Space-environment intelligence firm Mission Space has issued a new risk analysis warning that escalating solar storms present a direct operational threat to global navigation satellite systems (GNSS) and the terrestrial economies that rely on them. Driven by intense solar flares, geomagnetic storms, and coronal mass ejections, heightened space weather activity is creating severe ionospheric perturbations that degrade satellite positioning, navigation, and timing (PNT) accuracy across the globe. The findings project that economic exposures tied directly to GNSS disruptions will reach $3.23 billion in 2026 and surge to $6.46 billion in annualized losses by 2035.
The report emphasizes that space weather causes signal scintillation and dispersion, resulting in reduced signal-to-noise ratios, tracking loss, and positioning errors for receivers on the ground. These radio navigation interruptions threaten safety-critical and high-precision applications, ranging from commercial aviation flight paths and maritime shipping to autonomous agricultural equipment and telecommunications synchronization. Severe solar radio bursts in the L-band spectrum can flood sunlit hemispheres, overwhelming receiver tracking capabilities and causing widespread signal outages.
Beyond direct signal interference, solar activity causes upper-atmosphere expansion, dramatically increasing atmospheric drag on low-Earth orbit (LEO) satellites. This heightened drag alters operational trajectories, forcing constellation operators to deploy thrusters for corrective maneuvers or risk orbital decay and collisions with space debris. For next-generation commercial LEO constellations delivering augmented GNSS and timing services, the combined threat of atmospheric drag and single-event radiation bursts poses a systemic risk to network redundancy.
Mission Space notes that the growing economic risk is driven not by an unprecedented increase in solar activity, but by the rapid expansion of satellite infrastructure and modern society’s heavy reliance on spatial positioning data. The firm urges satellite operators, defense agencies, and commercial GNSS integrators to shift from broad space weather alerts to localized, route-specific risk modeling to safeguard critical assets. Real-time environmental monitoring and predictive analytics will be vital to preserving positioning integrity and preventing compounding economic damage throughout the decade.
