By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered as follows:

Section 1.  Purpose.  The national and economic security of the United States depends on the reliable and efficient functioning of critical infrastructure.  Since the United States made the Global Positioning System available worldwide, positioning, navigation, and timing (PNT) services provided by space-based systems have become a largely invisible utility for technology and infrastructure, including the electrical power grid, communications infrastructure and mobile devices, all modes of transportation, precision agriculture, weather forecasting, and emergency response.  Because of the widespread adoption of PNT services, the disruption or manipulation of these services has the potential to adversely affect the national and economic security of the United States.  To strengthen national resilience, the Federal Government must foster the responsible use of PNT services by critical infrastructure owners and operators.

Sec. 2.  Definitions.  As used in this order:

(a)  “PNT services” means any system, network, or capability that provides a reference to calculate or augment the calculation of longitude, latitude, altitude, or transmission of time or frequency data, or any combination thereof.

(b)  “Responsible use of PNT services” means the deliberate, risk-informed use of PNT services, including their acquisition, integration, and deployment, such that disruption or manipulation of PNT services minimally affects national security, the economy, public health, and the critical functions of the Federal Government.

(c)  “Critical infrastructure” means systems and assets, whether physical or virtual, so vital to the United States that the incapacity or destruction of such systems and assets would have a debilitating impact on national security, national economic security, national public health or safety, or on any combination of those matters.

(d)  “PNT profile” means a description of the responsible use of PNT services — aligned to standards, guidelines, and sector-specific requirements — selected for a particular system to address the potential disruption or manipulation of PNT services.

(e)  “Sector-Specific Agency” (SSA) is the executive department or agency that is responsible for providing institutional knowledge and specialized expertise as well as leading, facilitating, or supporting the security and resilience programs and associated activities of its designated critical infrastructure sector in the all-hazards environment.  The SSAs are those identified in Presidential Policy Directive 21 of February 12, 2013 (Critical Infrastructure Security and Resilience).

Sec. 3.  Policy.  It is the policy of the United States to ensure that disruption or manipulation of PNT services does not undermine the reliable and efficient functioning of its critical infrastructure.  The Federal Government must increase the Nation’s awareness of the extent to which critical infrastructure depends on, or is enhanced by, PNT services, and it must ensure critical infrastructure can withstand disruption or manipulation of PNT services.  To this end, the Federal Government shall engage the public and private sectors to identify and promote the responsible use of PNT services.

Sec. 4.  Implementation.  (a)  Within 1 year of the date of this order, the Secretary of Commerce, in coordination with the heads of SSAs and in consultation, as appropriate, with the private sector, shall develop and make available, to at least the appropriate agencies and private sector users, PNT profiles.  The PNT profiles will enable the public and private sectors to identify systems, networks, and assets dependent on PNT services; identify appropriate PNT services; detect the disruption and manipulation of PNT services; and manage the associated risks to the systems, networks, and assets dependent on PNT services.  Once made available, the PNT profiles shall be reviewed every 2 years and, as necessary, updated.

(b)  The Secretary of Defense, Secretary of Transportation, and Secretary of Homeland Security shall refer to the PNT profiles created pursuant to subsection (a) of this section in updates to the Federal Radionavigation Plan.

(c)  Within 1 year of the date of this order, the Secretary of Homeland Security, in coordination with the heads of SSAs, shall develop a plan to test the vulnerabilities of critical infrastructure systems, networks, and assets in the event of disruption and manipulation of PNT services.  The results of the tests carried out under that plan shall be used to inform updates to the PNT profiles identified in subsection (a) of this section.

(d)  Within 90 days of the PNT profiles being made available, the heads of SSAs and the heads of other executive departments and agencies (agencies), as appropriate,…
