Abstract

<B>SISTEMA DE LOCALIZAçãO ASSISTIDO POR SATéLITE UTILIZANDO ESTRATéGIA DE BUSCA DE SINAIS SEQ ENCIAS COM BASE EM INFORMAçõES<D> é descrito um método e aparelho para facilitar a detecção de sinais de satélite utilizando uma técnica de busca seq³encial. A técnica de busca seq³encial é uma técnica com base em informações que busca seq³encialmente sinais de satélites com base em mensagens de busca e informações acumuladas durante buscas anteriores para reduzir de modo eficaz a área e a faixa de busca de fase de código nas quais um receptor GPS busca os sinais de satélite melhorando desse modo a detecção dos sinais de satélites.
