OneWeb Constellation Fleet Data

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.

Schema

Column	Type	Description	Sample	Null %
date	datetime64[ns]	UTC date of the daily snapshot; one row per inclination plane per date	2026-04-15 00:00:00	0.0%
inclination_plane	float64	Rounded inclination in degrees; OneWeb Gen1 uses ~87.9 deg polar planes	87.0	0.0%
total_count	int64	Total OneWeb objects in this inclination plane tracked on this date	2	0.0%
operational_count	int64	Satellites within 50 km of the 1,200 km operational altitude	1	0.0%
raising_count	int64	Satellites below operational altitude climbing toward target	1	0.0%
deorbiting_count	int64	Satellites below 600 km with positive mean_motion_dot (controlled deorbit)	0	0.0%
mean_altitude_km	float64	Mean altitude in this inclination plane, kilometres above Earth's surface	853.48	0.0%

Quick stats

• 651 OneWeb satellites tracked across 3 inclination planes
• 648 operational, 3 raising, 0 deorbiting
• 18 daily snapshot rows (2026-04-15 to 2026-04-20)
• Third point of comparison for juliensimon/starlink-fleet-data vs juliensimon/kuiper-fleet-data

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/oneweb-fleet-data", split="train")
df = ds.to_pandas()

from datasets import load_dataset

ow = load_dataset("juliensimon/oneweb-fleet-data", split="train").to_pandas()
sx = load_dataset("juliensimon/starlink-fleet-data", "daily_snapshots", split="train").to_pandas()
ku = load_dataset("juliensimon/kuiper-fleet-data", split="train").to_pandas()

# LEO broadband race: operational satellites over time
ow_ops = ow.groupby("date")["operational_count"].sum().rename("oneweb")
sx_ops = sx.groupby("date")["operational_count"].sum().rename("starlink")
ku_ops = ku.groupby("date")["operational_count"].sum().rename("kuiper")
print(ow_ops.to_frame().join([sx_ops, ku_ops], how="outer").tail(10))
