  2. Geospatial PDF - Wikipedia

    en.wikipedia.org/wiki/Geospatial_PDF

    The PDF format is widely accepted and is considered the de facto standard for printable documents on the web. This means that users do not require the any proprietary plug-in to read geospatial PDFs created following the PDF 1.7 specification, which was published as ISO 32000-1 standard. [3]

  3. Geosynchronous satellite - Wikipedia

    en.wikipedia.org/wiki/Geosynchronous_satellite

    Satellites in geostationary orbit. A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky that is typically some form of analemma.

  4. Geosynchronous orbit - Wikipedia

    en.wikipedia.org/wiki/Geosynchronous_orbit

    A special case of geosynchronous orbit is the geostationary orbit (often abbreviated GEO), which is a circular geosynchronous orbit in Earth's equatorial plane with both inclination and eccentricity equal to 0. A satellite in a geostationary orbit remains in the same position in the sky to observers on the surface. [1]

  5. Geostationary transfer orbit - Wikipedia

    en.wikipedia.org/wiki/Geostationary_transfer_orbit

    The orbital inclination of a GTO is the angle between the orbit plane and the Earth's equatorial plane. It is determined by the latitude of the launch site and the launch azimuth (direction). The inclination and eccentricity must both be reduced to zero to obtain a geostationary orbit.

  6. List of satellites in geosynchronous orbit - Wikipedia

    en.wikipedia.org/wiki/List_of_satellites_in...

    A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. Popularly or loosely, the term "geosynchronous" may be used to mean geostationary. [1] Specifically, geosynchronous Earth orbit (GEO) may be a synonym for geosynchronous equatorial orbit, [2] or geostationary Earth orbit. [3]

  8. GeoPDF - Wikipedia

    en.wikipedia.org/wiki/GeoPDF

    GeoPDF products use geospatial PDF as a container for maps, imagery, and other data used to deliver an enhanced user experience in TerraGo applications. However, GeoPDF products conform to published specifications including both the OGC best practice for PDF georegistration as well as Adobe's proposed geospatial extensions to ISO 32000, making ...

  9. Graveyard orbit - Wikipedia

    en.wikipedia.org/wiki/Graveyard_orbit

    De-orbiting a geostationary satellite requires a delta-v of about 1,500 metres per second (4,900 ft/s), whereas re-orbiting it to a graveyard orbit only requires about 11 metres per second (36 ft/s). [1] For satellites in geostationary orbit and geosynchronous orbits, the graveyard orbit is a few hundred kilometers beyond
