Abstract

determinação de tempo de satélite para receptor sps métodos e aparelho para o aperfeiçoamento de desempenho de localização de posição, especialmente em áreas de cobertura fraca, são descritos aqui. sps é capaz de solucionar a localização de situações nas quais pelo menos dois sinais um receptor posição em de satélite podem ser recebidos, mas apenas um selo de tempo pode ser demodulado com sucesso. o receptor pode utilizar a referência de tempo decodificada com sucesso para determinar um tempo associado com as transições de borda de bit para sinais desse satélite. o receptor utiliza atransição de borda de bit com o tempo conhecido para configurar o tempo para pelo menos uma transição de borda de bit para sinais de outros satélites para os quais o selo de tempo não é demodulado. o receptor configura a hipótese de tempo para as transições de borda de bit ocorrendo dentro de uma janela predeterminada incluindo a transição de borda de bit com o tempo conhecido. uma posição pode ser determinada com base na hipótese de tempo. a hipótese de tempo e a colocação de janela podem ser modificadas seguindo soluções de posição inválidas.
