Abstract

MÉTODO PARA GERAR UMA MEDIÇÃO DE FASE DE PORTADORA, E, SISTEMA DE POSICIONAMENTO OU NAVEGAÇÃO Uma nova técnica de três freqüências para obter medições de fase de portadora livres de geometria, corrigidas em refração, resolvidas em ambigüidade, foi descrita. Primeiro, as ambigüidade em pelo menos duas diferenças de medição de fase de portadora de faixa larga são obtidas 210 calculando em média as medições de código ponderadas em freqüência correspondentes. Estas duas medições resolvidas em ambigüidade são estão combinadas em uma medição corrigida em refração compósita 220. A medição compósita resultante é bastante ruidosa devida à amplificação do ruído de multitrajeto nas medições de fase de portadora originais. Mas esta medição de fase de portadora corrigida em refração ruidosa pode ser suavizada com outra medição compósita de fase de portadora de mínimo ruído, corrigida em refração. A medição compósita corrigida em refração de mínimo ruído 230 é construída das medições de fase de portadora primárias antes de resolver suas ambigüidades de ciclo inteiro. Suavizando 240 a diferença nas duas medições corrigidas em refração, o ruído pode ser reduzido e a polarização na medição de baixo ruído (devido a ambigüidades incorretas) pode ser estimada e subseqüentemente corrigida.
