Amazon Leo, formerly known as Project Kuiper, is a mega constellation of satellites in Low Earth Orbit that will offer broadband internet access, this constellation will be managed by Kuiper Systems LLC, a subsidiary of Amazon. This constellation is planned to be composed of 3,276 satellites. The satellites are projected to be placed in 98 orbital planes in three orbital layers, one at 590 km, 610 km and 630 km altitude. 35-40 satellites will be carried on each Ariane 6 launch.
Last Update: Changed name for batches of Amazon Leo/Project Kuiper satellites to be launched on Ariane 6.

Intelsat 45 is a small geostationary communications satellite that will provide Ku-band fixed-satellite services enabling Intelsat to provide specialized and efficient service to Media and Network customers. IS-45 weighs about 1 metric ton at launch and is designed and built by SWISSto12, based on the company’s innovative HummingSat platform. HummingSats are just over one cubic meter in volume, one-tenth the size of conventional satellites placed in geostationary orbit. SWISSto12 is developing the satellites in collaboration with the European Space Agency (ESA) through its public-private-partnership program, benefiting from unique and patented 3D printing technologies.
