of satellites
(2013-01-01)
An analytical expansion of the disturbing function arising from direct planetary perturbations on the motion of satellites is derived. As a Fourier series, it allows the investigation of the secular effects of these direct ...

Perturbation of the Sun on Frozen Orbits Around Mars
(2019-11-04)
This work presents a study related to the perturbation of the Sun in the orbital evolution of artificial satellites on frozen orbits around Mars. The effect generated by the non-sphericity of Mars is considered. Frozen ...
Some orbital characteristics of lunar artificial satellites

Closed poly-trajectories and Poincaré index of non-smooth vector fields on the plane
(2013-04-01)
This paper is concerned with closed orbits of non-smooth vector fields on the plane. For a class of non-smooth vector fields we provide necessary and sufficient conditions for the existence of closed poly-trajectorie. By ...

FROZEN ORBITS AROUND EUROPA
(World Scientific Publ Co Pte Ltd, 2012-10-01)
Low-altitude, near-polar orbits are very desirable for scientific missions to study the natural satellites of the planets of the Solar System, such as Europa, that is one of the natural satellites of Jupiter. The problem ...
Influence of nonsphericity of planetary satellites and perturbation of the third-body on the artificial satellites motion
(2011-12-01)
Some orbital characteristics of lunar artificial satellites is presented taking into account the perturbation of the third-body in elliptical orbit and the non-uniform distribution of mass of the Moon. We consider the ...
