LEO/MEO 卫星的全球市场(2023-2033)Global LEO and MEO Market 2023-2033 |
LEO(低地球轨道)卫星和 MEO(中地球轨道)卫星是在卫星通讯和其他天基应用中非常重要的两种轨道。
低地球轨道 (LEO) 卫星放置在距离地球表面约 160 公里(100 英里)至约 2,000 公里(1,200 英里)的轨道上。
LEO 卫星通常在 2,000 公里以下的高度运行,并以高速运行,绕地球一圈需要 90 到 120 分钟。
优点:LEO 卫星距离地球更近,因此讯号延迟更低、资料速率更高且覆盖全球。 特别适合需要即时通讯的应用,例如音讯和视讯会议。
低轨卫星的缺点是它们在天空中移动速度很快,因此覆盖范围很短。 需要更大的卫星星座来提供连续覆盖。 此外,低地球轨道卫星网路的设计和操作变得更加复杂,因为当卫星经过不同的地面站时,需要在卫星之间进行无缝切换。
MEO 卫星通常放置在距离地球 2,000 公里至 36,000 公里的轨道上。
MEO 卫星的运作高度高于 LEO 卫星,但低于 GEO(地球静止轨道)卫星。 它以中等速度移动,并在几个小时内完成一个轨道。
MEO卫星位于LEO卫星和GEO卫星之间。 MEO 卫星比 GEO 卫星覆盖范围更广,延迟比 GEO 卫星更低,尤其是在极地地区。 MEO 卫星通常用于 GPS、导航和卫星通讯服务。
MEO 卫星比 GEO 卫星需要更复杂的追踪和定位系统。 由于需要更多卫星来覆盖整个全球,因此营运成本更高。 然而,它们不需要比 GEO 卫星更复杂的地面设备。

LEO (Low Earth Orbit) and MEO (Medium Earth Orbit) satellite orbits are two types of orbits that are important in satellite communication and other space-based applications.
Satellites in low Earth orbit (LEO) are positioned in orbits ranging from about 160 kilometers (100 miles) to about 2,000 kilometers (1,200 miles) above the Earth's surface.
LEO satellites typically operate at altitudes less than 2,000 kilometers and travel at high speeds, completing an orbit around the Earth in 90 to 120 minutes.
Advantages: Because of their proximity to the Earth, LEO satellites have low signal latency, high data rates, and better global coverage. They are especially well-suited for applications requiring real-time communication, such as voice and video conferencing.
One disadvantage of LEO satellites is that they have a shorter coverage window because they move quickly across the sky. To provide continuous coverage, a larger constellation of satellites is required. Furthermore, due to the requirement for seamless handovers between satellites as they pass over different ground stations, the design and operation of LEO satellite networks are more complex.
MEO satellites are typically positioned in orbits ranging from 2,000 kilometers (1,200 miles) to 36,000 kilometers (22,000 miles) above the Earth's surface.
MEO satellites operate at higher altitudes than LEO satellites but lower altitudes than GEO (Geostationary Earth Orbit) satellites. They travel at intermediate speeds and complete an orbit in several hours.
MEO satellites provide a balance between LEO and GEO satellites. They offer better coverage than GEO satellites, particularly in polar regions, and lower latency than GEO satellites. MEO satellites are commonly used for GPS, navigation, and satellite-based communication services.
MEO satellites require more complex tracking and positioning systems than GEO satellites. Their operational costs are higher because they require a greater number of satellites to provide global coverage. They do, however, require less sophisticated ground equipment than GEO satellites.
