Amazon Leo Satellite Tracker
Explore Amazon Leo (Project Kuiper) satellites using current operator-derived orbital data.
How to use this tracker
Amazon Leo was previously known as Project Kuiper. Positions are calculated from CelesTrak supplemental orbital elements.
Amazon Leo is the permanent name adopted in November 2025 for the satellite broadband program previously known as Project Kuiper. The tracker above uses public orbital elements to calculate where catalogued Amazon Leo spacecraft are now and how they relate to your local horizon.
What Amazon Leo is
Amazon Leo is a low-Earth-orbit satellite broadband network intended to extend high-speed connectivity to places where terrestrial networks are limited or difficult to build. Amazon developed the program for years under the Project Kuiper code name and adopted Amazon Leo as the permanent identity on November 13, 2025.
The constellation includes many spacecraft launched across multiple missions. The number catalogued in public orbital datasets can change as launches occur, objects receive identifiers and operational states evolve.
What the live tracker is actually calculating
The map and local-sky values are calculated from public orbital elements. SGP4 propagation estimates each spacecraft’s position at the requested time, then the page converts that position into Earth coordinates and, when you provide a location, observer-relative azimuth and elevation.
This is not Amazon’s internal command-and-control telemetry. The page should therefore be read as an independent public-orbit visualization, with source freshness displayed in the tool.
Can Amazon Leo satellites be seen from the ground?
Some low-orbit satellites can become optically visible when they reflect sunlight, but geometric position alone is not a brightness prediction. Visibility depends on sunlight, range, spacecraft attitude, atmospheric transparency and local light pollution. A satellite shown above your horizon may still be too faint to see.
For a broader naked-eye pass search, use the Satellites Above Me tool, which applies additional viewing checks across a curated bright-object catalog.
Why orbital data change
LEO spacecraft can perform orbit raising, station keeping and collision-avoidance manoeuvres. New tracking observations also improve element sets. Rechecking the tracker near the time of interest is more reliable than treating an old screenshot as a permanent trajectory.
Official context and orbit source
Amazon’s official overview confirms that Project Kuiper was renamed Amazon Leo. Public orbital elements used for independent tracking are obtained through CelesTrak. TagBuilder Space does not claim access to Amazon’s private spacecraft telemetry.
Frequently asked questions
Is Amazon Leo the same project as Project Kuiper?
Yes. Amazon retired the Project Kuiper code name and adopted Amazon Leo as the permanent identity in November 2025.
Are the positions direct from Amazon telemetry?
No. They are independently calculated from public orbital elements.
Why might the satellite count change?
New launches, catalog updates and operational changes can alter which spacecraft appear in public datasets.
Does “above my horizon” mean I can see it?
No. Optical visibility also depends on illumination, brightness, weather and local sky conditions.
How to use the Amazon Leo satellite tracker
Amazon Leo is the permanent name for the satellite-broadband program previously developed as Project Kuiper. The tracker above follows catalogued spacecraft using public orbital information. Select your location to convert the calculated Earth-centered orbit into local azimuth and elevation, or use the wider map view to understand how the constellation is distributed around Earth.
The points shown here are independent public-orbit calculations. They are not a private Amazon command-and-control feed, and the number of catalogued spacecraft can change as new launches occur, objects receive identifiers and satellites maneuver into operational or disposal orbits.
Why a low-Earth-orbit broadband constellation uses many satellites
Low Earth orbit places spacecraft much closer to users than traditional geostationary communications satellites. That shorter range can reduce signal travel time, but a single LEO satellite moves across the sky rather than remaining fixed over one longitude. Large constellations therefore use many spacecraft and hand connections between satellites as coverage geometry changes.
Amazon's official company material explains the program and its transition from the Project Kuiper name to Amazon Leo. This page focuses only on independently trackable public orbital data.
Can Amazon Leo satellites be seen from the ground?
Some low-orbit satellites can reflect enough sunlight to be visible under favorable conditions, but altitude and horizon position alone do not determine brightness. Illumination angle, spacecraft orientation, range, atmospheric clarity and local light pollution can all change what you see. For a broader search across potentially visible objects, use Satellites Above Me Tonight.
Why the displayed orbit can change
Newly launched spacecraft may raise or adjust their orbits. Operational satellites also perform station-keeping and collision-avoidance maneuvers. Public tracking observations are incorporated into newer orbital elements, which is why source freshness matters more than an old screenshot of a previous orbit. CelesTrak publishes public orbital data and background at CelesTrak.
Compare Amazon Leo with other LEO constellations
For a much larger established broadband constellation, open the Starlink Live Tracker. To look for a recently launched Starlink group rather than the whole constellation, use Starlink Train Tonight. The ISS tracker provides a useful contrast because it follows one crewed spacecraft rather than a large network.
