SYSTEM FOR PROVIDING LOCATION-SPECIFIC DATA TO A USER |
| abstract |
An FDMA/TDM satellite-based broadcast system is used to provide digital maps (120) and other type of data to users at remote locations. User selection of the desired data is achieved by monitoring the TDM downlink channels (30) of the broadcast system in accordance with a specific schedule or until a specific identification code is detected. The user terminals (22) are equipped with Global Positioning System receivers (84) which allow the position of the users to be determined. Based on the user position, the user terminal (22) are able to convert general data to location-specific data tailored to the need of the user. The general data may comprise a digital map covering a wide geographic area, and the location-specific data may comprise a map (120) covering a portion of the geographic region where the user is located. |
