However, it also means that each satellite covers a smaller area, necessitating a large constellation to provide global coverage.

The Starlink Satellite Constellation Explained

The Starlink constellation is designed to provide continuous, global coverage. The satellites are arranged in multiple orbital planes, ensuring that at least one satellite is always within line of sight of any given point on Earth. The constellation operates in a mesh network, with satellites communicating with each other via laser links. This allows data to be routed through the network efficiently, reducing the need for ground-based infrastructure.

Ground Stations and User Terminals: Connecting the Dots

Ground stations, also known as gateways, are critical components of the Starlink network. These stations connect the satellite constellation to the terrestrial internet backbone. User terminals, often referred to as “Starlink dishes,” are installed at the customer’s location to communicate with the satellites. These terminals are equipped with phased-array antennas, which can electronically steer the beam to maintain a connection with the satellites as they move across the sky.

The Role of Phased-Array Antennas and Laser Links

Phased-array antennas are a key innovation in Starlink’s technology. Unlike traditional parabolic antennas, which require mechanical movement to track satellites, phased-array antennas can electronically steer the beam, allowing for rapid and precise adjustments. This ensures a stable connection even as satellites move at high speeds across the sky. Additionally, Starlink satellites use laser links to communicate with each other, enabling data to be transmitted across the constellation without needing to relay through ground stations. This reduces latency and increases the overall efficiency of the network.
