Eurostar E3000
The Eurostar E3000 is a generic satellite model most commonly used for commercial and military communications satellites manufactured by Airbus Defence and Space (formerly Astrium). It is a member of Airbus Defence and Space'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 Newtonian effect as a result of the ionisation of xenon gas employed by the use of Hall effect plasma thrusters. This system is most commonly used 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. The E3000 bus can be modified extensively to meet customer requirements, but most of the E3000 satellites have a launch mass of between , and solar arrays between providing between nine and sixteen kilowatts at end of life. They tend to feature between 50 and 90 transponders, most often in the Ku-band and C-band. There have been 52 satellites built around the E3000 platform including ANASIS 2, Hispasat's Amazonas 1 and 2, Arabsat-5A, -5B, and -5C, Astra  1M, 1N, 2E, 2F, 2G, 3B and 5B, Eutelsat's W3A and Hot Bird 8–10, Intelsat 10-02, KA-SAT, Atlantic Bird 7, 70B Telesat's Anik F1R, 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 the main antenna. In March 2015, Airbus Defence and Space received a delivery of new 3D-printed brackets for mounting telemetry and tele-command antennas, being the first space-qualified 3D-printed component of its kind. Eurostar E3000EOR. Also in March 2015, Airbus  signed a contract with Snecma for 5-kilowatt PPS5000 Hall-effect thrusters for the E3000 Electric Orbit Raising (E3000EOR) variant of the satellite bus. New thrusters would allow reducing the weight of a satellite by up to 40%., as Türksat 5A and Türksat 5B Eurostar Neo. An improved model based on the E3000 called the Eurostar Neo was announced in 2017, offering electric, hybrid, or chemical propulsion, in addition to a scalable power range of 7 kW to 25 kW.
