The U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) is hosting the 2020 GPS Equipment Testing for Critical Infrastructure (GET-CI) event. This event will take place during the summer of 2020. The revised the due date for responses is May 8, 2020. Visit this site for more information. S&T’s GET-CI events are a series of annual evaluation events intended for manufacturers of commercial GPS equipment used in critical infrastructure as well as critical infrastructure owners and operators. DHS S&T recognizes the importance of accurate and precise position, navigation and timing (PNT) information to critical infrastructure and has a dedicated multi-year program to address GPS vulnerabilities in critical infrastructure, with a multi-pronged approach of conducting vulnerability and impact assessments, developing mitigations, exploring complementary timing technologies, and engaging with industry through outreach events and meetings. Through these sustained efforts, the goal of the program is to increase the resiliency of critical infrastructure to GPS vulnerabilities in the near-term future. Examples of measures that can be taken to enhance resiliency can be found in a DHS issued set of best practices released via ICS-CERT, titled “Improving the Operation and Development of Global Positioning System (GPS) Equipment Used by Critical Infrastructure.”
