Direct Impacts on Satellite Operations

Space weather affects satellites in multiplee ways, and each impact impact consists different metigation strategies.

Communication and Navigation

Solar flares cause sudden ionospheric continances that degrassion GPS signals, reducing precision agriculture, aviation, and autonomous systems. High- campetency (HF) communications used b y aviation and maritime can bee blaced out entirely. Forecasting these events allows operators to switch to alternate perpeencies or delay kricaol operations.

Power Systems and Electronics

Energetic particles can cause single-event upsets in memory chips, learing to false commands or data crution. Surface charging from geomagnetic storms can build up static electricity, causing electrostatic discharges that permanently damage accordants. Forecasts of enhanced particle flux enable operators to power down non- essential systems or switch to hardened modes.

Orbital Drag and Re- entry

Geomagnetik storms heat the upper atmosfee, causing it to expand. This increastes drag on satellites in low Earth orbit, shortening their lifetime and making orbit predictions uncertain. Accurate contraming allows operators to adjust orbits or plan fuel- approvent manévrvers. For large constellations like Starlink, drag variations con deloyments or incree collision risks.
