Traditional broadband services are unable to reach this area due to geographical constraints. However, by leveraging satellite communication technology, it becomes possible to bridge the digital divide and provide seamless connectivity to such underserved regions.
Satellite orbits play a crucial role in enabling global telecommunications coverage. There are three primary types of orbits utilized by telecommunication satellites:
- Geostationary Orbit (GEO): Satellites in GEO orbit remain fixed relative to Earth’s surface, allowing them to maintain continuous communication with specific geographic areas known as footprints. These satellites are positioned approximately 35,786 kilometers above the equator, providing widespread coverage but also introducing signal latency due to their distance from users.
- Medium Earth Orbit (MEO): MEO satellites operate at lower altitudes than GEO satellites, typically ranging between 8,000 and 20,000 kilometers above Earth’s surface. This orbit offers reduced latency compared to GEO but requires a larger number of satellites strategically placed around the globe for seamless worldwide coverage.
- Low Earth Orbit (LEO): LEO is the closest orbit to Earth among the three mentioned here, usually ranging from a few hundred kilometers up to 2,000 kilometers above the surface. LEO constellations consist of numerous interconnected satellites that work together cooperatively while moving rapidly across the sky overhead. This configuration minimizes signal delay even further but necessitates more complex ground-based infrastructure.
To better understand the advantages and disadvantages of different orbits, let us consider a comparison in table format:
