Abstract

"MéTODO E EQUIPAMENTO PARA COMUNICAçãO DE EFEMéRIDE GPS". Dados de efeméride de satélite associados com os veículos de satélite em um GPS com base no sistema de localização de posição podem ser transmitidos seletivamente para uma estação móvel dentro de um sistema de comunicação sem fio. A estação móvel pode solicitar seletivamente os dados de efeméride de satélite de uma Entidade de Determinação de Posição (PDE) que está em comunicação com um ou mais veículos de satélite (SV) GPS. A estação móvel prevê os SV que teoricamente estão disponíveis. Então, a estação móvel verifica para ver se os dados de efeméride válidos estão armazenados localmente. Se os dados de efeméride desejados não estiverem armazenados localmente, a estação móvel transmite uma solicitação de efeméride seletiva para a PDE e recebe, em resposta à solicitação, a efeméride correspondente ao SV identificado na solicitação de efeméride. A solicitação de efeméride seletiva e o método de atualização de satélite seletivo podem ser implementados de acordo com os padrões de localização de posição atualmente disponíveis."METHOD AND EQUIPMENT FOR GPS EPHEMERID COMMUNICATION". Satellite ephemeris data associated with satellite vehicles in a GPS based position location system can be selectively transmitted to a mobile station within a wireless communication system. The mobile station may selectively request satellite ephemeris data from a Position Determination Entity (PDE) that is in communication with one or more GPS satellite (SV) vehicles. The mobile station predicts the SVs that are theoretically available. Then the mobile station checks to see if valid ephemeris data is stored locally. If the desired ephemeris data is not stored locally, the mobile station transmits a selective ephemeris request to the PDE and receives, in response to the request, the ephemeris corresponding to the SV identified in the ephemeris request. Selective ephemeris request and selective satellite update method can be implemented according to the currently available position location standards.
