Eutelsat 3D Satellite Mission and Technology

The Eutelsat 3D satellite is a cutting-edge spacecraft designed to provide high-quality broadcasting services to Europe, North Africa, and the Middle East. It was launched in 2014.

The satellite features a unique three-axis stabilization system, which ensures stable and precise pointing of the satellite's antennas. This technology allows for high-gain beams to be directed at specific regions, increasing signal strength and reducing interference.

Eutelsat 3D has a powerful transponder payload, with a total of 40 transponders in Ku-band and 6 in Ka-band. This enables the satellite to support a wide range of broadcasting services, including TV channels, radio stations, and internet connectivity.

The Eutelsat 3D satellite was built by Thales Alenia Space using their spacebus 4000 satellite bus, which has a launch mass of about 5,470kg.

It has a design lifespan of about 15 years and was launched on May 14, 2013, at 16:02 UTC using a Proton-M rocket with a Briz-M upper stage.

The satellite has four footprints and broadcasts on both the Ka band and the Ku band, with three footprints serving Europe, the Middle East, Central Asia, and North Africa in both Ka and Ku bands.

Here are the satellite's orbital parameters:

The satellite has 56 transponders in total, with 53 Ku- and 3 Ka-band transponders.

Eutelsat Satellites (W3B, W3C, 16A) were designed and manufactured by Thales Alenia Space, a renowned company in the satellite industry. They are used for communication services across Europe, the Middle East, and Africa.

The Eutelsat W3B satellite, launched in 2010, was equipped with 53 Ku-band and 3 Ka-band transponders. It was intended to provide broadcast and telecommunications services, but unfortunately, it developed a sizeable leak in the propulsion system directly after launch and was declared a total loss.

The Eutelsat W3C satellite, launched in 2011, was an identical twin of the W3B and was also designed to provide communication services. It was later renamed Eutelsat 16A and is still operational.

The Eutelsat 3D satellite, launched in 2013, is a communications satellite that provides services to Europe, North Africa, the Middle East, and Central Asia. It has 56 transponders in total, with four footprints that serve different regions.

Here are the key specifications of the Eutelsat W3B, W3C, and 3D satellites:

These satellites are an important part of the Eutelsat fleet, providing critical communication services to various regions around the world.

The Eutelsat 3D satellite was designed and manufactured by Thales Alenia Space, with a launch mass of about 5,470kg.

It features a design lifespan of about 15 years, which is impressive for a satellite of its size. The satellite was transported to Baikonur Cosmodrome in April 2013.

The Spacebus 4000C4 platform, manufactured by Thales Alenia Space, was used for the satellite's design. This platform features upgraded avionics.

Spacebus 4000 is a medium-class satellite bus with a launch mass ranging from 3,000kg to 5,900kg, depending on the version. The C4 version, like the one used for Eutelsat 3D, can accommodate different payloads.

The satellite bus provides solar power capabilities up to 15.8kW, which is essential for a satellite's operation.

The Eutelsat 3D satellite was launched using the Proton Breeze M rocket on May 14, 2013.

The Proton Breeze M rocket was manufactured by Khrunichev, and International Launch Services (ILS) provided the launch services for the satellite.

The rocket had three stages, with six RD-276 engines in the first stage, three RD-0210 engines in the second stage, and one RD-0213 engine in the third stage.

The first stage used about 419.4t of propellants for liftoff, while the second stage used 156.1t of propellants and the third stage used about 46.5t of propellants.

The Proton booster had a diameter of 7.4m in the first stage and 4.1m in the second and third stages, with a total height of 42.3m.

The separation of the satellite took place nine hours and 13 minutes after liftoff, with five engine firings in the upper stage.
