About Starlink Satellite Project

Aspect	Details
Launched	2019
What is Starlink Satellite Project?	It is a SpaceX project aimed at building a broadband network using a cluster of thousands of orbiting satellites.
Purpose	To build a broadband network providing satellite-based internet to the remotest corners of the world.
Method	Deployment of a constellation of low Earth orbit (LEO) satellites.
Altitude	Starlink satellites will be positioned in the altitude range of 350 km to 1,200 km within the LEO, which extends up to 2,000 km above Earth’s surface.

Advantages of Starlink Project

Reduced Latency: Due to the satellites being in LEO, there is a reduced latency between sender and receiver.
Accessibility: Capable of delivering internet to remote areas where traditional methods, like fibre-optic cables, have failed.

Disadvantages of Starlink

Space Debris: The simultaneous launch of thousands of new satellites will significantly increase the load on near-Earth space. Inevitably, some of these satellites will crash, contributing to the space debris population.
Risky Flights: Starlink has often been accused of conducting flights that come dangerously close to other satellites.
Interference with Observations: Astronomers worry that the size and scope of projects like Starlink will interfere with observations of the universe due to the bright, orbiting objects.
Climate Impact: The deorbiting of old satellites will burn a significant amount of metal in the Earth’s atmosphere, which could lead to unpredictability in the planet’s climate.

Comparison with Geostationary Satellite Internet

Advantages of Geostationary Satellites:
- Better Coverage: Fewer satellites (approximately 3 or 4) are needed to cover the entire Earth.
- Stationary Appearance: Satellites appear stationary relative to Earth, simplifying linkage.
Disadvantages of Geostationary Satellites:
- High Latency: Due to their higher placement at 35,786 km above the Earth’s equator, they experience higher latency.

India and Space Internet

Indian Space Policy-2023:
- Allows non-government entities (NGEs) to provide national and international space-based communication services via self-owned, procured, or leased geostationary and non-geostationary satellite orbit systems.
GMPCS License Holders:
- Only two firms have a Global Mobile Personal Communication by Satellite (GMPCS) licence from the Department of Telecommunications:
  - Reliance Jio
  - Bharti Airtel Ltd. in partnership with the United Kingdom government’s OneWeb, which merged with the French firm Eutelsat.
