    • A combined GNSS and FM receiver receives FM signals comprising satellite navigation data from an AGNSS server. Associated navigation information such as a position fix is determined based on the received satellite navigation data. The received satellite navigation data are GNSS assistance data or LTO data. The AGNSS server generates the satellite navigation data by acquiring GNSS data from a satellite reference network. The acquired GNSS data comprise, for example, GPS data, GLONASS data and/or GALILEO data. The generated satellite navigation data are broadcasted as FM signals through RDS and/or RBDS to the combined GNSS and FM receiver. The combined GNSS and FM receiver receives updated satellite navigation data in subsequent FM signals, periodically or aperiodically, and updates associated navigation information, accordingly. The combined GNSS and FM receiver decodes the received FM radio signals for the updated satellite navigation data generated at the AGNSS server before being transmitted.
    • 组合的GNSS和FM接收器接收包括来自AGNSS服务器的卫星导航数据的FM信号。 基于接收到的卫星导航数据来确定诸如位置锁定的相关导航信息。 接收到的卫星导航数据是GNSS辅助数据或LTO数据。 AGNSS服务器通过从卫星参考网络获取GNSS数据来生成卫星导航数据。 所获取的GNSS数据包括例如GPS数据,GLONASS数据和/或GALILEO数据。 生成的卫星导航数据通过RDS和/或RBDS作为FM信号广播到组合的GNSS和FM接收机。 组合的GNSS和FM接收机在周期性或不定期地接收后续FM信号中的更新的卫星导航数据,并相应地更新相关的导航信息。 组合的GNSS和FM接收机解码所接收的FM无线电信号,以便在发送之前在AGNSS服务器处生成的更新的卫星导航数据。
