A celestial body that orbits around a planet, such as the Moon's orbit around Earth, typically smaller in size compared to the planet it accompanies.
An entity or system that exists in a subordinate relationship surrounding and supporting a central figure or structure, often used in contexts such as satellite nations or cities that depend on a larger metropolitan area.
A man-made object launched into space that revolves around Earth or another celestial body, designed for functions like communication, observation, or research.
A communication system that utilizes artificial satellites as relay points to facilitate wireless communication over long distances.
A broadcasting method where signals from a ground station are received by a satellite in geostationary orbit, amplified, and then transmitted to viewers.
Example:
衛星は今軌道に乗っている。
A method of transmitting television and radio signals directly to viewers using satellites positioned in geostationary orbit, which receive signals from ground stations and amplify them for distribution.
A technology designed to provide high-quality broadcasting services, especially to areas with poor reception, enabling access to a wide range of channels and programming.
An innovative broadcasting technique that relies on artificial satellites to facilitate communication and entertainment distribution, launched to enhance media accessibility since its inception in 1989.
An artificial object that is launched into space, primarily to orbit the Earth for purposes such as weather monitoring, scientific research, or telecommunications.
A spacecraft intentionally placed into orbit around Earth by humans to gather data, relay communications, or facilitate navigation and other functions.
A technology-driven entity created by humans and deployed into space, designed to perform various tasks while revolving around the Earth.
Example:
現在では我々が作った人工衛星が地球の周辺を回転している。
An artificial satellite positioned in a geostationary orbit approximately 36,000 kilometers above the equator, appearing to remain fixed in a specific location relative to the Earth's surface due to its synchronized rotation with the planet's own spin.
A satellite designed to maintain a constant position relative to a particular point on the Earth, allowing for uninterrupted communication and meteorological observation by orbiting in alignment with the Earth’s rotational speed.
A specialized satellite that revolves around the Earth in such a way that it completes one orbit in the same time it takes for the Earth to rotate once, thereby providing a constant line of sight for data transmission and monitoring purposes.
An artificial satellite designed to facilitate long-distance communication by relaying signals between ground stations, often utilized in broadcasting services.
A specific type of satellite that employs transponders to collect and send information over vast distances, supporting various communication technologies including television and radio transmission.
A satellite that operates in space, serving as a relay point to enable the exchange of data, voice, and video signals across large geographical areas.
