  2. Global Positioning System - Wikipedia

    en.wikipedia.org/wiki/Global_Positioning_System

    The Global Positioning System ( GPS ), originally Navstar GPS, [2] is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. [3] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near ...

  3. United States Space Surveillance Network - Wikipedia

    en.wikipedia.org/wiki/United_States_Space...

    The United States Space Surveillance Network (SSN) detects, tracks, catalogs and identifies artificial objects orbiting Earth, e.g. active/inactive satellites, spent rocket bodies, or fragmentation debris. The system is the responsibility of United States Space Command and operated by the United States Space Force and its functions are:

  4. Weather satellite - Wikipedia

    en.wikipedia.org/wiki/Weather_satellite

    GOES-16, a United States weather satellite of the meteorological-satellite service. A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary ...

  5. Geostationary orbit - Wikipedia

    en.wikipedia.org/wiki/Geostationary_orbit

    Geostationary orbit. A 5° × 6° view of a part of the geostationary belt, showing several geostationary satellites. Those with inclination 0° form a diagonal belt across the image; a few objects with small inclinations to the Equator are visible above this line. The satellites are pinpoint, while stars have created star trails due to Earth's ...

  6. List of USA satellites - Wikipedia

    en.wikipedia.org/wiki/List_of_USA_satellites

    List of USA satellites. This is a list of satellites and spacecraft which have been given USA designations by the United States Air Force. These designations have been applied to most United States military satellites since 1984, and replaced the earlier OPS designation. As of June 2022, USA designations have been assigned to 331 space satellites.

  7. Geosynchronous satellite - Wikipedia

    en.wikipedia.org/wiki/Geosynchronous_satellite

    A geostationary satellite is in orbit around the Earth at an altitude where it orbits at the same rate as the Earth turns. An observer at any place where the satellite is visible will always see it in exactly the same spot in the sky, unlike stars and planets that move continuously. Geostationary satellites appear to be fixed over one spot ...

  8. Geosynchronous orbit - Wikipedia

    en.wikipedia.org/wiki/Geosynchronous_orbit

    A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day ). The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to ...

  9. GOES-16 - Wikipedia

    en.wikipedia.org/wiki/GOES-16

    GOES-17 →. GOES-16, formerly known as GOES-R before reaching geostationary orbit, is the first of the GOES-R series of Geostationary Operational Environmental Satellites (GOES) operated by NASA and the National Oceanic and Atmospheric Administration (NOAA). GOES-16 serves as the operational geostationary weather satellite in the GOES East ...
