  2. 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]

  3. Satellite navigation - Wikipedia

    en.wikipedia.org/wiki/Satellite_navigation

    GNSS augmentation is a method of improving a navigation system's attributes, such as accuracy, reliability, and availability, through the integration of external information into the calculation process, for example, the Wide Area Augmentation System, the European Geostationary Navigation Overlay Service, the Multi-functional Satellite ...

  4. Southern Appalachian low-elevation pine forest - Wikipedia

    en.wikipedia.org/wiki/Southern_Appalachian_low...

    The Southern Appalachian low-elevation pine forest is a forest system that occurs in Indiana, Kentucky, Tennessee, Alabama, Virginia, North Carolina, South Carolina, and Georgia. It is found in the lower elevations of the southern Appalachian Mountains and adjacent Piedmont and Cumberland Plateau, extending into part of the Interior Low Plateaus.

  5. European Geostationary Navigation Overlay Service - Wikipedia

    en.wikipedia.org/wiki/European_Geostationary...

    The European Geostationary Navigation Overlay Service (EGNOS) is a satellite-based augmentation system (SBAS) developed by the European Space Agency and EUROCONTROL on behalf of the European Commission. Currently, it supplements GPS by reporting on the reliability and accuracy of their positioning data and sending out corrections.

  6. 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.

  8. Satellite ground track - Wikipedia

    en.wikipedia.org/wiki/Satellite_ground_track

    A special case of the geosynchronous orbit, the geostationary orbit, has an eccentricity of zero (meaning the orbit is circular), and an inclination of zero in the Earth-Centered, Earth-Fixed coordinate system (meaning the orbital plane is not tilted relative to the Earth's equator). The "ground track" in this case consists of a single point on ...

  9. Weather satellite - Wikipedia

    en.wikipedia.org/wiki/Weather_satellite

    Geostationary weather satellites orbit the Earth above the equator at altitudes of 35,880 km (22,300 miles). Because of this orbit , they remain stationary with respect to the rotating Earth and thus can record or transmit images of the entire hemisphere below continuously with their visible-light and infrared sensors.
