\(\Delta V\) is the velocity variation normal to orbital plane. \(\Delta i\) is the inclination variation. \(V\) is the orbit velocity. From the relation Eq. 6, it is possible to observe that with ∆Vs in the order of magnitude of few meters per seconds, an inclination change ...
The geostationary speed is calculated using the formula v = √(GM/r), where v is the speed, G is the gravitational constant, M is the mass of Earth, and r is the radius of the orbit. This formula is derived from the relationship between orbital speed and radius in circular orbits. ...

A two-line element set (TLE) is a data format encoding a list of orbital elements of an Earth-orbiting object for a given point in time, the epoch. Using suitable prediction formula, the state (position and velocity) at any point in the past or future can be estimated to some accuracy...

Velocity differences (VDSatellite-to-satellite tracking (SSTThe gravity field can be recovered locally from the satellite-to-satellite velocity differences (VDs) between twin-satellites moving in the same orbit. To do so, three different integral formulae are derived in this paper to recover geoid...
etc., the neighborship between a ground node and a satellite varies dramatically. Moreover, even if for the short period that a neighborship is maintained, the ever-changing distance (due to the orbital movement) between the two peering entities impacts the 'routing protocol cost' of a link...
In such satellite applications like altimetry, navigation or radar systems, this derivation is typically based upon the time delay between the transmission and reception of the signals and hence in turn depends upon the nominal velocity of the signal. Therefore, any additional delay added by the ...
The physical separation is referenced to the center of the earth. Since real earth stations are located at the surface of the earth, about 15% of the distance from the earth's center to the synchronous orbit, the apparent spacing is going to be larger than is the specified orbital spacing...

The two solutions consisted of trigonometric functions as orbital element terms. Table1presents a comparison of the formula complexity of the solutions...
