Abstract

MÉTODO IMPLEMENTADO POR COMPUTADOR, SISTEMA DE COMPUTADOR, E, MÍDIA DE ARMAZENAMENTO LEGÍVEL POR COMPUTADOR NÃO TEMPORÁRIA. São descritos um sistema e um método para prover melhor informação de correção a receptores de navegação (120) que incluem receber, a partir de uma pluralidade de estações de referência (140-1, 340-2, I40-M) em locais conhecidos, uma pluralidade de medições de navegação por satélite dos sinais provenientes de uma pluralidade de satélites de navegação global 10 (110-1, 110-2, 110-M). Um estado da pluralidade de satélites de navegação global (110-1, 110-2, 110-N) é computado com base nas medições de navegação por satélite recebidas. Referenciais, cada qual correspondente a um par das estações de referência (140-1, 140-2, 140-M), são identificados. Para cada referencial identificado, computam-se valores flutuantes e integrais para uma ambiguidade integral duplamente diferenciada. Ambiguidades integrais duplamente diferenciadas que satisfazem um conjunto de condições predefinidas são identificadas e o estado computado da pluralidade de satélites de navegação global (1104, 110-2, 110-N) é ajustado de acordo com uma restrição de valor integral aplicada em cada ambiguidade integral duplamente diferenciada que satisfaz o conjunto de condições predefinidas. A informação de correção é computada a partir do estado computado ajustado da pluralidade de satélites de navegação global (110-1, 110-2, T 10-N).
