Abstract: PROBLEM TO BE SOLVED: To reduce the time for positioning in a positioning system of GPS base.
SOLUTION: Satellite ephemeris data associated with satellite vehicles is selectively transmitted to a mobile station within a wireless communication system. The mobile station can selectively request satellite ephemeris data from a position determination entity (PDE) that is in communication with one or more GPS satellite vehicles (SV). The mobile station forecasts the satellite vehicles that theoretically are available. Then, the mobile station checks to see if valid ephemeris data is locally stored. If ephemeris data is desired and not locally available, 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. The selective ephemeris request and selective satellite update method can be implemented in accordance with presently available positioning standards.

Abstract translation: 要解决的问题：减少GPS基座定位系统的定位时间。 解决方案：与卫星车辆相关联的卫星星历数据被选择性地发送到无线通信系统内的移动台。 移动台可以从与一个或多个GPS卫星车辆（SV）通信的位置确定实体（PDE）中选择性地请求卫星星历数据。 移动台预测理论上可用的卫星车辆。 然后，移动台检查是否有效的星历数据被本地存储。 如果星历数据是期望的而不是本地可用的，则移动台向PDE发送选择性星历请求，并且响应于该请求接收与在星历表中确定的SV相对应的星历表。 选择性星历请求和选择性卫星更新方法可以根据目前可用的定位标准来实现。 版权所有（C）2011，JPO＆INPIT

Abstract: Satellite ephemeris data associated with satellite vehicles in a Global Positioning System (GPS) based position location system can be selectively transmitted to a mobile station within a wireless communication system. The mobile station can selectively request satellite ephemeris data from a Position Determination Entity (PDE) that is in communication with one or more GPS satellite vehicles (SV). The mobile station forecasts the satellite vehicles that theoretically are available. Then, the mobile station checks to see if valid ephemeris data is locally stored. If ephemeris data is desired and not locally available, 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. The selective ephemeris request and selective satellite update method can be implemented in accordance with presently available position location standards.

Abstract: Los datos de efemerides del satelite asociados con los vehiculos de satelite en un Sistema de Posicionamiento Global (GPS) pueden transmitirse selectivamente, en base al sistema de localizacion de ubicacion, a una estacion movil dentro de un sistema de comunicacion inalambrico; la estacion movil solicita selectivamente los datos de efemerides del satelite desde una Entidad de Determinacion de Ubicacion (PDE) que se encuentra en comunicacion con uno o mas vehiculos de satelite GPS (SV); la estacion movil provee los vehiculos de satelite que estan disponibles teoricamente; entonces, la estacion movil verifica para ver si se almacenan localmente los datos de efemerides validos; si se desean y no estan disponibles localmente los datos de efemerides, la estacion movil transmite una solicitud de efemerides selectiva a la PDE y recibe, en respuesta a la solicitud, las efemerides correspondiente al SV identificado en la solicitud de efemerides; puede implementarse la solicitud de efemerides selectiva y metodo de actualizacion de satelite selectivo de acuerdo con las normas de localizacion de ubicacion actualmente disponibles.
