Techniques for providing evacuation guidance parameters to a vehicle traversing in a geographical region in the presence of interfering GNSS signals are disclosed. In some embodiments, a vehicle can determine evacuation guidance parameters from characteristics of at least one interfering source and implement evasive maneuvers based on the evacuation guidance parameters. Alternatively, a vehicle can send characteristics of at least one interfering source to a central processing system located remotely from the vehicle, and receive evacuation guidance parameters from the central processing system.

Determine a GNSS based position malfunction and further estimate an own-ship position when determining that the GNSS position may be inaccurate. The system of this disclosure may use information either from any one or more of internal navigation systems and external information sources to determine whether a GNSS based position for the own-ship may be inaccurate and to provide a pseudo position for the own-ship as an independent position source. The system of this disclosure may determine the existence of the GNSS malfunction based on independent position information.

A ground weather center may transmit information requests that carry at least one meteorological specific triggering command. An airborne system may translate the triggering command into detectable meteorological conditions and may arm the trigger(s) for specific weather sensors accordingly and downlink information upon the airborne system detects the triggering conditions. By using such a triggering command, the airborne system may be able transmit the same amount of valuable information with less bandwidth by reducing the number of redundant downlinked packets.
