WebApr 12, 2024 · The effects of environmental perturbations, such as the Earth's oblateness (J2), atmospheric drag, and solar pressure, are also taken into account. Floquet theory is utilized to analyse the stability of the ring-tethered three-satellite formation. The impact of motion plan attitude and initial system states on the motion forms, including spin ... WebNodal precession. Nodal precession is the precession of the orbital plane of a satellite around the rotational axis of an astronomical body such as Earth. This precession is due to the non-spherical nature of a rotating body, which creates a non-uniform gravitational field. The following discussion relates to low Earth orbit of artificial ...
WebThe J2 Perturbation (first-order) propagator accounts for secular variations in the orbit elements due to Earth oblateness. This propagator does not model atmospheric drag or solar or lunar gravitational forces. J2 is a zonal harmonic coefficient in an infinite series representation of the Earth's gravity field.

WebIn celestial mechanics, the standard gravitational parameter μ of a celestial body is the product of the gravitational constant G and the mass M of the bodies. For two bodies the parameter may be expressed as G (m 1 +m 2 ), or as GM when one body is much larger than the other. For several objects in the Solar System, the value of μ is known ...

Using this property of J2 perturbations, we can manipulate our orbit so that the RAAN changes at a rate of 360 degrees per year, keeping the orbit in the same orientation with respect to the Sun.
