About this launch
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.
