Space weather event
Definition of a space weather event
A space weather event refers to occurrences resulting from disturbances in the space environment, primarily due to activity from the Sun. These events encompass a variety of phenomena such as solar flares, coronal mass ejections (CMEs), high-speed solar wind, and solar energetic particles. Space weather events can influence the Earth's magnetosphere, ionosphere, and thermosphere. They have the potential to disrupt satellite communications and navigation systems, affect power grids on Earth, and pose radiation risks to astronauts and high-altitude flight crews. Understanding, predicting, and mitigating the effects of space weather is vital for ensuring the safety and efficacy of space operations and terrestrial technologies that rely on space-based systems.
Operational impacts on near-earth space and LEO satellites
Space weather events can rapidly change the near Earth environment, impacting satellite availability and safety. Increased atmospheric density during geomagnetic storms raises drag in LEO, accelerating orbital decay, increasing tracking uncertainty, and complicating conjunction assessment and maneuver planning. They can also degrade radio links and GNSS performance, which affects telemetry, navigation, timing, and coordinated operations across fleets and ground segments.
Look Up support for space weather-driven uncertainty
Look Up supports operators during space weather driven degradation by detecting, tracking, and characterizing LEO objects with its SORASYS radar network, helping maintain an up to date space picture as orbits evolve. Through SYNAPSE, Look Up can fuse multi source SSA data with external information to update catalogues, issue timely alerts, and improve collision avoidance workflows. These capabilities help protect assets and sustain scalable operations when environmental conditions increase uncertainty.
We deliver space situational awareness (SSA) and space domain awareness (SDA) solutions that help secure active satellites and ensure safe operations in the ever-growing expanse of space.
