1. A method, comprising:
receiving at least one characteristic of at least one source radiating signals in at least one geographical region in which a vehicle is traversing, wherein the at least one characteristic includes an azimuth parameter of the at least one source and is received in response to a determination that the radiating signals from the at least one source interfere with operation of at least one global navigation satellite systems (GNSS) receiver associated with the vehicle, and wherein the azimuth parameter is identified based on a change of a heading of the vehicle; and
sending, in response to the received at least one characteristic of the at least one source, a message to one or more systems on the vehicle, the message including evacuation guidance parameters for evacuating the at least one geographical region due to the interference of the at least one GNSS receiver from the at least one source during a period of time in which the vehicle is inside the at least one geographical region.
