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.
A number of weather satellites are also present in geosynchronous orbits. Not included in the list below are several more classified military geosynchronous satellites, such as PAN . A special case of geosynchronous orbit is the geostationary orbit , which is a circular geosynchronous orbit at zero inclination (that is, directly above the ...
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 are mainly of two types: polar orbiting (covering the entire Earth asynchronously) or geostationary (hovering over the same spot on the equator ).
Geostationary satellites are directly overhead at the equator and appear lower in the sky to an observer nearer the poles. As the observer's latitude increases, communication becomes more difficult due to factors such as atmospheric refraction , Earth's thermal emission , line-of-sight obstructions, and signal reflections from the ground or ...
A geostationary equatorial orbit (GEO) is a circular geosynchronous orbit in the plane of the Earth's equator with a radius of approximately 42,164 km (26,199 mi) (measured from the center of the Earth). [21]: 156 A satellite in such an orbit is at an altitude of approximately 35,786 km (22,236 mi) above mean sea level. It maintains the same ...
The Geostationary Operational Environmental Satellite (GOES) program began as a joint effort between the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) in 1975 to develop geostationary weather satellites following the success of the Applications Technology Satellite (ATS) and Synchronous Meteorological Satellite programs ...
The Geostationary Operational Environmental Satellite (GOES) program, which now supports weather forecasting, severe storm tracking, and meteorology research in the United States, followed immediately after the SMS program; the GOES 1 satellite was initially designated SMS-C. [4] SMS-1 and SMS-2; and GOES-1, GOES-2, and GOES-3; were essentially ...
The main objective of these satellites were weather predictions and the study of the environment of space. Significantly, this program focused on launching satellites to orbit geosynchronously and evaluate the effectiveness of this orbit pattern in observing the Earth. [1] ATS-3, the longest-lasting mission, saw a life span of over 20 years. It ...
