Abstract:
Global Navigation Satellite Systems (GNSS) such as the Global Positioning System (GPS) have made cost effective, highly precise, positioning, navigation, and timing (PNT) available globally. This has led to the routine use of GNSS-derived PNT information in a wide variety of infrastructure including energy generation and distribution, communications, finance, transportation, broadcast, manufacturing, defense, and others. The ubiquitous use of GNSS receivers in critical infrastructure has raised concerns about the vulnerability of GNSS to disruptions, either malicious or accidental. Indeed, there are numerous reports of failures of GNSS receivers due to equipment failures or damage, unintentional radio interference, and GNSS constellation system errors. Even more alarming is the increasing number of reports of malicious jamming or spoofing of GNSS. The IEEE Standards Association has responded to this concern by creating the P1952 working group for Resilient Positioning, Navigation, and Timing User Equipment Working Group. The working group has begun the process of defining levels of resilience for PNT user equipment that can be used to indicate user equipment’s ability to withstand disruptions or recover from disruptions. Officers of the working group will present the plans for organizing the standard, the process for developing it and progress to date.
