Applications Technology Satellites
The Applications Technology Satellites (ATS) were a series of experimental satellites launched by NASA, under the supervision of, among others, Wernher von Braun. The program was launched in 1966 to test the feasibility of placing a satellite into geosynchronous orbit. The satellites were primarily designed to act as communication satellites, but also carried equipment related to meteorology and navigation. ATS-6 was the world's first educational satellite as well as world's first experimental Direct Broadcast Satellite (DBS) as part of the Satellite Instructional Television Experiment (SITE) between NASA and ISRO.

Synchronous Meteorological Satellite
The Synchronous Meteorological Satellite (SMS) program, was a program where NASA developed two weather satellites; which were placed into geosynchronous orbit. History SMS-1 was launched May 17, 1974 and SMS-2 was launched February 6, 1975. Both satellites were carried to orbit by Delta 2914 rockets. The program was initiated after the successes achieved by the Applications Technology Satellite (ATS) research satellites, which demonstrated the feasibility of using satellites in geosynchronous orbit for meteorology. 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. SMS-1 and SMS-2; and GOES-1 GOES-1, designated GOES-A and SMS-C prior to entering service, was a weather satellite, developed by the NASA, operated by the United States National Oceanic and ...

Geostationary Operational Environmental Satellite
The Geostationary Operational Environmental Satellite (GOES), operated by the United States' National Oceanic and Atmospheric Administration (NOAA)'s National Environmental Satellite, Data, and Information Service division, supports weather forecasting, severe storm tracking, and meteorology research. Spacecraft and ground-based elements of the system work together to provide a continuous stream of environmental data. The National Weather Service (NWS) and the Meteorological Service of Canada use the GOES system for their North American weather monitoring and forecasting operations, and scientific researchers use the data to better understand land, atmosphere, ocean, and climate dynamics. The GOES system uses geosynchronous equatorial satellites that, since the launch of SMS-1 in 1974, have been a basic element of U.S. weather monitoring and forecasting. The procurement, design, and manufacture of GOES satellites is overseen by NASA. NOAA is the official provider of both G ...

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
ATS-4
ATS-4 (Applications Technology Satellite) also known as ATS-D was a communications satellite launched by NASA on August 10, 1968 from Cape Canaveral through an Atlas-Centaur (AC-17) rocket. Objectives The objective of ATS-4 was to investigate the possibilities of a gravity gradient stabilization system (the method of stabilizing artificial satellites). Features The satellite has a cylindrical shape with a diameter and height (about considering the motor cover) with the surface covered by solar panels that generated a maximum of 350 W of power, and stabilized by gravity gradient. It was based on the Hughes Aircraft HS-306 bus. Instruments A total of four experiments were conducted during the mission: * Microwave Transponder * Gravity Gradient Stabilization * Image Orthicon (Day/Night) Camera * Ion Thruster Mission The Atlas and Centaur stages performed satisfactorily and placed the Centaur/ATS-4 in an elliptical parking orbit. However the Centaur stage failed to re-ignit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
ATS-3
Applications Technology Satellite 3, or ATS-3, was a long-lived American experimental geostationary weather and communications satellite, operated by NASA from 1967 to 2001. It was at one time reputed to be the oldest satellite still in operation. , NASA referred to the ATS-3 as "The oldest active communications satellite by a wide margin." On November 10, 1967, ATS-3 took NASA's first color photo (digital image mosaic) of the full-disk Earth, which was subsequently used on the cover of the first ''Whole Earth Catalog''. History Launched in November 1967, the ATS-3 was in service for 11 years before finally being decommissioned in 1978 along with ATS-1. Among its widest-known achievements are the first full-disk, "true color" composite Earth image (DODGE took color-filtered black-and-white images, put together they produced the very first color image of the full-disk). Its imaging capability has served during disaster situations, from the Mexico earthquake to the Mount St. Hele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
ATS-1
ATS-1 (Applications Technology Satellite 1), also designated ATS-B or Advanced Tech. Sat. 1, was an experimental geostationary satellite, launched in 1966, and part of the Applications Technology Satellites Program. Though intended as a communications satellite rather than as a weather satellite, it carried the Spin Scan Cloud Camera developed by Verner E. Suomi and Robert Parent at the University of Wisconsin. After entering an orbit at above Earth, initially in orbit over Ecuador, it transmitted weather images from the Western Hemisphere, as well as other data, to ground stations, including well as video feeds for television broadcasting. It took one of the first pictures of the Earth's full-disk (the first from a geostationary orbit), on December 11, 1966. "For the first time," historians would note later, "rapid-imaging of nearly an entire hemisphere was possible. We could watch, fascinated, as storm systems developed and moved and were captured in a time series of im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Satellite Instructional Television Experiment
Satellite Instructional Television Experiment or SITE was an experimental satellite communications project launched in India in 1975, designed jointly by NASA and the ISRO, Indian Space Research Organization (ISRO). The project made available informational television programs to rural India. The main objectives of the experiment were to educate the financially backward and academically illiterate people of India on various issues via satellite broadcasting, and also to help India gain technical experience in the field of satellite communications. The experiment ran for one year from 1 August 1975 to 31 July 1976, covering more than 2400 villages in 20 districts of six States and union territories of India, Indian states and territories (Andhra Pradesh, Bihar, Karnataka, Madhya Pradesh, Orissa, Rajasthan). The television programs were produced by All India Radio and broadcast by NASA's ATS-6 (ATS-F) satellite stationed above India for the duration of the project. The project was su ...
