satellite picks up the signal and when it relays it just depending on where the satellite is and if it's in range of a LUT when it picks up the signal (up to 90 minute delay). The 406 MHz signal can be detected all over the globe, so the satellites generally pick up and relay this signal and the 121.5 MHz signal is used by SAR units to home in on the EPIRB during the search. Even if you are in a region where the 121. MHz cannot be picked up by the satellites, SAR units are still able to use it for it the same purpose during the rescue efforts.
