Abstract

MÉTODOS PARA CRIAR UM CONJUNTO DE CÓDIGOS DE ESPALHAMENTO PARA USO EM UM SISTEMA DE NAVEGAÇÃO POR SATÉLITE, RECEPTOR, DISPOSITIVO DE MEMÓRIA REMOVÍVEL, SATÉLITE, SINAL DE SATÉLITE, APARELHO PARA USO COMO PARTE DE UM SISTEMA DE NAVEGAÇÃO POR SATÉLITE, E, MÉTODOS PARA OPERAR UM RECEPTOR E UM SATÉLITE Uma modalidade da presente invenção fornece um método de criar um conjunto de códigos de espalhamento para uso em um sistema de navegação por satélite compreendendo uma constelação de satélites. A cada satélite na constelação é para ser alocado um código de espalhamento do conjunto de códigos de espalhamento . Método compreende gerar um conjunto inicial de padrões de bit (105), onde cada padrão de bit representa um código de espalhamento potencial, e efetuar um processo de otimização no conjunto inicial de padrões de bit (110). O processo de otimização modifica pelo menos alguns dos padrões de bit no conjunto inicial para criar um conjunto final de padrões para uso como o conjunto de códigos de espalhamento (115) para o sistema de navegação por satélite. Receptores que suportam o sistema de navegação por satélite incorporam o conjunto final de padrões de bit para uso em captura de sinal e determinação de posição.
