ABSTRACT:
The following discloses an improved system and method for accessing location assistance data, such as A-GPS assistance data, with a portable electronic device. In exemplary embodiments, location assistance data is generated by one or more reference radio transmitters and continuously broadcasted therefrom. In a preferred embodiment, the location assistance data may be continuously broadcasted in the form of an RDS feed associated with a broadcasted FM radio station. The location assistance data may include such items of information as satellite ephemeris data, approximate location, and current time. The location assistance data may be received by a radio receiver within the portable electronic device. A controller within the portable electronic device may combine the assistance data with location data received from satellites to enhance the generation of location information.
