Star One D2

Star One D2 satellite, operated by the Brazilian operator Embratel is a high-capacity, multi-mission satellite with Ku-, Ka-, C- and X-band transponders that will enable it to expand broadband coverage to new regions in Central and South America, provide internet access to underserved populations and add an updated X-band payload for government use over the Atlantic region. This powerful, multi-mission communications satellite built on Maxar’s proven 1300-class platform at the company’s Palo Alto, California, manufacturing facility, Star One D2 will improve access to high-quality services, serving the parabolic fleet in Brazil, Pay TV, cell phone backhaul, data, video and Internet for corporate customers and government agencies.

Star One D2 satellite hosts multiple payloads, which will enable it to expand broadband coverage to new regions, provide internet access to underserved populations and add an updated X-band payload for government use over the Atlantic region.

Maxar has decades of mission experience working closely with customers to design, manufacture and operate communications and Earth observation satellites, among other spacecraft. Maxar is a world leader in commercial GEO communication satellites and a global leader in commercial satellite manufacturing.

Star One D2 is the third satellite that Maxar has manufactured for Embratel. Maxar previously built Star One C4, which launched in July 2015 and provides direct-to-home television service in Brazil, and Star One D1, which launched in December 2016 and was the first satellite in Embratel’s fourth-generation family of satellites.


EUTELSAT QUANTUM satellite: revolutionizing telecoms markets with its active antenna is a first for the European commercial telecommunications industry. It will enable users in government, mobility and data markets in order to actively define and shape the performance to reach they need from the satellite. Using a software-based design, EUTELSAT QUANTUM will be the first universal satellite to repeatedly adjust to business requirements.

It features an electronically steerable receiving antenna and operates in Ku-band with eight independent reconfigurable beams. This configuration allows the operator to reconfigure in-orbit the radio-frequency beams over the coverage zones, providing unprecedented flexibility in data, government and mobility services. This new antenna technology complements new generation fully digital payloads where the operator can thus change the coverage, frequencies and the power of its spacecraft.

It is developed under a public-private partnership between ESA, operator Eutelsat and Airbus Defence and Space.

The EUTELSAT QUANTUM satellite is a world first, marking the start of a new era of commercial satellites. Putting agility and flexibility in the hands of Eutelsat’s customers, the satellite paves the way for dynamic resource management to meet changing demands in real-time.
