Abstract

"PROCESSO PARA DETERMINAR A POSIçãO DE UM TERMINAL DE USUáRIO UTILIZANDO SATéLITES DE UM SISTEMA DE POSICIONAMENTO GLOBAL". Um processo é proporcionado para determinar a posição de um terminal de usuário utilizando satélites de sistemas de posicionamento global (GPS), cada um dos satélites de GPS transmitindo um sinal contendo informação indicativa dos parâmetros orbitais dos respectivos parâmetros de satélites de GPS, de dados de tempos e de sincronização e correção de relógio. O processo inclui as etapas de aproximação de uma faixa esperada de freq³ências de Doppler dentro da qual pelo menos um satélite de GPS estará localizado, dentro dessa faixa, busca e aquisição de um primeiro sinal de GPS de um primeiro satélite de GPS no terminal de usuário forte o bastante para demodular, o primeiro sinal GPS contendo informação indicativa dos parâmetros orbitais do primeiro satélite de GPS, dados de tempos e sincronização e parâmetros de correção de relógio, demodulando o primeiro sinal de GPS para obter informação de hora da semana, medição de sincronização de fase de código para o primeiro sinal de GPS, utilizando a informação de hora da semana, busca e aquisição de segundo, terceiro e quarto sinais de GPS no terminal de usuário dos segundo, terceiro e quarto satélites de GPS, respectivamente, medição das sincronizações de fases de códigos para os segundo, terceiro e quarto sinais de GPS, utilizando a informação de hora de serviço e cálculo da posição do terminal de usuário, utilizando as sincronizações de fases de códigos do primeiro ao quarto sinais de GPS.
