Method and system for GNSS assistance data or LTO data download over a broadcast band

摘要

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.
