Abstract

um receptor de navegação por satélite multibanda (11) para o rastreamento de portadora e código usando um filtro sigma rho de ponto fixo (42) com estabilidade melhorada é descrito. o receptor (11) simplifica e acelera o processamento de dados no filtro (42) para acomodar adaptivamente informação comum de bandas agregadas e obter a posição precisa do receptor (11) em tempo real. o filtro (42) pode utilizar uma função de desvio padrão e uma função de correlação cruzada enquanto determina fatores de escala adaptivos para assegurar que o filtro (42) seja estável e confiável.
