Analyze of multistage transfer orbit to reach the GEO orbit in a rotational symmetric gravitational field

چکیده
A circle at an altitude of approxmately 35 786km above the equator is known as the geostationary arc. Geostationary orbit, or GEO as it is called, is discovered because of its advantegs. It is situated circular in the equatorial plane, moving tn step with the earth rotation. The geostationary orbit time is close to a solar day which has some advantageous properties. The orbit covers the most of the earth. Moreover, the satellites i GEO are fixed in proportion to each point of the earth surface. Hence, it is possible to construct a system with a single satellite that yields time continuous coverage of an area on the earth. The technology of geostationary orbit is well depeloped and proven today. Other advantegs are there is minimal effect and stable signal strength due to constant ground satellite range in such a orbit.

Determination of the best-fitting reference orbit for a LEO satellite using the Lagrange coefficients
Linearization of the nonlinear equations and iterative solution is the most well-known scheme in many engineering problems. For geodetic applications of the LEO satellites, e.g. the Earth’s gravity field recovery, one needs to provide an initial guess of the satellite location or the so-called reference orbit. Numerical integration can be utilized for generating the reference orbit if a satelli...

Introduction: Diagnosis of orbital foreign body (FB) penetration is usually obvious when part of the FB is still attached at the entry wound (1). However, the depth and course of the FB in this case was not visible. Case Report: A 5-year old female presented with a pencil penetrating the left orbit. A computed tomography (CT) scan showed that the pencil penetrated the left orbit (extraseptal)...
