全球通讯卫星市场(2023-2033)Global Communication Satellite Market 2023-2033 |
通讯卫星覆盖广阔的地理区域,有时覆盖各大洲或整个全球。 通讯卫星透过在地面通讯站之间中继讯号来促进世界不同地区之间的连接和通讯。 通讯卫星可以根据其预期用途和覆盖范围要求放置在不同的轨道上。 地球静止轨道 (GEO) 卫星位于地球赤道上方 35,786 公里处,相对于地球自转是固定的。 这允许连续覆盖特定区域。 另一方面,低地球轨道(LEO)卫星的轨道高度在距离地球数百至数千公里的范围内。
LEO卫星具有低延迟和高资料传输速度等优势,但需要更多卫星才能覆盖整个地球。
转发器内建于通讯卫星中,用于接收来自一个位置的讯号并将其重新传输到另一个位置。 转发器放大接收到的讯号,改变其频率或波长,然后将其重新传回地球。 卫星转发器设计用于处理不同的频率,并且可以同时支援多个频道。 通讯卫星在不同的频段运行,具体取决于应用和监管考虑。 不同的频段(例如 C 频段、Ku 频段和 Ka 频段)被指定用于特定用途。 每个频段都有自己的优点和缺点,包括讯号传播、频宽容量和监管限制。
语音通话、电视广播、网路连线、行动通讯、视讯会议、企业资料传输和遥感皆由通讯卫星支援。 通讯卫星在连接世界各地的人们、企业和社区方面发挥着至关重要的作用,实现远距离无缝通讯。
本报告分析了全球通讯卫星市场,并探讨了整体市场规模的前景、按地区和国家划分的详细趋势、关键技术概述以及市场机会。
Communication satellites cover vast geographical areas, frequently spanning continents or even the entire globe. They facilitate global connectivity and communication between different regions of the world by relaying signals between ground-based communication stations. Depending on their intended applications and coverage requirements, communication satellites can be placed in various orbits. Geostationary Earth Orbit (GEO) satellites are 35,786 kilometers above the Earth's equator and remain fixed about the Earth's rotation. This enables them to provide continuous coverage over a specific geographic area. Low Earth Orbit (LEO) satellites, on the other hand, orbit at altitudes ranging from a few hundred to a few thousand kilometers from the Earth.
LEO satellites have advantages such as lower latency and higher data transfer rates, but providing global coverage requires a larger number of satellites.
Transponders are built into communication satellites to receive signals from one location and retransmit them to another. Transponders receive incoming signals, amplify them, and alter their frequency or wavelength before retransmitting them to Earth. The satellite's transponders are designed to handle different frequencies and can accommodate multiple channels at the same time. Depending on the intended applications and regulatory considerations, communication satellites operate in a variety of frequency bands. Different frequency bands, such as C-band, Ku-band, and Ka-band, are designated for specific purposes. Each frequency band has its own set of advantages and disadvantages in terms of signal propagation, bandwidth capacity, and regulatory constraints.
Voice calls, television broadcasting, internet connectivity, mobile communications, video conferencing, data transmission for businesses, and remote sensing are all supported by communication satellites. They play an important role in connecting people, businesses, and communities around the world, allowing for seamless communication across vast distances.
