Abstract

um sistema de geração de correções de satélite recebe informação de medição do receptor de referência a partir de uma pluralidade de receptores de referência em locais estabelecidos (402). de acordo com a informação de medição do receptor de referência recebida, e locais estabelecidos dos receptores de referência, o sistema determina as soluções de navegação de rota larga para a pluralidade de receptores de referência (404). o sistema também determina os agrupamentos de ambiguidades flutuantes de rota larga com diferença única (sd) (408). um valor de tendência rota larga do satélite para cada satélite de uma pluralidade de satélites é inicialmente determinado de acordo com porções fracionárias das ambiguidades flutuantes de rota larga sd nos agrupamentos e critérios de ajuste de alcance excessivo (412 e 414). um conjunto de correções de satélite de navegação para cada satélite, incluindo o valor de tendência rota larga do satélite para cada satélite, é gerado e transmitido para receptores de navegação para uso na determinação de locais dos receptores de navegação (416 e 418).
