As is widely understood, GPS signals are weak and vulnerable to interference. Interference can be unintentional, such as side band energy from radio transmissions on the battlefield, or intentional. Intentional interference can be jamming or it can be a fake signal, sometimes called spoofing or sophisticated jamming. Spoofing is potentially the most dangerous type of interference. Connectivity and signal disruption is one issue; acting on misinformation or falsified data could be catastrophic.

Today's time sensitive networks rely on available and accurate positioning, navigation and timing (PNT) signals to provide leaders with the information required to make timely and effective decisions. The proliferation of GNSS-degrading and denying devices across state and non-state actors put this critical information capability in jeopardy. Learn how a combination of alternative PNT signals with traditional GNSS references makes PNT applications resilient against jamming and spoofing.

While the use of GNSS – more commonly known as GPS – is now widespread, the signal itself comes from satellites that are 20,000 kilometers away, making it fairly weak and subject to loss of signal or interference. For military operations, this presents several challenges. In a recent naval exercise, a scenario of GPS denial triggered up to 48 shipboard systems to generate alerts when GPS was lost. This shows how GPS is so pervasive and deeply integrated into many military systems for air, land and sea.

More than 2,000 billion Euros of critical infrastructures around the world are directly dependent upon GPS every day – including public and private, aerospace and defense, smart cities, IoT, finance, industry, automotive, ITS, mobility, broadcast and telecom, and Cloud. All benefit from this accurate and trustable PNT service to support their operations.

In 2013, the Federal Communications Commission fined a person almost $32k for using a device intended to evade the fleet management tracking system on his company vehicle. The device in question: a GPS jammer.

Cybersecurity is a popular topic in the news today, but Position, Navigation, and Timing (PNT) security does not get the same attention. But like cyberattacks, attacks against GPS or other global navigation satellite system (GNSS) systems can have profound and damaging effects on critical infrastructure, financial institutions, and military capabilities.

Today’s critical infrastructure, including many military systems, rely on GPS for position, navigation and timing (PNT) reference. But what happens when GPS is lost or corrupted? How can alternative PNT signals support critical capability in this situation?

For military personnel, keeping sight of the enemy can mean the difference between life and death. Military leaders frequently emphasize their need for reliable and accurate positioning, navigation and timing (PNT) systems. Accurate PNT is critical for their communications, sensors, network systems, and search and rescue missions.
