Space Internet

SpaceX, a pioneer in space technology, recently sent 60 satellites into Low Earth Orbit for its Starlink Network project. This initiative represents one of the most ambitious endeavors to transmit data signals from space. SpaceX aims to grow this project into a constellation of around 12,000 satellites.

Types of Satellites in Space Internet

Two types of satellites are currently used to establish the satellite internet system. Let’s delve into the specifics of each.

Space Internet Using Geostationary Satellite

The concept of using geostationary satellites for internet services is not new. Most satellite-based internet services currently use Geostationary Satellites, which operate in the geostationary orbit 35,786 km above the Earth’s equatorial surface.

  • Just 3 to 4 geostationary satellites can blanket almost one-third of the Earth, facilitating global internet access.
  • Geostationary satellites, appearing stationary from Earth, make establishing and maintaining connections easier and more reliable.
  • Data transfer via geostationary satellites can feel sluggish due to their high altitude, causing considerable latency of up to 600 milliseconds.
Space Internet Using Satellites in Low Earth Orbit

The Lower Earth Orbit (LEO) is located 2,000 km above the Earth’s sea surface, directly above the equator. The global space internet system using satellites in LEO offers several advantages, including a solution for reducing latency.

  • Satellites in low Earth orbit (LEO) can reduce latency by being closer to the Earth, resulting in a quicker data transmission time of about 20-30 milliseconds, which is crucial for real-time applications.
  • LEO satellites can reach areas that traditional methods might find challenging due to their lower altitude and wider coverage range, enabling them to be effective in remote or difficult-to-access regions.
  • The coverage area of LEO satellites is smaller compared to those in higher orbits, potentially leading to gaps in communication and service availability.
  • To ensure continuous data coverage, a significant number of satellites are necessary in LEO, which escalates costs and poses challenges for space management and research activities.


Despite the individual drawbacks of each type of satellite, space internet offers several benefits to humanity.

  • It promises to provide high-speed internet up to 300Mbps, as stated by Elon Musk for the Starlink project.
  • It has the potential to connect people from remote or rural areas where traditional systems cannot reach.
