Relative Orbit Geometry Through Classical Orbit Element Differences
Journal of Guidance, Control, and Dynamics, 2004The relative orbit geometry of a spacecraft formation can be elegantly described in terms of a set of orbit element differences relative to a common chief orbit. For the nonperturbed orbit motion, these orbit element differences remain constant if the anomaly difference is expressed in terms of the mean anomaly and all semimajor axes are equal.

Equinoctial orbit elements - Application to artificial satellite orbits
Astrodynamics Conference, 1972The matrizant of the two-body problem is developed in terms of elements that are free from singularities for zero eccentricities and zero- and ninety-degree inclinations. Retrograde equinoctial elements eliminate the singularity for inclinations near 180 degrees, with only minor changes in the expressions for the matrizant.

Visual Binaries; Orbital Elements
1981The present author’s earlier astrometric treatise (1967) contains a chapter on visual binaries, which is repeated here with minor changes. We shall be primarily interested in the orbital effects of visual binaries on the paths of the components as measured on a background of reference stars (Chapters 1 Iff).

Formation design in elliptical orbit using relative orbit elements
Acta Astronautica, 2012Abstract A new set of relative orbit elements is strictly defined through spherical geometry. The exact transformation equations between the new relative orbit elements and classical-orbital elements are derived. A new relative motion model with no singularity problem is derived based on the relative orbit elements, which are suitable for both ...

I was hom in Bradford, West Yorkshire in 1950 and by the age of ten I had developed an interest, like many children, in prehistoric animals and astronomy. In 1962 the first American piloted orbital flights began and my teacher at Wibsey Junior School, Mr Slater, brought a radio into the classroom so that we could listen to these flights.

Elements of a Chemical Orbital Theory
2009Interaction is important in chemistry. Interactions of atoms form chemical bonds. Bonds interact with each other in molecules to determine the molecular properties. Interactions of molecules give rise to chemical reactions. Electrons control atoms, bonds, and molecules.

Orbital correlation of space objects based on orbital elements
Research in Astronomy and Astrophysics, 2016Orbital correlation of space objects is one of the most important elements in space object identification. Using the orbital elements, we provide correlation criteria to determine if objects are coplanar, co-orbital or the same. We analyze the prediction error of the correlation parameters for different orbital types and propose an orbital correlation ...

romanticism for data fanciers and ham radio fans, watching sunsets and satellite launches — staging and making perceptible the activities and patterns of motion of “invisible” forms of technology that seem to be capable of independent action. the user has the opportunity to follow the race of NOAA14 and meteor 3–5 — two earth observation satellites ...

Modelling of Periodic Relative Orbits Using Orbital Element Method
2006 IEEE Aerospace Conference, 2006Several future spacecraft missions are envisioned that have small ride-along satellites to inspect and service a large parent satellite. The so called escort or inspector satellites orbit around the parent satellite and with the help of onboard imaging capabilities and other sensors assess spacecraft damage in the event of an on-orbit mishap.

Journal of Guidance, Control, and Dynamics, 2008
A SURVEY of orbit element sets was conducted as part of a research and technology development task [1] which sought to develop feedback control laws and prototype tools for computing feasible, low-thrust transfers in multibody environments, where at least two celestial bodies exert significant gravitational influence on the spacecraft.
