Over the last few years, jamming and spoofing have been clearly identified as a major GNSS cybersecurity risk. High-end GNSS testing technologies and risk mitigation solutions have been deployed and enhanced for a growing number of Aerospace, Defense and Government (ADG) applications ... but only recently has anyone been thinking about them specifically for commercial infrastructure.

Cybersecurity is a hot topic today. Hackers are always looking to undermine our network connections and we are always trying to protect against them. I’m no cybersecurity expert, but I am often asked, “Can Resilient PNT be used to improve cybersecurity?” Resoundingly, “yes.” Here are a few simple examples.

Whether in the air, on land, or at sea, vehicles will impart shocks and vibrations to their electronics, sometimes severely. In high vibration environments, the system designer must account for induced phase noise which can drastically affect overall performance. This white paper discusses the challenges of keeping low noise signals pure in any environment.

Network time service is not something many businesses think about as a key component of their critical infrastructures. In fact, it is often overlooked entirely, and in error. As a result, the network architect or engineer often defaults to an easy alternative: using a server or network switch as the source of the network clock and synchronizing these sources to Internet time servers using Network Time Protocol (NTP). This white paper discusses the risks of, and alternative solutions to, "NTP Over the Internet."

Maintaining a state of military readiness is a top priority for defense agencies. The ideal approach would deliver a consistent solution that is cost-effective across different platforms, with the ability to provide a compatible, scalable system to all of them. Expensive, inflexible A-PNT solutions will not solve the total problem. To provide affordable A-PNT for every link in the communications chain, a different approach is needed.

To improve performance of your radar system or signal intelligence (SIGINT) receiver, you need a time and frequency reference that can deliver a low phase noise signal. If your mission is signal intelligence gathering, then that means deeper penetration and more intelligence gathered.

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.
