Description:
The Eurostar E3000 is a generic satellite model most commonly used for commerical and military tele-communications satellites manufactured by Astrium; it is a member of Astrium's Eurostar family. It utilises a chemical, bi-propellant propulsion system for orbit raising and on-station manoeuvres with an optional plasma propulsion system (PPS). The PPS harnesses the newtonion effect as a result of the ionisation of Xenon gas employed by the use of haul-effect plasma thrusters. This system is most commonly used for for North-South station-keeping. The E3000 was the first commercial satellite family to use lithium-ion batteries rather than the older nickel-based technologies for power supply during eclipses.

As always, the basic E3000 bus can be modified extensively to meet customer requirements, but most of the E3000 satellites have a launch mass of between 4500 and 6000 kilograms, and solar arrays between 35 and 45 metres providing between nine and sixteen kilowatts at end of life. They tend to feature between fifty to ninety transponders, most often in Ku-band and C-band.

Satellites built around the E3000 platform include Hispasat's Amazonas 1 and 2, Arabsat 5A, 5B, and 5C, Astra 1M and 3B, Eutelsat's W3A and Hot Bird 8-10, Intelsat 10-02, KaSat, Atlantic Bird 7, W5A Telesat's Anik F1R, Anik F3 and Nimiq 4, Skynet 5A-C and the Inmarsat 4 series of satellites; Each of the three Inmarsat 4 in service has a large deployable reflector as main antenna.
