Difference
Low Earth Orbit (LEO) Satellites: LEO satellites orbit at an altitude of 2,000 km or less above the earth's surface. They are used for a variety of purposes, including earth observation, communication, and navigation. LEO satellites have a shorter life span than GEO satellites because they are subject to more atmospheric drag, which causes them to lose altitude and eventually fall back to earth. However, LEO satellites have some advantages over GEO satellites. They provide lower latency and higher bandwidth, which make them ideal for applications such as internet and mobile communication. Some examples of LEO satellite constellations include Starlink by SpaceX, OneWeb, and Amazon's Project Kuiper.
Medium Earth orbit (MEO) Satellites: Medium Earth orbit (MEO) satellites are a type of satellite that orbits the Earth at an altitude between 2,000 km and 36,000 km. This is a higher altitude than LEO satellites, but lower than GEO satellites. MEO satellites are primarily used for navigation systems such as GPS, GLONASS, and Galileo. These navigation systems use a network of MEO satellites to provide accurate positioning and timing information to users on the ground. MEO satellites have advantages over both LEO and GEO satellites, including better coverage and more accurate positioning. However, they also have some disadvantages, including higher latency and lower bandwidth than LEO satellites, and lower coverage than GEO satellites. Overall, MEO satellites are an important component of modern navigation systems, and they play a crucial role in many aspects of daily life, including transportation, logistics, and emergency services.
Geostationary Orbit (GEO) Satellites: GEO satellites orbit at an altitude of 36,000 km above the earth's surface. They are used primarily for communication and broadcast services. Because they orbit at the same speed as the earth's rotation, they appear to be stationary in the sky, which makes them ideal for satellite TV and radio services. GEO satellites have a longer life span than LEO satellites, but they also have some drawbacks. They provide higher latency and lower bandwidth, which can make them unsuitable for applications that require real-time communication. Some examples of GEO satellite operators include SES, Intelsat, and Eutelsat.
LEO and GEO satellites have different advantages and disadvantages, which make them suitable for different applications. LEO satellites are better suited for applications that require low latency and high bandwidth, while GEO satellites are better suited for applications that require high coverage and stable communication. Understanding the differences between LEO and GEO satellites is important for professionals in the satellite industry to design, develop, and operate satellite systems that meet the needs of their customers.
