Abstract

1 / 1 resumo “mã‰todo e sistema para detecã‡ãƒo da falha de uma fonte de tempo com precisãƒo usando uma fonte de tempo independente” sã£o divulgados sistemas e mã©todos para detecã§ã£o da falha de uma fonte de tempo com precisã£o usando uma fonte de tempo independente. adicionalmente, a detecã§ã£o da falha de uma fonte de tempo com precisã£o com base no gnss com base em um local calculado de um receptor do gnss ã© divulgada. alã©m do mais, o sistema pode ser adicionalmente configurado para distribuir um tempo derivado a partir da fonte de tempo com precisã£o como uma referãªncia do tempo com precisã£o para dispositivos dependentes do tempo. no evento de uma falha da fonte de tempo com precisã£o, o sistema pode ser configurado para distribuir um tempo derivado a partir de uma segunda fonte de tempo com precisã£o como o sinal de tempo com precisã£o durante um perã­odo remanescente.
