Abstract

"MéTODO, EQUIPAMENTO E SISTEMA PARA PREVISãO DE SINAL". Um equipamento, um método e um sistema para prever subframes de sinais GPS. O equipamento inclui um processador capaz de determinar se um subframe é um subframe de almanaque, ajustar um timehead e adiciona-lo a uma TOW, ajustar uma mensagem TLM com base em um valor da TOW, gerar uma CRC para um subframe previsto e uma memória para armazenar o subframe previsto. A memória pode variar em tamanho com base no número de subframes previstos. O processador é também capaz de determinar se o valor da TOW é menor que o número de segundos em uma semana, calcular uma posição do subframe previsto na memória e ajustar um flag válido.
