Eutelsat Satellite Fleet and Orbital Infrastructure
Eutelsat operates a sophisticated network of satellites designed to provide global communication capacity. The company manages capacity on 36 satellites positioned in geosynchronous orbit—an orbit where the satellite matches the Earth's rotation, appearing stationary over a fixed point on the ground. These assets are strategically distributed between 139° West and 174° East to ensure comprehensive global coverage.
To maintain a clear and organized fleet, Eutelsat implemented a standardized naming convention on March 1, 2012. Most satellites now carry the Eutelsat name, followed by their orbital position and a letter indicating their sequence of arrival at that specific location. This branding alignment was further extended to Eutelsat Americas (formerly Satmex) on May 21, 2014.

Key Facts
- Fleet Scale: Sells capacity on 36 satellites in geosynchronous orbit.
- Global Reach: Orbital positions span from 139° West to 174° East.
- Technological Milestone: The Eutelsat Konnect VHTS features the most powerful on-board digital processor ever put in orbit.
- Innovation: Eutelsat Quantum is the first in-orbit reprogrammable satellite.
- Modern Platforms: Eutelsat Konnect was the first to utilize the all-electric Spacebus NEO platform by Thales Alenia Space.
Current Fleet and Technical Specifications
The Eutelsat fleet consists of various satellite generations, ranging from traditional communication satellites to Very High Throughput Satellites (VHTS), which provide significantly higher data speeds and capacity.
High-Capacity and Modern Assets
Recent additions to the fleet emphasize efficiency and flexibility. The Eutelsat Konnect VHTS, launched in September 2022 via an Ariane 5 ECA, serves Europe with advanced digital processing. Similarly, the Eutelsat Quantum (launched July 2021) introduces the ability to be reprogrammed while in orbit, serving the Middle East and North Africa.
The fleet also utilizes the all-electric Eurostar Neo bus, as seen in the Hotbird 13F and 13G satellites launched in late 2022 via Falcon 9 Block 5.
Regional Coverage and Orbital Positions
Eutelsat distributes its assets to cover specific geographic regions. For example, the Hot Bird series (such as 13B, 13C, and 13E) primarily serves Europe, North Africa, and the Middle East. In the Americas, satellites like Eutelsat 65 West A and the former Satmex series (now Eutelsat 113, 115, and 117 West) provide essential connectivity.

Fleet Evolution: Rented, Former, and Future Assets
Rented Capacity
Beyond its owned fleet, Eutelsat utilizes rented capacity to expand its reach. This includes the Astra 2E, 2F, and 2G satellites at 28.2°E serving Europe, as well as the Ekspress-AT and SESAT 2 satellites.
Legacy and Retired Satellites
The company's history includes numerous retired assets, such as the Eutelsat I series (F-1, F-2, F-4, F-5) and early Hot Bird models. Some satellites, like Eutelsat 33B, experienced technical anomalies (such as the loss of a solar panel in 2008) before being redeployed or retired. A small number of missions resulted in launch failures, including Eutelsat I F-3, Eutelsat 2 F-5, and Hot Bird 7.
Future Developments
Eutelsat continues to evolve its infrastructure, with the Flexsat satellite scheduled for launch in 2026.
Frequently Asked Questions
What is the naming convention for Eutelsat satellites?
Since March 2012, satellites are generally named "Eutelsat" followed by their orbital position (e.g., 10A) and a letter indicating the order in which they arrived at that position.
What makes Eutelsat Quantum unique?
Eutelsat Quantum is the first satellite in orbit that is fully reprogrammable, allowing for greater flexibility in how it serves its target regions.
Which satellites use the all-electric Spacebus NEO platform?
Eutelsat Konnect was the first satellite to use the Thales Alenia Space all-electric Spacebus NEO platform.
What is a VHTS satellite?
VHTS stands for Very High Throughput Satellite. These satellites, such as the Eutelsat Konnect VHTS, provide significantly higher data capacity and processing power than traditional satellites.
Which launch vehicles does Eutelsat commonly use?
Eutelsat utilizes a variety of launch vehicles, including the Ariane 5 ECA, Falcon 9, Proton-M / Briz-M, and Zenit-3SL.
