GPS Spoofing
GPS spoofing is an attack where an adversary broadcasts fake GPS signals to trick a receiver into calculating an incorrect position or time. This can cause autonomous vehicles like drones or ships to go off course without realizing it.

TECHNICAL DEFINITION
GPS spoofing is a navigation warfare (NAVWAR) technique involving the transmission of counterfeit Global Navigation Satellite System (GNSS) signals to subvert a receiver's Positioning, Navigation, and Timing (PNT) data. This electronic attack is used to misdirect autonomous systems, such as UAVs, guided munitions, and maritime vessels, by creating a false perception of location and time.
BACKGROUND
The Global Positioning System (GPS) is a satellite-based hyperbolic navigation system owned by the United States Space Force and operated by Mission Delta 31. It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where signal quality permits. It does not require the user to transmit any data, and operates independently of any telephone or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls, and maintains GPS, it is freely accessible to anyone with a GPS receiver.

USAGE NOTE
Spoofing is considered a more deceptive and insidious electronic attack than jamming because the target system often doesn't know it's being manipulated.
DEVELOPERS
Organizations developing technology related to GPS Spoofing.
A major defense contractor that develops advanced military-grade GPS receivers, such as the Digital GPS Anti-Jam Receiver (DIGAR), which incorporate sophisticated anti-spoofing and anti-jamming technologies to ensure position, navigation, and timing (PNT) assurance in contested environments.
A global aerospace and defense technology company that produces a wide range of secure PNT solutions for military applications. Their products include advanced GPS user equipment with anti-spoofing and anti-jamming capabilities designed to operate reliably in the presence of electronic warfare threats.
Formerly Raytheon Technologies, RTX develops and manufactures next-generation GPS user equipment for the military. Their work focuses on creating more secure and resilient navigation systems that can detect, mitigate, and operate through GPS spoofing and jamming attacks.
As the prime contractor for the U.S. Space Force's GPS III and GPS IIIF satellite constellations, Lockheed Martin is directly involved in developing the source of spoofing-resistant signals. These satellites broadcast the more powerful and encrypted M-Code signal, a key element in countering spoofing.
A leading provider of test and measurement solutions for PNT systems. Spirent develops sophisticated GNSS simulators that can generate complex spoofing and jamming scenarios, allowing military and civilian developers to test and validate the resilience of their GPS receivers.
A world leader in resilient PNT solutions. Orolia develops technology, including interference detection and mitigation (IDM) systems like BroadShield, which are designed to protect critical infrastructure and military assets from GPS/GNSS spoofing and jamming attacks.
A key government research organization that pioneers advanced navigation technologies. AFRL conducts research into detecting and mitigating GPS spoofing, develops alternative navigation systems for GPS-denied environments, and works on improving the security and resilience of military PNT capabilities.
A company specializing in securing GNSS signals from spoofing attacks. They develop software-based solutions that can detect and mitigate spoofing for a variety of applications, including drones, vehicles, and defense systems, by validating the authenticity of the GPS signal itself.
