Not Your Grandfather's Satellite
Forget the massive, solitary satellites of the past, parked in a fixed geostationary orbit (GEO) 36,000 kilometres away. The new players are small satellites, often no bigger than a pizza box or a washing machine, operating in vast, interconnected groups
called constellations. These fly in Low Earth Orbit (LEO), just a few hundred to 2,000 kilometres up. This proximity is the game-changer. While thousands of these smallsats are needed to provide continuous global coverage, their mass-produced nature and lower launch costs are making space accessible than ever.
The End of Lag
The single most important advantage of LEO satellites is the dramatic reduction in latency—the frustrating delay between sending a signal and getting a response. Traditional GEO satellites have a noticeable lag of 600 milliseconds or more, making real-time applications like video calls or online gaming nearly impossible. Because LEO satellites are so much closer, they can slash that latency to between 20 and 50 milliseconds, a level comparable to terrestrial fibre-optic networks. This leap in performance unlocks the ability to deliver true broadband service to anywhere on the planet.
A New Space Race
This technological shift has ignited a commercial space race. SpaceX's Starlink already operates thousands of satellites, with plans for tens of thousands more. It faces stiff competition from Eutelsat OneWeb, which is partially backed by India's Bharti Global, and Amazon's ambitious Project Kuiper. These companies aren't just launching satellites; they are building vertically integrated ecosystems of hardware, ground stations, and user terminals. Their goal is to capture a slice of a market that serves everyone from individual rural households to airlines, shipping companies, and governments.
Connecting the Unconnected in India
In a nation like India, where nearly half the population still lacks internet access, the potential is enormous. Laying fibre to every remote village in the Himalayas or deserts of Rajasthan is economically and logistically challenging. Small satellite constellations bypass these terrestrial hurdles entirely, offering a lifeline of connectivity. This could revolutionise access to education, telemedicine, and economic opportunities, directly supporting initiatives like Digital India and providing a crucial communication backbone during natural disasters when ground infrastructure fails.
Growing Pains in Orbit
However, this rapid expansion is not without serious challenges. The sheer number of planned satellites—potentially over 100,000—is dramatically increasing the risk of collisions and adding to the growing problem of space debris. A single collision could create a cloud of shrapnel that threatens other satellites. Furthermore, astronomers are concerned about the light pollution from these constellations, as the streaks of satellites can interfere with observations of the universe. Regulators and nations are now grappling with how to manage traffic in an increasingly crowded orbital environment and ensure the long-term sustainability of space activities.
