Eurostar is the brand name for a satellite bus
Satellite bus
A satellite bus or spacecraft bus is the general model on which multiple-production satellite spacecraft are often based. The bus is the infrastructure of a spacecraft, usually providing locations for the payload .They are most commonly used for geosynchronous satellites, particularly...

 made by Astrium which has been used for a series of spacecraft providing telecommunications services in geosynchronous orbit (GEO). More than 60 Eurostar satellites have been ordered to date, of which 45 have been successfully launched since October 1990 and have proven highly reliable in operational service. Early 2010, the Eurostar satellites accumulated 350 years of successful operations in orbit.
The Eurostar spacecraft series is designed for a variety of telecommunications needs including fixed services and broadcast, mobile services, broadband and secured communications.

Development

Eurostar was designed in the mid 1980’s jointly by Matra Marconi Space and BAe (now integrated within Astrium) to an internally developed specification, for a market which at the time had a design envelope of 1.8-2.5 Tons on the proposed launch vehicles (STS PAM D2 and Ariane 4). Satellite payload power was from 1300 to 2600 W. This was the first commercial satellite to have a digital avionics system modular in concept. With this system architecture, all key satellite parameters are in software, which permits mission specific requirements to be implemented without hardware changes. The initial satellite structure and configuration designed to early requirements had significant growth potential, which subsequently allowed the payload capability (mass and power) to be more quadrupled between 1987 and 1992, with a minimum of re qualification. Astrium has since developed further the product line in a staged process which mainly increases the satellite power and propulsion capability and real estate for accommodation of equipment and antennas. The overall configuration of Eurostar satellites has essentially not changed in 20 years through the successive generations Eurostar E1000, E2000, E2000+ and E3000. They have just become larger, more powerful, with implementation costs reduced through longer orbit manoeuvring lifetime, and more efficient and powerful payloads. Nowadays the Eurostar E3000 series has been considerably enhanced and updated with the latest technologies, still maintaining the basic proven configuration.

Range

The Eurostar E3000 satellite model currently available offers power payload ranging from 4 to 14 kW. Satellites launch mass usually ranges between 4,000 and 6,000 kg.

Modularity

The Eurostar satellite structures are modular with a separate Service-Propulsion module and Communications module. Figure shows the modular design of the E3000 series around a compact Service module.
