IEEE (Institute of Electrical and Electronics Engineers) Working Group for Resilient User Equipment in Positioning, Navigation, and Timing (P1952)

Positioning, navigation, and timing (PNT) technologies are integral to numerous applications, including critical infrastructure. Notably, GPS (Global Positioning System) and other satellite-based navigation systems (satnav) offer globally accessible, low-cost, precise PNT services with such high reliability that their utility is often taken for granted. However, these systems are susceptible to various adversities, both accidental and intentional, such as interference, spoofing, and cyber-attacks. In response to growing concerns regarding the security of PNT technologies, the IEEE (Institute of Electrical and Electronics Engineers) Standards Association established the P1952 working group to develop standards for resilient PNT user equipment. The P1952 standard aims to classify the resilience of PNT user equipment by defining discrete levels of increasing resilience. This standard emphasizes the input and output interfaces of PNT user equipment, stipulating requirements for the equipment's ability to adapt its output behavior in response to adversities encountered at its input interfaces. To facilitate efficient testing for compliance, P1952 has categorized these adversities. The working group has initiated collaboration with the IEEE Conformity Assessment Program (ICAP) to promote the development of testing protocols. Additionally, P1952 has been rigorously examining representative use cases from various industries, including critical infrastructure. The officers of the P1952 working group will present the current status of the standard, the development process, and an overview of the final stages of their work.
