An international experiment is being conducted to assess the use of geostationary spacecraft to relay 406 MHz distress beacon signals. The development is described of a signal processor that will search a nominal 10 kHz portion of the 406 MHz band, detect anddemodulate a small number of beacons, and produce an alertmessage with low probability of message error. It is shown that thenominal composite link C/No is about 30 dB Hz. The proposedprocessor is described and simulation results are presented. Theresults indicate that the processor has a threshold of about26 dB · Hz, a message error rate of 2 percent or less, and a messagetransfer time of less than 10 min.
