SpaceLink is a company building a data relay network for the space economy. As a subsidiary of Electro Optic Systems (EOS), SpaceLink is constructing a satellite relay system in Medium Earth Orbit (MEO) that uses optical intersatellite links to provide secure, continuous, high-capacity communications between spacecraft in Low Earth Orbit (LEO) and the ground. Their services support various applications like Earth observation, human spaceflight, and secure data transfer for government and commercial entities and has been awarded contracts by NASA and DARPA. SpaceLink aims to provide a TDRSS-like capability with greater capacity, leveraging advancements in optical communications.
