For example, the Moon has an orbital period that is the same as its rotational period. In essence, it is tidally locked to the Earth, which means that it always presents the same face to us as it orbits around our planet. And during the course of its orbit, it also appears larger an...
from kepler’s 3 rd law, we know the time period of a satellite, and by substituting it in the above formula, we get \(\begin{array}{l}k=\frac{gmm}{2r}\end{array} \) kinetic energy can never be negative for any force. also read: kepler’s laws potential energy of a ...

In the case of a satellite orbiting the Earth. Would the relative velocity calculated by the Vis Viva equation the same as the orbital speed of the satellite? If the satellite is in an ellipse, would Vis Viva give the circular tangential velocity Vt=rω, or would it give the orbital velo...
Calculating Sputnik I's Orbital Period 1.Sputnik I, the first artificial satellite to circle the planet (October 1957) had a mean orbital radius of 6957 km. Compute its period in seconds 2. I am using the equation T^2 = R^3/C 3. I converted 6957 km to AU's which equals 4.638 E...
The work deals with the secular perturbations only as they are the accumulative and the most effective forces on the satellite’s orbit. This has been processed by averaging over the fast angle of the orbit. This ensures a longer lifetime for the sat which is the main concern of the work...
FIG. 1 shows a space vehicle, a transfer orbit of which is followed by a method according to the invention, as well as a GNSS satellite used for the implementation of this method; FIG. 2 illustrates the relation existing between a local orbital frame and a satellite frame; FIG. 3 illustr...
1. A satellite for removing space debris from near Earth orbit and positioned over an entry point of a polar cusp, the satellite comprising: an antenna to direct a local EM wave to interact with a solar electromagnetic (EM) wave at the entry point of the polar cusp; and control systems ...
For a satellite constellation consisting of multiple orbital planes, a nonplanar multi-target flyby/intercept can be important as a way to traverse all satellites. However, at the same time, co-orbital multi-target flyby/interception, as another perspective, also has some importance. For geostati...
Thevariations in the remaining orbital elements of thissatellite (e, i, and ω) exhibit peculiar qualitative fea-tures that are atypical of similar orbits for the distantsatellites of the giant planets.In general, the solar perturbations in e,i have no-ticeable long-period (and secular for ...
