	Inclination - Facts, Information, and Encyclopedia Reference article
		In particular, the inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit.
		It is the angular distance of the orbital plane from the plane of reference (usually the primary's equator or the ecliptic), normally stated in degrees.
		And in particular, for the Earth, the inclination or obliquity of the ecliptic is the angle between the plane of the ecliptic and the equator.

	Orbital inclination change - Wikipedia, the free encyclopedia
		Orbital inclination change is an orbital maneuver aimed at changing the inclination of an orbiting body's orbit.
		An important subtlety of performing an inclination change is that Keplerian orbital inclination is defined by the angle between ecliptic North and the vector normal to the orbit plane, (i.e.
		This means that inclination is always positive and is entangled with other orbital elements primarily the argument of periapsis which is in turn connected to the longitude of the ascending node.

	Earth Observatory Glossary
		The elliptical path of a satellite orbit lies in a plane known as the orbital plane.
		Inclination is the angle between the equatorial plane and the orbital plane measured counter-clockwise at the ascending node.
		An inclination of 180 degrees would mean the satellite is orbiting the equator, but in the opposite direction of the Earth's rotation.

	Cosmos: The SAO Encyclopedia: Orbital Inclination
		Along with the argument of perihelion and the ascending node, the orbital inclination (i) is one of the elements that must be specified in order to define the orientation of an elliptical orbit.
		Although the ecliptic provides a convenient reference plane from which to measure the orbital inclinations of planets in our Solar System, a different reference plane should be adopted for each of the planetary systems discovered around other stars.
		Note: Orbital inclination should not be confused with obliquity - the tilt of a planet's axis relative to the orbit.

	inclination
		Orbital inclination (i) is the angle between the orbital plane of an object and a reference plane that passes through the body being orbited.
		The inclination of a planetary orbit in the Solar System is measured from the ecliptic (the plane of Earth's orbit around the Sun).
		Axial inclination is the angle between a planet or moon's rotation axis and its orbit; in the case of a star, the reference plane is usually that of the celestial sphere.

	Orbital Mechanics
		Inclination is the angular distance between a satellite's orbital plane and the equator of its primary (or the ecliptic plane in the case of heliocentric, or sun centered, orbits).
		Polar orbits (PO) are orbits with an inclination of 90 degrees.
		Orbital transfer becomes more complicated when the object is to rendezvous with or intercept another object in space: both the interceptor and the target must arrive at the rendezvous point at the same time.

		The orbital plane always goes through the center of the earth, but may be tilted any angle relative to the equator.
		Inclination is the angle between the orbital plane and the equatorial plane.
		The intersection of the equatorial plane and the orbital plane is a line which is called the line of nodes.

	Orbital Operations Manual - Aligning, Syncing, and Docking with a Space Station
		An inclination of 90 degrees is an orbit that crosses over both the north and south poles and passes over the equator at two points.
		Inclination and LAN are both measures of the orientation of an orbital plane.
		The inclinations of Mir and the ISS is also quite different from that of the moon or any other planet, making them poor places from which to start interplanetary travels, because a large orbital plane change is required.

		Have the students draw lines from the centre of a scaled Earth at angles representing their latitudes, the ISS inclination latitude, and other latitudes.
		The students can pick a latitude, follow the same procedures of drawing tangent lines, and find the length the hypotenuse line “H” (being the ISS line) would have to be to just meet with the horizon line for that latitude.

		Although the initial display shows the system's actual orbital tilt (at an inclination of 128°) from the visual perspective of an observer on Earth, the orbital inclination of any planet that may be discovered someday around either star would likely be different from those of the habitable zone orbits depicted here.
		According to the new Sixth Catalog of Visual Orbits of Binary Stars, Stars A and B have an average separation of 12.6 AUs (a semi-major axis of 1.81" at a HIPPARCOS distance estimate of 20.74 ly) in a highly eccentric orbit (e= 0.58).
		The orbital period takes 42.15 years to complete and is inclined 128° from the perspective of an observer on Earth (Staffan Soderhjelm, 1999; and W.P. Hirst, 1950, page 458; and 1947).

		EarthWatch requests authority to change the inclination of the orbital plane of QuickBird-1 from 52§ to 66§, and the inclination of QuickBird-2 from 52 to 98.
		In this Order, we conclude that we should also leave orbital inclination decisions regarding remote-sensing satellite systems to licensees, because they are in a better position to tailor their systems to meet the particular needs of their customers.
		This conclusion is based on the fact that the Bureau has found in other circumstances that a change in orbital inclination by itself does not increase the potential for interference, and because no one opposed EarthWatch's requested changes in orbital inclination.

	INCLINE
		The reason all the others have an inclination of 51.6 degrees is because that's the orbital inclination of ISS, and the Shuttles must use that inclination in order to rendezvous with ISS.
		Columbia's last mission was at 150nm with an orbital inclination of 39 degrees because it was a science flight, and in no way involved with ISS.
		BTW, the orbital inclination is the angle of the orbit relative to the equator, and has nothing to do with the angle of descent on re-entry.

		This is another cataclysmic variable in which caution is needed in the interpretation of the `orbital elements'.
		The orbital eccentricity and time of periastron derived from the velocity-curve are in good agreement with the same quantities derived from the light-curve.
		The orbital elements are derived from a heterogeneous set of observations and slightly different values can be found for each element (including the period) for different selections of the observations to be used.

		It can be characterised by stating the orbital altitude (height of the spacecraft above the Earth's surface) and the orbital inclination (the angle of the satellite's orbital plane to the Earth's equatorial plane).

		The inclinations available from a given launch site are usually restricted by range safety (that is, places one does not want to drop pieces either on purpose or in case of abort).
		Florida launches are confined to a narrow range of inclinations by the requirement that they fly over the ocean, in case of a launch failure.
