EUTELSAT 10B

About This Satellite

EUTELSAT 10B launched on November 23, 2022 for communications services at 10 degrees east. Built by Thales Alenia Space on the all-electric Spacebus NEO platform, it combines high-throughput connectivity with conventional widebeam services. Its mission includes connections to aircraft and ships, where the useful coverage follows routes across oceans as well as populated land.

Two high-throughput payloads serve different regions

Eutelsat describes two Ku-band multibeam payloads. One addresses the North Atlantic corridor, Europe, the Mediterranean, and the Middle East; the other reaches the Atlantic, Africa, and the Indian Ocean. Separate C- and Ku-band widebeam payloads were included for continuity of services associated with EUTELSAT 10A. These are different service footprints, not one uniform global signal.

Gigahertz and gigabits per second describe different quantities

The operator lists more than 50 GHz of processed bandwidth and approximately 35 Gbps of throughput for the high-throughput payloads. Frequency bandwidth and data rate are not interchangeable units. Neither figure is a promised speed for an individual passenger, vessel, or terminal; the advertised total does not specify a customer's allocated capacity.

Launch and commercial service were separate milestones

Eutelsat announced successful entry into service on July 24, 2023, following the November 2022 launch. A spacecraft reaching orbit is therefore not the same event as a customer service becoming available. When reading historical coverage announcements, distinguish the launch date, orbital location, and service announcement rather than using the first tracked position as the start of commercial operations.

Digital processing makes capacity allocation more flexible

Thales Alenia Space describes a fifth-generation digital transparent processor that allows capacity to be allocated dynamically between beams as demand changes. This flexibility concerns the communications payload, not moving the entire satellite to follow an aircraft. The manufacturer also states a nominal lifetime of at least fifteen years; that is a design specification, not evidence that every service will remain unchanged for that period.

Reading this orbital snapshot

Based on TLE epoch: 2026-09-05. Estimated altitude ranges from 35,783 km at perigee to 35,791 km at apogee, a difference of 8 km. The orbital period is about 1436.1 minutes. Eccentricity 0.00010 indicates a nearly circular path. In a two-body approximation, perigee speed is 1.00 times apogee speed. These are mean-element estimates, not instantaneous measurements. Distance per orbit uses an ellipse approximation.

Saved build snapshot. If a valid TLE is retrieved, this explanation and the orbit panel update together. Otherwise this dated snapshot is retained.

Ground track is not sensor coverage

An inclination of 0.06 degrees implies approximate geocentric ground-track limits of 0.1 degrees north and south. This is a prograde orbit, moving in the same general direction as Earth rotation. The plotted line marks the point beneath the object. It does not represent camera coverage, radio reception, or a guaranteed visible pass.

Is it fixed above one longitude?

The snapshot period is 1436.1 minutes. A sidereal day is about 1,436.07 minutes. Height alone does not establish a geostationary orbit: the period must match Earth rotation and the path must be circular and equatorial. This catalog uses a five-minute period tolerance for near-geosynchronous labels; near-geostationary additionally requires inclination at most 1 degree and eccentricity at most 0.01. These are browsing categories, not evidence of station-keeping or a fixed longitude.

Accuracy and missing information

The introductory record describes the build snapshot. The orbital snapshot explanation and orbit panel share any successfully retrieved TLE; check the displayed epoch. Reentered objects retain historical data only. Mission history is not rewritten by TLE updates. TLE/SGP4 positions are predictions and can change after maneuvers or updated observations. The 14-day stale-data cutoff is a display safeguard, not an accuracy guarantee. Local passes are geometric predictions, not a visibility forecast. No verified operator or mission status means unknown, not active. Do not use this catalog for collision avoidance or operational flight decisions.
