Starlink is a satellite internet service developed by SpaceX, designed to deliver high-speed internet anywhere on Earth—even in the most remote locations. As of 2025, Starlink operates over 6,000 low Earth orbit (LEO) satellites, making it the largest satellite constellation in the world.

So, how does it actually work? Unlike traditional internet that relies on cables or cell towers, Starlink sends internet signals from space. Here’s the step-by-step process:

1. User Terminal (Dishy): You install a small satellite dish at your home or location. This dish automatically aligns itself to communicate with the nearest Starlink satellites overhead.
2. LEO Satellites: These satellites orbit about 550 km (342 miles) above the Earth, much closer than older geostationary satellites. That close distance reduces lag (latency), so your internet feels fast and responsive.
3. Ground Stations: The satellites relay data between your dish and ground stations connected to the internet backbone. Essentially, your requests (like loading a webpage) go from your device to the satellite, then to a ground station, and finally out to the internet.

Because Starlink satellites constantly move across the sky, your dish seamlessly switches between satellites to maintain a strong connection.

As of now, Starlink offers speeds around 25–220 Mbps, with latency as low as 25 milliseconds—good enough for streaming, video calls, and online gaming. It also offers Starlink Roam for travelers and Starlink Mobility for vehicles and boats.

Starlink is transforming global connectivity, especially for rural communities and developing regions. With more satellite launches planned, the network will get even faster and more accessible—moving us closer to a world where no place is truly “off the grid.”
