Starlink Ephemeris Data Enable First Real-World Tomographic Map of Thermospheric Density
Researchers at Kyoto University have demonstrated a new way to observe Earth’s upper atmosphere by transforming publicly available Starlink orbital data into the first tomographic map of thermospheric density derived from real satellite measurements rather than simulations. The study, published in *Earth, Planets and Space*, used orbital ephemeris data from approximately 1,200 Starlink satellites operating…
