[Docket No. DHS 2016-0060]

National Protection and Programs Directorate

AGENCY: Office of Infrastructure Protection, National Protection and 
Programs Directorate, DHS.

ACTION: Study Participation; notice for voluntary participation 
regarding Positioning, Navigation, and Timing Study.


SUMMARY: The purpose of this notice is to inform the public that the 
Departmenet of Homeland Security (DHS) Science and Technology 
Directorate (S&T) and DHS National Protection and Programs Directorate 
(NPPD), Office of Infrastructure Protection (IP) are engaging critical 
infrastructure sector owners and operators in a study to define and 
validate current and future positioning, navigation, and timing (PNT) 
requirements for critical infrastructure. This study will be 
coordinated with the Department of Transportation, which is 
establishing PNT requirements for the transportation sector. The 
requirements defined and validated by the study will support key 
decisions in the development of complementary PNT solution(s).
    Accurate PNT is essential for critical infrastructures across the 
country. Currently, the Global Positioning System (GPS) is the primary 
source of PNT information. However, GPS signals are susceptible to both 
unintentional and intentional disruption leaving critical 
infrastructure vulnerable to operational impacts from disruptions. Due 
to the essential need for precise timing within many of the critical 
infrastructure sectors, DHS will initially focus the study on timing 
requirements within the electricity and wireless communications 
sectors. Subsequently, DHS will engage additional sectors and expand 
the study to include positioning and navigation requirements.

FOR FURTHER INFORMATION CONTACT: Organizations or individuals 
interested in providing PNT requirements or other information 
pertaining to the study should contact the points of contact below by
