Abstract
An electronic device such as a cellular telephone, for example, includes a receiver that receives broadcast radio signals transmitted by a commercial broadcast radio station. The broadcast radio signals include information that identifies a location of the radio station, an antenna associated with the radio station, or the radio station. The device also includes positioning circuitry to allow the device to determine its current location. A controller in the device extracts the information identifying the radio station from the received broadcast signal, and acquires one or more satellites of a navigational system based on the information.
Claims26
An electronic device comprising:
- a receiver to receive a broadcast radio signal transmitted by a broadcast radio station, the broadcast radio signal including identifying information associated with the broadcast radio station;
- a controller to determine a reference location based on the identifying information received from the broadcast radio station;
- and
- a positioning circuit to acquire one or more satellites of a navigational system based on the determined reference location.
A method of obtaining navigational assistance data at an electronic device, the method comprising:
- receiving a broadcast radio signal at the electronic device, the broadcast radio signal comprising identifying information associated with a broadcast radio station transmitting the broadcast radio signal;
- determining a reference location based on the identifying information included with the broadcast radio signal;
- and
- acquiring one or more satellites of a navigational positioning system based on the reference location.
