Dataset description

Daily health snapshots of Amazon's Project Kuiper broadband constellation, derived from CelesTrak GP (General Perturbations) data. Tracks satellite count, orbital shell, and lifecycle status across the three FCC-authorized Kuiper shells.

Project Kuiper is Amazon's answer to SpaceX Starlink: a low-Earth-orbit broadband constellation of 3,236 satellites authorized by the FCC to deliver internet service globally via the Leo network integrated with Amazon Web Services. Kuiper launched its first production satellites in 2025 and is ramping deployment on Atlas V, Vulcan, Falcon 9, and New Glenn rockets. The constellation operates in three inclination shells at altitudes between 590 km and 630 km, each hosting multiple orbital planes.

This dataset mirrors the schema of the companion juliensimon/starlink-fleet-data dataset, enabling direct side-by-side comparison of the two largest commercial LEO broadband constellations. Status is inferred from orbital mechanics alone: satellites within 20 km of their shell's target altitude are classified operational; those below are raising or deorbiting depending on mean motion derivative.

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 shell per date	2026-04-15 00:00:00	0.0%
shell_id	int64	Integer shell identifier (0-2); 0=33 deg, 1=42 deg, 2=51.9 deg	2	0.0%
shell_name	str	Human-readable shell label encoding inclination and target altitude	Shell 3 (51.9 deg / 630km)	0.0%
total_count	int64	Total Kuiper objects tracked in this shell on this date, all statuses	239	0.0%
operational_count	int64	Satellites within 20 km of the shell's target altitude	164	0.0%
raising_count	int64	Satellites climbing toward target altitude (below target, stable or ascending)	75	0.0%
deorbiting_count	int64	Satellites below 350 km with positive mean_motion_dot (controlled deorbit)	0	0.0%
mean_altitude_km	float64	Mean altitude of satellites in this shell, kilometres above Earth's surface	586.21	0.0%

Quick stats

• 299 Kuiper satellites tracked
• 175 operational, 122 raising, 2 deorbiting
• 26 daily snapshot rows (2026-04-15 to 2026-05-10)
• Companion to juliensimon/starlink-fleet-data for head-to-head LEO broadband analysis

Usage

from datasets import load_dataset

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

from datasets import load_dataset

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

# Head-to-head operational growth
k = kuiper.groupby("date")["operational_count"].sum().rename("kuiper")
s = starlink.groupby("date")["operational_count"].sum().rename("starlink")
print(k.join(s, how="outer").tail(10))
