TRACKER GUIDE & MISSION EXPLAINER
OneWeb Satellite Tracker: LEO Broadband Constellation Explained
OneWeb is a low Earth orbit communications constellation operated within Eutelsat's multi-orbit network. The directory above identifies individual OneWeb spacecraft and opens a full SGP4-based tracker for the selected NORAD catalog object.
Eutelsat describes the network as more than 600 satellites arranged in 12 synchronised orbital planes at about 1,200 kilometres altitude. The constellation is designed for high-speed, low-latency connectivity across land, sea and air.
Why OneWeb uses many orbital planes
A low-orbit spacecraft covers a smaller region than a geostationary satellite and moves rapidly relative to the ground. Continuous service therefore depends on a coordinated fleet, ground infrastructure and handovers as different satellites cross a user's sky. Near-polar orbital planes help extend coverage to high latitudes.
Individual satellites share a common network purpose but do not share a single position. The directory is therefore an essential part of the tracker rather than an optional list.
What happens after you select Track
The chosen NORAD ID is used to load current orbital elements. SGP4 estimates the spacecraft's position, which is converted into the marker, ground track, altitude and speed. Observer coordinates then provide local azimuth, elevation, range and geometric passes.
These values describe orbit geometry only. The tracker cannot determine whether a communications beam is active, whether capacity is available or whether a user terminal can connect.
A practical exploration method
- Choose two OneWeb satellites with different names or IDs.
- Compare their ground tracks and notice the shared high-inclination pattern.
- Observe how quickly each moves relative to your location.
- Compare OneWeb altitude with Starlink or GPS satellites.
- Use the pass table as an orbital-learning tool, not a service-coverage prediction.
Educational value and accuracy
OneWeb offers a clear example of the trade-off between altitude, latency, footprint and constellation size. A higher LEO altitude creates a larger view of Earth than a lower LEO orbit, but signals travel farther and debris lifetime can differ.
The page is independent of Eutelsat. Manoeuvres and data age can shift predictions, especially during orbit raising or replacement activity. Official company sources should be used for network and service information.
Constellation replenishment and sustainability
A communications constellation must be maintained as spacecraft age, fail or reach end of life. Replacement launches and responsible disposal are therefore part of the system architecture, not exceptional events. The orbital directory provides a snapshot of catalogued objects, while long-term study can reveal additions and changes. Students should avoid treating the number shown on one day as a permanent fleet total and should distinguish deployed, operational, spare and retiring spacecraft.
Frequently asked questions
How high do OneWeb satellites orbit?
Eutelsat describes the main constellation as operating at about 1,200 kilometres, though individual catalogued objects may temporarily differ.
Why does OneWeb need hundreds of satellites?
Satellites in low Earth orbit move across the sky, so many coordinated spacecraft are used for broad, continuing coverage.
Does a geometric pass mean I can use OneWeb service?
No. A pass is an orbit calculation and says nothing about service authorization, beam coverage or terminal compatibility.
Is this official Eutelsat telemetry?
No. SpaceTracker.live propagates public orbital elements and is independent of the operator.

Educational-use note: SpaceTracker.live is an independent educational website and is not an official mission-control service. Positions, paths, distances and pass predictions are computed from third-party orbital elements or ephemerides. They may be delayed or approximate and must not be used for navigation, collision avoidance or safety-critical decisions.
