We present a satellite-compatible reconfigurable quantum network architecture. During the satellite-pass the network adopts a point-to-multipoint topology where all the users communicate with the satellite, whereas outside of a satellite pass, the signal is rerouted to form a fully-connected network between the ground users. Exploiting multiplexing techniques, we show simulation results that indicate that this scheme can be used to enhance the secure key rate and to connect a multitude of users on the ground with minimal hardware requirements.
