H2SAT (HEINRICH HERTZ)

Communications Technology Demonstration · DLR / Germany / OHB

Germany's experimental communications satellite named after the physicist who first proved the existence of electromagnetic waves. Heinrich Hertz carries experimental payloads testing Q/V band communications (frequencies above 40 GHz) and optical laser links — technologies needed for future next-generation satellite communications. Germany's DLR and several commercial partners use it to validate technologies that will appear in operational satellites a decade from now, filling the gap between laboratory and full-scale mission that technology demonstration satellites uniquely address.
