Orbit ground track equation
WebOrbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft.The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation.Orbital mechanics is a core discipline within space-mission design and control.

The speed can’t vary as long as the satellite has a constant orbital radius — that is, as long as it’s going around in circles.
WebOct 1, 2024 · The condition for repeating ground track orbits can be written as (10) (11) where R and N are both positive integers, , which means the period Jupiter rotates relative to the spacecraft’s orbit. Equation (11) means the spacecraft runs R circles in N Jupiter nodal days. The nodal period of the motion of the spacecraft can be expressed as (12) WebSatellite’s ground track is the path on the surface of the Earth, which lies exactly below its orbit. The ground track of a satellite can take a number of different forms depending on the values of the orbital elements. Orbital Equations. In this section, let us discuss about the equations which are related to orbital motion. Forces acting on ...
