Abstract
"MÉTODOS PARA DETERMINAR UM VALOR DE AMBIGÜIDADE FLUTUANTE CORRESPONDENTE A UMA MEDIÇÃO DE FASE DE PORTADORA E PARA POSICIONAR OU NAVEGAR UM OBJETO ASSOCIADO A AMBOS RECEPTOR DE REFERÊNCIA LOCAL E UM SISTEMA DE POSICIONAMENTO POR SATÉLITE DE ÁREA EXTENSA, RECEPTOR DE NAVEGAÇÃO POR SATÉLITE, E, MEIO LEGÍVEL POR COMPUTADOR". A presente invenção inclui um método para um uso combinado de um sistema RTK local e um sistema de posicionamento de fase de portadora diferencial, regional de área extensa ou global (WADGPS) no qual as desvantagens associadas às técnicas de navegação RTK e WADGPS quando usadas separadamente, são evitadas. O método inclui usar uma posição conhecida de um receptor de usuário que tenha estado estacionário ou usando um sistema RTK para inicializar os valores de ambigüidade flutuantes no sistema WADGPS, quando o receptor de usuário está se movendo. Posteriormente, as medições de fase de portadora corrigidas por refração obtidos no receptor GPS do usuário são ajustados, incluindo os valores de ambigüidade flutuantes iniciais correspondentes e os valores de ambigüidade flutuantes são tratados como bem conhecidos (pequena variância) nos processos subseqüentes para posicionar o receptor do usuário no sistema WADGPS.
