  2. Orbital plane of reference - Wikipedia

    en.wikipedia.org/wiki/Orbital_plane_of_reference

    The plane tangent to celestial sphere for extrasolar objects; On the plane of reference, a zero-point must be defined from which the angles of longitude are measured. This is usually defined as the point on the celestial sphere where the plane crosses the prime hour circle (the hour circle occupied by the First Point of Aries), also known as ...

  3. Orbital elements - Wikipedia

    en.wikipedia.org/wiki/Orbital_elements

    Ĵ is perpendicular to Î and with Î defines the reference plane. K̂ is perpendicular to the reference plane. Orbital elements of bodies (planets, comets, asteroids, ...) in the Solar System usually the ecliptic as that plane. x̂, ŷ are in the orbital plane and with x̂ in the direction to the pericenter .

  4. Orbital plane - Wikipedia

    en.wikipedia.org/wiki/Orbital_plane

    An orbital plane as viewed relative to a plane of reference. An orbital plane can also be seen in relative to conic sections, in which the orbital path is defined as the intersection between a plane and a cone. Parabolic (1) and hyperbolic (3) orbits are escape orbits, whereas elliptical and circular orbits (2) are captive.

  5. Satellite ground track - Wikipedia

    en.wikipedia.org/wiki/Satellite_ground_track

    Orbital inclination is the angle formed between the plane of an orbit and the equatorial plane of the Earth. The geographic latitudes covered by the ground track will range from –i to i, where i is the orbital inclination. [4] In other words, the greater the inclination of a satellite's orbit, the further north and south its ground track will ...

  6. Orbital inclination - Wikipedia

    en.wikipedia.org/wiki/Orbital_inclination

    It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object. For a satellite orbiting the Earth directly above the Equator, the plane of the satellite's orbit is the same as the Earth's equatorial plane, and the satellite's orbital inclination is 0°. The general case for a circular ...

  7. Longitude of the ascending node - Wikipedia

    en.wikipedia.org/wiki/Longitude_of_the_ascending...

    Denoted with the symbol Ω, it is the angle from a specified reference direction, called the origin of longitude, to the direction of the ascending node (☊), as measured in a specified reference plane. [1] The ascending node is the point where the orbit of the object passes through the plane of reference, as seen in the adjacent image.

  8. Orbital state vectors - Wikipedia

    en.wikipedia.org/wiki/Orbital_state_vectors

    The X/Y plane coincides with Earth's equatorial plane, with the +X axis pointing toward the vernal equinox and the Y axis completing a right-handed set. The ECI reference frame is not truly inertial because of the slow, 26,000 year precession of Earth's axis , so the reference frames defined by Earth's orientation at a standard astronomical ...
