Spacebus 4000

Spacebus 4000 is a highly advanced satellite bus designed and manufactured by Thales Alenia Space, a leading European Space Agency contractor, in collaboration with Arianespace, a prominent launch services company. The Spacebus 4000 platform has been used in numerous communications satellite missions, including Intelsat, Eutelsat, and Inmarsat projects, launched from the Guiana Space Centre using Ariane 5 rockets. The development of the Spacebus 4000 was influenced by the success of earlier satellite bus designs, such as the Spacebus 3000, which was used in Television broadcast satellite and Telecommunications satellite missions for SES S.A., Telenor, and Hispanasat. The Spacebus 4000 has also been compared to other modern satellite bus designs, such as the Boeing 702, used in Intelsat 22 and Intelsat 27 missions, and the LS-1300, used in Intelsat 30e and Intelsat 31 missions.

Introduction

The Spacebus 4000 is a versatile and reliable satellite bus platform, designed to support a wide range of communications satellite missions, including Television broadcast satellite, Telecommunications satellite, and Navigation satellite applications. The platform has been used in several high-profile missions, including the Thor 7 satellite, launched for Telenor in 2015, and the Eutelsat 3B satellite, launched for Eutelsat in 2014. The Spacebus 4000 has also been selected for use in future missions, such as the Eutelsat Quantum satellite, scheduled for launch in 2025, and the Inmarsat-6 satellite, scheduled for launch in 2026. The development of the Spacebus 4000 was supported by the European Space Agency, which provided funding and technical expertise through its ARTES program, in collaboration with Arianespace, Thales Alenia Space, and other industry partners, including SES S.A., Intelsat, and Inmarsat.
