Abstract: An RF interference database provides RF signal characteristics associated with a plurality of geographical locations. A travel planning system on a vehicle or other processing system can disseminate data including the RF signal characteristics to multiple operating systems on at least one vehicle in a network. Disseminating data can include generating a report sent to the operating system(s), generate threat levels and/or alerts based on the severity of RF interference in the geographical location, provide a system use recommendation on operating parameters and/or alternative operating systems for use in the geographical location. A vehicle can also take ameliorative action, such as modifying a travel path based on data disseminated from the RF interference database and/or conduct integrity checks on the operating systems.
