Abstract
"RECEPTOR DE SISTEMA DE POSICIONAMENTO GLOBAL E PROCESSO DE RECEPçãO DE UM SINAL DE SISTEMA DE POSICIONAMENTO GLOBAL". Um receptor de sistema de posicionamento global inclui um terminal de sinal de entrada para receber um sinal de sistema de posicionamento global de entrada tendo um código PRN de entrada de uma fonte de sinais de sistema de posicionamento global. Um gerador de código PRN local é configurado para gerar um sinal PRN local. Um discriminador é acoplado com o terminal de sinal de entrada e com o gerador de código PRN local e configurado para comparar o sinal de entrada e o código PRN local e gerar um sinal discriminador contendo uma parte positiva e uma parte negativa. Um processador (1205) é acoplado com o discriminador e configurado para receber o sinal discriminador para processar o sinal discriminador para determinar um código de bit e determinar uma distância uma fonte de sinal de sistema de posicionamento global baseado sobre o código de bit. Em uma concretização, o discriminador inclui um modo de aquisição configurado para adquirir o código PRN de entrada no qual o discriminador tem uma primeira largura de porta e um modo de rastreamento configurado para rastrear o código PRN no qual o discriminador tem uma segunda largura de porta menor que a primeira largura de porta. Entre as vantagens da invenção se incluem rejeição de sinal de multivia aperfeiçoada.
