Test Particle Motion around an Oblate Planet
Icarus, 1994Abstract Ring flow kinematic features, such as, e.g., the shape of the narrow rings of Uranus or the streamlines of density waves of Saturn's rings, can be analyzed by fitting ring occultation data with m-lobe shapes with constant elements and constant precession rates. The orbital parameters thus obtained (e.g., the semimajor axis, the eccentricity)

RISE AND SET TIME OF A SATELLITE ABOUT AN OBLATE PLANET
AIAA Journal, 1963Summary: A technique is presented for the determination of the rise and set times of a satellite about an oblate planet. The solution depends on the ability to determine the rise and set eccentric anomalies from a single transcendental equation. The solution of the transcendental equation is facilitated greatly by an approximating technique.

Relative Satellite Motion About an Oblate Planet
Journal of Guidance, Control, and Dynamics, 2002A solution to the relative motion problem for satellites is constructed that is based on nearly circular reference periodic orbits and Floquet theory for the relative motion. This solution conceptually resembles the Clohessy-Wiltshire solution for relative motion, but includes all zonal harmonics of the Earth's gravitational field.

Perturbation of a satellite orbiter by the oblateness of the primary planet
Celestial Mechanics, 1976The perturbation of an orbiter around a large satellite of a giant planet (Jupiter, Saturn, Uranus or Neptune) produced by the oblateness of the planet is investigated. The perturbing force of theJ2-term (general case) and theJ4-term (special case of small eccentricity and inclination) is expanded in an appropriate form and the main term and the ...

Analytic Solution to the Relative Orbital Motion Around an Oblate Planet
AIAA Guidance, Navigation, and Control Conference, 2009The paper offers a vectorial approach to the J2–perturbed relative orbital motion. The model uses mean orbital elements in order to derive closed form expressions for the relative position and relative velocity with respect to the LVLH frame attached on a main satellite.

The possible motions of a satellite about an oblate planet
Celestial Mechanics, 1983The regions of motions of a satellite for given values of energy and angular momentum about polar axes are shown. Special attention is paid to the circular equatorial orbits which have been shown to be Hill stable. The anomalistic and the nodal period for the motions near to the circular equatorial orbits have been found.

Optimal Satellite Formation Establishment about an Oblate Planet
AIAA Guidance, Navigation, and Control Conference, 2011This paper suggests a new approach for generating bounded motion between two spacecraft orbiting an oblate planet. As opposed to most works, the suggested approach does not rely on averaging the osculating orbital elements. Instead, the problem is formulated in local-vertical local-horizontal coordinates, without approximating the gravitational ...

PERIODIC ORBITS ABOUT AN OBLATE PLANET
1963Abstract : Periodic solutions of the equations of motion of a satellite of an oblate planet are investigated, using methods developed by Poincare (1892). The treatment covers both critical and non-critical angles.

Saturn's rings: Resonance about an oblate planet
Icarus, 1982Abstract Classical resonance theory is extended to include corrections due to Saturn's oblateness. A single classical resonance splits into a band structure, with individual resonances almost evenly spaced in radius from the planet. When applied to Saturn's rings this theory predicts, in detail, the structure of Cassini's division.

Perturbations by the oblateness of the Earth and by the planets in the motion of the Moon
Celestial Mechanics, 1982Perturbations in the motion of the Moon are computed for the effect by the oblateness of the Earth and for the indirect effect of planets. Based on Delaunay's analytical solution of the main problem, the computations are performed by a method of Fourier series operation.
