Title: (DA) Satellitbaseret bekræftelses-bagud søgesystem
Abstract:
(EN) A satellite based paging communication system comprises at least one satellite (102) capable of communicating the paging information to at least one terrestrial receiver (110, 116, 126) some of which are capable of transmitting an acknowledge signal (127) so that message reception may be verified and satellite traffic controlled.
