Abstract

1 / 1 resumo “mã‰todo, sistema, e, dispositivo de distribuiã‡ãƒo de tempo” sã£o descritos sistemas e mã©todos para detectar a falha de uma fonte de tempo de precisã£o utilizando uma fonte de tempo independente. adicionalmente, ã© descrita a detecã§ã£o de falha de uma fonte de tempo de precisã£o baseada em gnss, com base em um local calculada de um receptor gnss. ainda mais, o sistema pode ser adicionalmente configurado para distribuir um tempo derivado da fonte de tempo de precisã£o como uma referãªncia de tempo de precisã£o para dispositivos dependentes do tempo. no caso de uma falha da fonte de tempo de precisã£o, o sistema pode ser configurado para distribuir um tempo derivado de uma segunda fonte de tempo de precisã£o como o sinal de tempo de precisã£o durante um perã­odo de espera.
