Abstract

"PROCESSO E DISPOSITIVO PARA DETERMINAR O TEMPO DE TRâNSITO ENTRE UMA NAVE ESPACIAL E UMA ESTAçãO SOLO". A invenção diz respeito a um processo e a um dispositivo para determinar o tempo de trânsito <sym>T dos sinais entre uma estação solo equipada com um sistema solo (3), e uma nave espacial equipada com um sistema bordo (14). Gera-se no sistema solo (3) e emite-se para a nave espacial uma trama de sincronização TC-Dist que compreende pelo menos um bit de sincronização; mede-se e grava-se na estação solo o intervalo de tempo solo <sym>tsolo entre o instante de emissão do bit de sincronização e o instante de recepção de um bit de referência de uma trama de telemedida do qual se grava o número NTs, gera-se e emite-se para a nave espacial uma trama de medida TC-mes, que incorpora <sym>tsolo e NTs, mede-se a bordo da nave espacial o intervalo de tempo <sym>tbordo entre a recepção do bit de sincronização e a emissão do bit de referência de uma trama de tele-medida cujo número de trama NTb é gravado, calcula-se o tempo de trânsito <sym>T pela fórmula: 2<sym>T = <sym> - <sym>tsolo + (NTb - NTs) x d trama-meio(solo) - meio (bordo) ruído (solo) - ruído (bordo).
