  • Patent number: 10911931
    Abstract: An apparatus and method are disclosed to receive location data identifying the current location of a vehicle, for example an automobile or aircraft. A database, storing radio device records, is then queried. Each radio device record in the database identifies a radio device and its location. Radio device records associated with radio devices likely to be within communication range of the vehicle may then be retrieved from the database. The radio device records may be used to generate information for individual ones of radio devices which are likely to be within range of the vehicle and display that radio device information to a vehicle operator via an electronic display. The display may be updated as the vehicle travels to display radio device information as the radio devices come into range of the vehicle and remove radio device information from the display as the vehicle travels out of range.
