LEO Satellites vs GEO Satellites: Comparison and Advantag

Satellites play a vital role in global communications, navigation, and earth observation. However, not all satellites are created equal; the two main types often discussed are LEO (Low Earth Orbit) satellites and GEO (Geostationary Earth Orbit) satellites. Each has its own characteristics, advantages, and disadvantages that make them suitable for specific applications. This article will compare LEO and GEO satellites and explore the advantages of each.

LEO (Low Earth Orbit) Satellites

Are located at altitudes between 160 and 2,000 kilometers above the earth's surface, Circle the earth every 90 to 120 minutes, Low latency due to their closer proximity to the earth, ideal for applications that require fast response.

Advantages:

LEO satellites offer faster response times compared to GEO satellites, making them ideal for internet applications, voice communications, and online gaming. Because they are closer to the Earth's surface, LEO satellites can produce higher resolution images, making them suitable for Earth observation and reconnaissance. LEO satellites are generally cheaper to launch because they require less energy to reach a lower orbit.

Disadvantages:

LEO satellites have shorter operational lives and require frequent replacement A single LEO satellite can only cover a small area of ​​the Earth at a time, requiring a large constellation for global coverage.

GEO (Geostationary Earth Orbit) Satellites 

Are located at an altitude of about 35,786 kilometers above the Earth's surface, The orbit is synchronous with the Earth's rotation, so they appear to remain in the same position in the sky, Latency is higher due to the greater distance from the Earth.

Advantages:

A single GEO satellite can cover a very large area, up to one-third of the Earth's surface, ideal for television broadcasting, satellite communications, and weather monitoring.

Because they remain in the same position relative to the Earth, GEO satellites are well suited to applications that require consistent coverage, such as satellite television and fixed communications.

GEO satellites typically have longer operational lives, reducing the need for frequent replacement.

Disadvantages:

Slower response time makes it less ideal for applications that require low latency. Launching to GEO orbit is more expensive because it requires more energy to reach higher altitudes.

So the comparison between LEO and GEO satellites has its own advantages and disadvantages. LEO satellites excel in terms of low latency and high image resolution, making them an ideal choice for fast communications and earth observation. On the other hand, GEO satellites offer wide coverage and long operational life, suitable for broadcasting and fixed communications. The choice between LEO and GEO depends on the specific needs of the application and its intended use. By understanding the characteristics of each type of satellite, we can maximize the benefits of satellite technology for various purposes.

Thrive leverages the advantages of each type of satellite to provide optimal communication and internet services for its customers. LEO satellites, with low latency and high resolution, are ideal for applications that require fast connectivity and detailed observation. Meanwhile, GEO satellites offer wide coverage and long-term stability, ideal for broadcasting and fixed communications services. With the combination of using LEO and GEO satellites, Thrive can ensure that all customer needs, both for fast service and wide coverage, can be met properly.
