Satellite Internet

LEO constellations operate at 550 km altitude delivering 12-45 ms latency versus 600+ ms for GEO satellites at 35,786 km. Phased array antennas electronically steer beams to track fast-moving LEO satellites without mechanical parts. Inter-satellite laser links route traffic between satellites in orbit, reducing ground station dependency and improving global coverage. Direct-to-device technology enables standard smartphones to connect to specially designed satellites without modifications. Multi-orbit architectures combine LEO satellites for latency with GEO satellites for coverage continuity.

Rural broadband provides home internet service to areas where terrestrial infrastructure is economically unviable, with Starlink increasingly factored into U.S. BEAD (Broadband Equity, Access, and Deployment) strategies. Aviation connectivity enables passenger Wi-Fi on commercial flights (Air France, SAS deploying Starlink). Maritime connectivity serves shipping, cruise, and offshore operations. Military communications use dedicated satellite networks (MILNET, PLEO) for secure global connectivity. Direct-to-device provides emergency messaging and eventually broadband to standard smartphones in areas without cell towers. Enterprise backup connectivity ensures business continuity when terrestrial connections fail.

The global satellite internet market reached approximately $14.3 billion in 2025 and is projected to grow to $33 billion by 2030 at 15-18% CAGR. Starlink generated approximately $10 billion in revenue in 2025 with $2 billion in free cash flow and 10 million subscribers. The military satellite communications market is expanding rapidly with the PLEO program ceiling at $13 billion. The aviation connectivity segment and maritime connectivity each represent multi-billion-dollar addressable markets.
