While the use of GNSS based time has become more vital for critical infrastructure operations, the security of the GNSS signal itself has become increasingly vulnerable to a wide range of jamming and spoofing threats, both intentional and unintentional. Given the inherently fragile nature of the GNSS signal, an important way Read more »
One of the big challenges to Protecting, Toughening, and Augmenting GPS is the huge number of GPS/GNSS receivers already in use — often referred to as “the installed base.” Read more »

Critical Infrastructure relies on position, navigation, and timing (PNT) which is now almost exclusively delivered using GNSS. The threat of GNSS errors has become Read more »
Cesium beam atomic clocks, such as Microsemi’s 5071A and TimeCesium products, have been popular frequency standards for deployment in Critical Infrastructure for many years. The cesium clock used in communications Read more »
When a GNSS failure occurs, dispatching personnel to a location to resolve an issue could take hours or even days. Critical Infrastructure operators rely on holdover clocks to provide valuable Read more »
GNSS-based errors, whether intentional or unintentional, can quickly impact a vast geography and widely dispersed locations. Additionally, a large variety of operational environments must be accounted for Read more »
Critical Infrastructure is typically constructed in a tiered manner beginning with a set of core sites that are connected Read more »
In recent articles, I’ve talked about ESMA’s MiFID II requirements and how this regulation – effective January 2018 – will require trading systems to time stamp key trading event records within an assured level of accuracy… Read more »
I’ve always appreciated the saying “a man with one clock knows the time, a man with two is not sure.” Read more »
