For the last two decades, reliance upon GPS/GNSS for positioning, navigation and timing (PNT) by civilian applications has been an overwhelming success, providing increasingly accurate and reliable PNT information everywhere for free. However, in recent years, malicious threats have emerged have exposed the Achilles heel of GPS/GNSS: Its weak power and unencrypted signal format leave it vulnerable to jamming and spoofing.

An American space company that specialized in the design, manufacture and launch of small- and medium-class space and rocket systems for military customers needed to synchronize multiple simulators at once.

Selecting the best Resilient PNT solution for military applications might seem complicated, but answering a few key questions can help define requirements. The most important objective is to ensure that trusted, accurate PNT data is available to warfighters so they can have confidence making decisions and can continue operations, even in contested or GPS denied environments.

These days, it’s easier than ever to disrupt GPS/GNSS signals and systems that rely on accurate Positioning, Navigation and Timing (PNT) data -- and nearly every critical system around the world depends on these signals and data. When it comes to military systems, failure isn’t an option. How can you protect essential systems from interference and denial of service attacks?

Network experts already know that distributing the correct time is key to maintaining their critical infrastructure programs. However, keeping accurate time is also fundamental to many cybersecurity applications. Over the last few years, there has been significant research into ways that the NTP protocol can be secured from malicious attackers.

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.
