A 5 m-diameter antenna reflector, designed for orbital operations, seen during a test deployment during ESAs latest Large Deployable Antenna Workshop.
Large-scale antenna reflectors are increasingly required for telecommunications, science and Earth observation missions.
This metal mesh reflector has a double pantograph design to form a deployable ring. Once deployed it tensions two opposing, but connected, parabolic shaped nets, one on the top and one on the bottom.
