1. A geostationary orbit (GSO) satellite for relayed communications comprising:

  • an antenna for receiving a spot beam signal from a GSO earth station;

    a down converter coupled to the antenna for generating a down-converted signal from the received spot beam signal;

    a band-pass filter coupled to the down converter and having a frequency response that allows passing of a signal at least partially occupying a frequency spectrum allocated to a non-geostationary orbit (NGSO) signal on a primary basis, for generating a first output signal based on the down-converted signal; and

    a switch coupled to the band-pass filter and having a first and a second position, wherein in the first position, the switch permits transmission of the first output signal toward Earth, and wherein in the second position, the switch suppresses transmission of the first output signal toward Earth; and

    wherein the switch is controllable to be placed in the first or the second position based on information relating to occurrence of an in-line event involving the GSO satellite and an NGSO satellite.
