SATELLITE INTERNET | UPSC EXAM

INTRODUCTION

  • On October 7, 2021, SpaceX CEO Elon Musk said that the SpaceX satellite internet service ‘Starlink’ will be available across the United States by the end of the month.
  • Satellite internet is a type of wireless internet that is sent from orbiting satellites. It’s similar to how satellite TVs work. A satellite dish will need to be placed in the user’s home.
  • Satellite internet will be much different from land-based internet services like DSL or cable, which use wires to transport data. Satellite internet will not require any cables since it will be delivered straight from orbit via satellites.

 

WORKING OF SATELLITE – 

  • Radio waves are used to communicate between satellites circling the Earth. A communication network delivers and receives data from a user’s internet-enabled device, through a modem and satellite dish to a satellite in orbit, and then back to Earth to network operations centres (NOC).
  • To provide data to devices, the data goes back via the network, out to space, and back to the land-based satellite dish. Lasers are used to offer satellite internet connectivity by Elon Musk’s Starlink satellites.
  • The user would call to use satellite internet, you’ll need an internet-enabled device, a modem/router, and a satellite dish.

 

HOW SATELLITE INTERNET WILL TRANSFORM THE WORLD – 

  • The satellite internet service will link those living in the world’s most remote locations where normal internet is unavailable.
  • In addition, satellite internet is projected to be speedier than traditional internet. The typical internet speed is presently between 10 and 40 megabits per second, with Musk’s Starlink network promising speeds of up to 300 megabits per second.
  • Satellite internet service might be affected by the weather. A satellite signal can be disrupted by heavy rain, high-speed wind, or a storm.
