Tech Brief Resiliency in PNT: Cybersecurity

Print

Cybersecurity is the watchword of the day, but what does it mean for Positioning, Navigation and Timing (PNT)? For many, the ability to hack or spoof a GPS/GNSS signal is a cybersecurity issue. At Orolia, we agree, which is why we have a wide array of products to augment, toughen and protect against GNSS vulnerabilities.

However, the other aspect is network connectivity. Any device that is on a network – which includes many PNT devices – must address cybersecurity.

This Orolia Tech Brief explores the basic steps for maintaining security using a network-connected time server and looks at different ways to achieve resiliency in PNT. As an example, we will start with our SecureSync® Time Server product line to demonstrate how to maintain security with this network-connected device.
