Starlink is a satellite network launched by SpaceX into Earth's orbit, providing internet service to people worldwide. The Starlink satellite constellation currently consists of over 5,250 operational spacecraft. However, six satellites launched on January 2 are the first to have direct connectivity to smartphones.
What does Starlink do?
Starlink is a satellite internet constellation built by the American satellite company SpaceX to provide satellite internet access.
Where are Starlink satellites currently located?
While traditional satellites transmitting TV signals operate in a high orbit called geostationary orbit, approximately 35,000 kilometers above the Earth, Starlink internet satellites are in a much lower orbit, about 550 kilometers above Earth, known as low Earth orbit (LEO).
How many Starlink satellites are there?
There are approximately 5,400 operational spacecraft in the Starlink satellite constellation in Earth's orbit, and this number continues to increase. The company aims to launch 144 more missions in 2024.
Where do Starlink satellites get their power from?
Each Starlink satellite, with a mass of 260 kg, is equipped with four powerful antennas and a solar panel for power generation. They use krypton as fuel for ion thrusters. Starlink satellites also have an autonomous system to maneuver and avoid collisions with other spacecraft.
How does the Starlink system work?
Starlink's internet modem functions like other modems in your home but sends and receives data via satellite signals. Additionally, you can connect the modem to your home network or Wi-Fi router to share internet access. Starlink provides numerous advantages, especially for people living in remote areas.
How fast do Starlink satellites travel?
Starlink satellites travel at a high speed of around 27,000 kilometers per hour. Due to this high speed, a receiver terminal can only stay in the satellite's signal for up to 4 minutes, requiring it to switch to the next satellite in line.
