	Geosynchronous orbit
		A geosynchronous orbit may be defined as one with an orbital period (the time needed to orbit once around the Earth) that matches the rotation rate of the Earth.
		A geostationary orbit is a special case of a geosynchronous orbit.
		A satellite is in a geostationary orbit when it appears stationary from the point of view of an observer on the Earth's surface.

	Space Elevators and Tether Systems
		Geosynchronous orbit is special since this is the distance at which an object orbiting the earth would have to travel around the earth at the same rate the earth rotates, the point at which a geosynchronous object’s centripetal force exactly cancels out its gravitational force.
		If an object is within geosynchronous orbit and is moving around the earth with the same period (time per orbit) as the period of rotation of the earth then its gravitational force would exceed its centripetal force and pull it down.
		On the space leg of the trip to geosynchronous orbit high speed would be desirable so as to shorten the journey, however during the short atmospheric leg, slow speeds would reduce the lose of energy to air resistance, or even render this effect negligible.

	CelesTrak: "Basics of the Geostationary Orbit"
		While each satellite will complete its orbit in the same time it takes the earth to rotate once, it should be obvious that the geosynchronous satellite will move north and south of the equator during its orbit while the geostationary satellite will not.
		Orbits with non-zero eccentricity (i.e., elliptical rather than circular orbits) will result in drifts east and west as the satellite goes faster or slower at various points in its orbit.
		Since the geostationary orbital plane is not coincident with the plane of the earth's orbit (the ecliptic) or that of the moon's orbit, the gravitational attraction of the sun and the moon act to pull the geostationary satellites out of their equatorial orbit, gradually increasing each satellite's orbital inclination.

	Geosynchronous Orbit (Site not responding. Last check: 2007-10-25)
		The original idea of geosynchronous communications satellites was published by the British science fiction writer Arthur C. Clarke in the early 50's.
		The idea of geosynchronous satellites is to find an orbit over the equator in which the satellite revolves around the earth at the same rate that the earth spins on its axis.
		Recalling the relationship between force and period of circular motion, the period, radius and mass of the satellite are related to the centripetal force pulling the satellite away from a straight path to a circular orbit.

	Satellite TV Technical Information
		These satellites are in geosynchronous orbit, meaning that they rotate around the earth in the same direction as it is rotating, in order to stay directly above the area that they are broadcasting to.
		In order for the satellites to remain in orbit, there has to be a balance between the pull of the earth's gravity and the centripetal force of the satellite's orbit, which is pulling away from earth.
		This is possible by adjusting the altitude and orbiting velocity of the satellites.

	Physics Simulation and Java - Lecture 13B: Introduction to Java Networking
		Notice how much slower the satellite moves in a large orbit, and how much longer it takes to complete an orbit than when it is closer to the Earth.
		A mathematical relationship exists between the orbital period and the size of the orbit, i.e., the distance between the center of the Earth and the satellite.
		The relationship states that the square of the orbital period is proportional to the cube of the size of the orbit.
