The website provides a spreadsheet containing details of all the satellites, which can be downloaded. Listings are from west to east (decreasing longitude in the Western Hemisphere and increasing longitude ...
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.
Satellite imagery. The first images from space were taken on the sub-orbital V-2 rocket flight launched by the U.S. on October 24, 1946. Satellite image of Fortaleza. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments ...
A geostationary orbit, also referred to as a geosynchronous equatorial orbit [a] ( GEO ), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude above Earth's equator, 42,164 km (26,199 mi) in radius from Earth's center, and following the direction of Earth's rotation . An object in such an orbit has an orbital period equal to ...
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 ...
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 (hovering over the same spot on the equator ). [1]
This is a list of satellite map images with missing or unclear data. Some locations on free, publicly viewable satellite map services have such issues due to having been intentionally digitally obscured or blurred for various reasons of this. [1] For example, Westchester County, New York asked Google to blur potential terrorism targets (such as ...
Quasi-Zenith satellite orbit QZSS animation, the "Quasi-Zenith/tundra orbit" plot is clearly visible.The Quasi-Zenith Satellite System (QZSS), also known as Michibiki (みちびき), is a four-satellite regional satellite navigation system and a satellite-based augmentation system developed by the Japanese government to enhance the United States-operated Global Positioning System (GPS) in the ...
