GPS Spoofing Solution
Tips For Protecting Aviation Industry Against GPS Spoofing
Attacks:
Obscure or hide real antennas. Make sure the commercial aviation are not visible to the public
by installing barriers or putting them in a place where they will not be seen.
Choose the location antennas carefully. They will need a clear view of the sky, but it can be
wise to ensure that they are blocked from public locations and nearby buildings.
Install decoy antennas. Make these antennas clearly visible and put them at least 300 meters
away from your real ones.
Add redundant antennas. Having more than one antenna in a slightly different location can help
companies to spot potential issues quickly.
Use blocking antennas. These work to protect against jamming and interference. They can also
lower the risk for spoofing attacks.
Use backups. Inertial sensors can help to determine actual position and cesium, or rubidium
clocks can work as backup timing systems when GPS is down. Backup systems that do not rely
on GPS are helpful in the event of an issue.
Practice good cyber hygiene. When not needed for network connectivity, GPS receivers and
associated equipment should be kept offline. Two-factor authentication should be in place,
passwords changed often, and updates and patches installed regularly. Virus protection,
firewalls, and cyber defense practices should all be implemented.
