Orbital effects in satellite communication
WebA communication satellite is an artificial satellite that transmits the signal via a transponder by creating a channel between the transmitter and the receiver at different Earth locations. Telephone, radio, television, internet, … WebEarth’s orbital distance from the Sun varies a mere 2%. The exception is the eccentric orbit of Mercury, whose orbital distance varies nearly 40%. Determining the orbital speed and orbital period of a satellite is much easier for circular orbits, so we make that assumption in the derivation that follows. As we described in the previous ...

The fundamental plane is the orbital plane of the satellite. The principal direction (X-axis) points to periapsis. Y-axis is rotated 90o in the direction of orbital motion and lies in the orbital plane. Z-axis is along angular momentum vector (h) and completes the RH system.
