Abstract

medições de fase portadora e medições de código que são acessadas (505) para sinais de satélite de um sistema de satélite de navegação global. um conjunto inicial de ambiguidades de ponto flutuante é determinado (510) com base nas medições, sendo que o conjunto inicial de ambiguidades de ponto flutuante inclui a tendência interfrequência (ifb). os métodos exemplificativos descritos incluem adicionalmente a realização de um processo de pesquisa de mínimos quadrados com base no conjunto inicial de ambiguidades de ponto flutuante para determinar um conjunto de ambiguidades de número inteiro e uma estimativa da ifb (515). em alguns exemplos, um filtro adicional (por exemplo, de rota larga) é usado para realizar uma combinação de fase portadora e ifb de código. em alguns exemplos, a estimativa de ifb resultante e o conjunto de ambiguidades de número inteiro são usados para estimar uma posição de um receptor (520), determinar um sinal de correção de satélite ou outros.
