Abstract

MéTODO E DISPOSITIVO PARA MITIGAR O EFEITO DE UM ERRO INDUZIDO POR MULTI-TRAJETO EM UM SISTEMA DE SATéLITE DE NAVEGAçãO GLOBAL. São descritos um sistema e método para mitigar um erro induzido por multi-trajeto em um sistema de satélite de navegação global (GNSS). Em uma realização do método, é recebido um sinal compósito. O sinal compósito inclui um sinal de trajeto direto limitado em banda e pelo menos um sinal de multi-trajeto limitado em banda que são modulados, cada um, com inversões de fases periódicas. O sinal compósito é medido como uma função do tempo durante um intervalo de tempo possuindo pelo menos uma das inversões de fases periódicas. Um erro de fase <237><sym>, entre o sinal compósito e o sinal de trajeto direto devido ao sinal de multi-trajeto é determinado usando o sinal compósito medido como uma função do tempo, e uma característica de filtro predeterminada correspondente a um filtro usado para limitar em banda o sinal de trajeto direto e o sinal de multi-trajeto. O erro de fase <237><sym>, em uma computação de navegação, é corrigido.
