Abstract

1 / 1 resumo “receptor do sistema de satã‰lite navegacional global (gnss), e, mã‰todo para detecã‡ãƒo da manipulaã‡ãƒo de sinais de satã‰liteâ€� ㉠aqui divulgado um sistema para detecã§ã£o da manipulaã§ã£o de um sinal gnss e mitigaã§ã£o contra tal manipulaã§ã£o. um receptor do gnss recebe sinais gnss a partir de uma pluralidade de satã©lites gnss e calcula tempos de evento para cada satã©lite gnss. o receptor do gnss, entã£o, compara um prã³ximo tempo do evento para um satã©lite gnss em particular com um prã³ximo tempo do evento esperado para o satã©lite gnss em particular. se a diferenã§a entre o prã³ximo tempo do evento esperado e os prã³ximos tempos de evento exceder um limite predeterminado, entã£o, o receptor do gnss indica que integridade do sinal pode estar comprometida.
