Abstract

"MéTODOS PARA OBTER UMA MEDIçãO DE FASE DE PORTADORA GPS DE AMBIGüIDADE RESOLVIDA, REFRAçãO CORRIGIDA, E PARA GERAR UMA MEDIçãO DE FASE DE PORTADORA DE AMBIGüIDADE RESOLVIDA, REFRAçãO CORRIGIDA E RUìDO MINIMIZADO, E, SISTEMA DE POSICIONAMENTO OU NAVEGAçãO". A presente invenção inclui um método para gerar uma medição de fase de portadora de ambigüidade resolvida, refração corrigida e ruido minimizado. O método inclui formar uma primeira medição compósita usando medições de fase de portadora GPS nas freqüências L1, L2 e L5. Para reduzir o ruído na primeira medição compósita, o método inclui adicionalmente formar uma segunda medição compósita usando medições de fase de portadora GPS em pelo menos duas das freqüências de portadora GPS. A segunda medição compósita é formada para ter um pequeno ruído multitrajeto, de tal modo que pode ser usada para suavizar a primeira medição compósita, de tal modo que o ruído de multitrajeto é minimizado.
