Abstract

Patente de Invenção: "MéTODO E EQUIPAMENTO PARA PROCESSAMENTO DE SINAL EM UM SISTEMA DE POSICIONAMENTO POR SATéLITE". Um método e um equipamento para o processamento de sinais de um sistema de posicionamento por satélite (SPS) que possuem nível baixo. Em uma modalidade um receptor SPS recebe pelo menos duas amostras de sinal representando, pelo menos em parte, informações em comum, em que as duas amostras de sinal estão associadas com uma ou mais mensagens de satélite. Pela combinação das duas amostras de sinal, informações de navegação (por exemplo, hora, posição, velocidade, etc.) podem ser determinadas com base na combinação das duas amostras de sinal. De acordo com outra modalidade, as duas amostras de sinal são diferencialmente demoduladas e somadas juntas para formar a combinação.
