Satellite services for aviation
Commercial aviation is a major consumer of satellite services across multiple categories: navigation (GPS/Galileo for flight management systems and precision approach), surveillance (ADS-B global tracking via Iridium-hosted Aireon), weather data (satellite-derived meteorological products), and connectivity (in-flight internet for passengers and crew). The aviation satellite market is growing rapidly, particularly in in-flight connectivity (IFC) as airlines invest to meet passenger expectations for fast internet at altitude.
In-flight connectivity market
The global IFC market exceeded $6 billion in 2024, with over 10,000 commercial aircraft equipped. Market leaders include Panasonic Avionics, Viasat/Inmarsat (following the 2023 merger), and emerging LEO providers including Starlink (with airline contracts including Air France, Delta, Japan Airlines, and United). Ka-band HTS GEO remains the incumbent technology, but Starlink's aeronautical service offers 100+ Mbps per aircraft vs. 5–30 Mbps typical for GEO Ka-band — a transformative difference enabling streaming-quality content for every passenger simultaneously.
Safety and navigation
Aviation satellite navigation is distinct from consumer GPS: aircraft flight management systems (FMS) use certified GNSS receivers with RAIM (Receiver Autonomous Integrity Monitoring) algorithms that detect signal anomalies. The FAA's WAAS (Wide Area Augmentation System) and EASA's EGNOS provide SBAS-enhanced accuracy enabling precision approaches (LPV — Localizer Performance with Vertical guidance) at airports without ILS equipment. Global ADS-B mandate completion (2020 in Europe and US) combined with the Aireon space-based ADS-B receiver network on Iridium NEXT has eliminated 'black holes' in oceanic airspace where radar coverage was absent — enabling more efficient oceanic routing and reducing required separation minima.
