Abstract
A satellite signal routing system includes a satellite using one or more waveguide switches for routing M-inputs to M of N-outputs. A waveguide switch includes a first waveguide, used as a stationary input coupled to a rotary joint. A joint rotation device, such as a motor, rotates the rotary joint. A rotary waveguide is attached to the rotary joint and also rotates. Two or more second waveguides, used as stationary outputs, are coupled to the rotary waveguide through a non-contacting waveguide. A controller controls the joint rotation device to rotate the rotary joint to align the rotary waveguide with one of the second waveguides.
