ESA Space Weather Service Network Workshop 2026

Session

Integrating Data for Next-Generation Tools in Satellite Drag Calculation and Collision Avoidance

ESOC

Description

This session examines how new data and updated modelling techniques can improve satellite drag estimation, thermospheric density predictions, and overall orbit forecasting. Using current space-weather data alongside modern analytical methods, as well as state-of-the-art AI forecasting techniques, the discussion focuses on how reducing uncertainty in drag predictions can support more informed operational decisions, ultimately helping to limit unnecessary collision-avoidance manoeuvres and improve reliability in an increasingly crowded space environment.
