Orby TV was an American direct broadcast satellite provider based in Burbank, California.Founded in 2019, Orby transmitted digital satellite television and audio to households within the United States and territories on Pan-American satellite Eutelsat 117 West A.
Atmospheric drag at orbital altitude is caused by frequent collisions of gas molecules with the satellite. It is the major cause of orbital decay for satellites in low Earth orbit. It results in the reduction in the altitude of a satellite's orbit. For the case of Earth, atmospheric drag resulting in satellite re-entry can be described by the ...
In addition, satellites in HEO can provide a continuous coverage of the Earth's surface, making it very useful for communication and navigation purposes. [7] A variety of satellites, such as TESS, [8] have been placed in HEO. There are four main reasons that most satellite are placed in lower orbits. First, a HEO can take a month or more per orbit.
Starlink is a satellite internet constellation operated by Starlink Services, LLC, an international telecommunications provider that is a wholly owned subsidiary of American aerospace company SpaceX, [5] providing coverage to over 100 countries and territories.
Orbital's primary products were satellites and launch vehicles, including low Earth orbit (LEO), geosynchronous Earth orbit and planetary spacecraft for communications, remote sensing, scientific and defense missions; ground- and air-launched launch vehicles that delivered satellites into orbit; missile defense systems that were used as ...
The program never put anything into orbit, [5] and it is unrelated to the Black Knight satellite legend. [4] In February 1960, Time reported that the U.S. Navy had detected a dark object thought to be a Soviet spy satellite in orbit. A follow-up article confirmed that the object was "the remains of an Air Force Discoverer 8 satellite that had ...
The Envisat satellite is a large, inactive satellite with a mass of 8,211 kg (18,102 lb) that orbits at 785 km (488 mi), an altitude where the debris environment is the greatest—two catalogued objects can be expected to pass within about 200 m (660 ft) of Envisat every year [40] —and likely to increase. Don Kessler predicted in 2012 that it ...
Strictly speaking, a satellite collision is when two satellites collide while in orbit around a third, much larger body, such as a planet or moon. This definition is typically loosely extended to include collisions between sub-orbital or escape-velocity objects with an object in orbit.
