"We will be working together to incorporate innovative solutions, based on our proven expertise and long experience in the design, development and production of satellite system for LEO constellations.

“This latest phase will finalise the manufacturing plan, paving the way for the production and deployment of the entire constellation."

Featuring optical inter-satellite links, gigabit class, onboard processors, flexible steerable antennas, and RF (radio-frequency) over PCB (printed circuit boards), the LeoSat satellites will use an improved EliteBus™ platform.

These features will enable the constellation to provide higher payload power and mass while reducing launch cost.

Thales Alenia Space recently won a contract to provide the SES-17 powerful high-throughput satellite to operator SES.
