Dataset description

Daily health snapshots of the OneWeb (Eutelsat OneWeb) satellite constellation, derived from CelesTrak GP (General Perturbations) data. Tracks satellite count and lifecycle status across OneWeb's near-polar orbital planes.

OneWeb operates a ~650-satellite first-generation LEO broadband constellation at roughly 1,200 km altitude and 87.9 degrees inclination. Unlike Starlink's lower 550 km shells, OneWeb's higher orbit yields larger per-satellite footprints and longer orbital lifetimes, at the cost of higher latency and fewer satellites needed for global coverage. The company merged with Eutelsat in 2023 to become Eutelsat OneWeb, creating a combined GEO plus LEO operator that targets enterprise and government customers rather than direct-to-consumer broadband.

This dataset is designed as the third point of comparison alongside juliensimon/starlink-fleet-data and juliensimon/kuiper-fleet-data. Without OneWeb in the picture, a head-to-head chart of the LEO broadband race is misleading — OneWeb completed its Gen1 deployment before Kuiper started and remains the second-largest operational LEO broadband constellation after Starlink. Status is inferred from orbital mechanics alone, bucketed by inclination plane.

This dataset is suitable for time-series forecasting, tabular classification tasks.
