geosynchronous
Meaning: Describing an orbit in which a satellite revolves around the Earth at the same rate as the planet rotates, remaining above a fixed longitude.
A geosynchronous orbit has a period of exactly one sidereal day, meaning the satellite returns to the same position relative to the Earth's surface every 24 hours. When the orbit is also equatorial and circular, it is called geostationary — the satellite appears motionless from the ground. This distinction matters in telecommunications and weather monitoring, where continuous coverage of a particular region is essential.
Examples
- The broadcasting company launched a new geosynchronous satellite to improve signal coverage across northern Europe. 该放送公司发射了一颗新的地球同步卫星,以改善北欧地区的信号覆盖。La empresa de radiodifusión lanzó un nuevo satélite geosincrónico para mejorar la cobertura de señal en el norte de Europa.その放送会社は北ヨーロッパ全域の電波受信を改善するため、新たな地球同期衛星を打ち上げた。방송사는 북유럽 전역의 신호 수신을 개선하기 위해 새로운 지구동기 위성을 발사했다.
- Geosynchronous orbits are particularly valued for meteorological observation because they provide a constant view of weather patterns over a fixed area. 地球同步轨道在气象观测方面尤其受重视,因为它能对固定区域的天气模式提供持续监视。Las órbitas geosincrónicas son especialmente valoradas para la observación meteorológica porque ofrecen una vista constante de los patrones climáticos sobre un área fija.地球同期軌道は、固定された地域の気象パターンを常時監視できるため、気象観測に特に重宝されています。지구동기 궤도는 고정된 지역의 기상 패턴을 지속적으로 관측할 수 있어 기상 관측에 특히 유용하다.
- The Ministry of Defence reviewed proposals for a geosynchronous communications platform to serve overseas operations. 国防部审查了建设地球同步通信平台以服务海外行动的提案。El Ministerio de Defensa examinó propuestas para una plataforma de comunicaciones geosincrónica destinada a operaciones en el extranjero.国防省は海外作戦を支援するための地球同期通信プラットフォームの提案を検討した。국방부는 해외 작전을 지원하기 위한 지구동기 통신 플랫폼 제안을 검토했다.
