SUBJECT: Space Policy Directive 7, The United States
Space-Based Positioning, Navigation, and Timing
Policy

This Space Policy Directive establishes implementation actions and guidance for United States space-based positioning, navigation, and timing (PNT) programs and activities for United States national and homeland security, civil, commercial, and scientific purposes. This policy complements the guidance set forth in Executive Order 13905 of February 12, 2020 (Strengthening National Resilience through Responsible Use of Positioning, Navigation, and Timing Services), and the intersector guidance for Global Navigation Satellite Systems (GNSS) included in the December 9, 2020, National Space Policy. This policy supersedes National Security Presidential Directive-39 (NSPD-39) of December 15, 2004 (United States Space-Based Positioning, Navigation, and Timing Policy).

Section 1. Scope. This policy directive provides guidance for:

(a) sustainment and modernization of the Global Positioning System (GPS) and federally developed, owned, and operated systems used to augment or otherwise improve GPS;

(b) implementation and operation of capabilities to protect United States and allied access to and use of GPS for national, homeland, and economic security, and to deny adversaries hostile applications use of United States space-based PNT services; and

(c) United States participation in international cooperative initiatives regarding foreign space-based PNT services and foreign use of GPS and its augmentations.

Sec. 2. Definitions. For purposes of this document:

(a) “PNT service” refers to 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) “Primary PNT Service” refers to an independent PNT service chosen by a user or system operator as the preferred source of PNT information. A primary PNT service is expected to provide sufficient accuracy, availability, integrity, or other characteristics important to the user.

(c) “Augmentation” refers to any system that provides users of PNT signals with additional information that enables users to obtain enhanced performance when compared to the un-augmented signals from a primary PNT service alone. These improvements include improved accuracy, availability, integrity, and reliability, and independent integrity monitoring and alerting capabilities for critical applications. Augmentation systems inherently rely on a primary PNT service to operate.

(d) “Alternative PNT Service” refers to a PNT service that has the capability to operate completely independent of, or in conjunction with, other PNT services. Multiple, varied PNT services used in combination may provide enhanced security, resilience, assurance, accuracy, availability, and integrity. An alternative PNT service allows a user to transition from the primary source of PNT signals in the event of a disruption or manipulation.

(e) “Interoperable” refers to the ability of multiple, independent PNT services and their augmentations to be used together to provide better capabilities at the user level than would be achieved by relying solely on a single service or signal.

(f) “Compatible” refers to the ability of multiple, independent PNT services and their augmentations to be used separately or in combination with each other without interfering with any individual service, and without adversely affecting the United States and allied military employment of PNT, commonly referred to as Navigation Warfare.

(g) “Navigation Warfare” or “NAVWAR” refers to the deliberate defensive and offensive action to assure and prevent positioning, navigation, and timing information through coordinated employment of space, cyberspace, and electronic warfare. Desired effects are generated through the coordinated employment of components within information operations, space operations, and cyberspace operations, including electronic warfare, offensive and defensive space operations, and computer network operations.

Sec. 3. Background. The multi-use services provided by GPS are integral to United States national security, economic growth, transportation safety, and homeland security. These services are essential but largely invisible elements of worldwide economic infrastructures.

(a) Responsible use of Space–Based PNT.

(i) GPS is a key component of multiple sectors of United States critical infrastructure, as identified in Presidential Policy Directive-21 (PPD-21) of February 12, 2013 (Critical Infrastructure Security and Resilience) and stated in EO 13905. Cascading effects from extended PNT service disruption or denial can adversely affect all sectors. Autonomous vehicles on land, sea, and air have begun to rely on GPS for navigation, positional awareness, and other vehicle capabilities. Additionally, many information systems rely on the GPS timing signal to enable both fixed and mobile communications. An extended outage of GPS, or extended period of spoofed or manipulated GPS signals, could cause severe economic losses and put lives at risk.

(ii) GPS remains critical to United States national security. Its applications are integrated into virtually every facet of United States military operations. United States and allied military forces will continue to equip and train for the responsible use of GPS and alternative PNT services to support mission operations.

(iii) The widespread and growing dependence on GPS by military, civil, and commercial applications, systems, and infrastructure make the performance of many of these systems inherently vulnerable if disruption or manipulation of GPS signals were to occur. GPS users must plan for potential signal loss and take reasonable steps to verify or authenticate the integrity of the received GPS data and ranging signal, especially in applications where even small degradations can result in loss of life. In addition, whether designed for military capabilities or not, signals from PNT services and their augmentations provide inherent capabilities that may be used by adversaries, including enemy military forces and terrorist groups.

(b) Space Applications. Applications for GPS now extend beyond Earth. The Terrestrial Service Volume of GPS, defined as the volume from the ground to an altitude of 3,000 kilometers, has become an integral component for space launch operations. Use of GPS is expanding into the Space Service Volume (SSV), which extends from 3,000 km to geosynchronous Earth orbit (GEO), despite reduced line-of-sight visibility and lower received signal power. Satellites rely on GPS for navigation, attitude control, space situational awareness, and new space science applications such as radio occultation. Consistent with Space Policy Directive-1 (SPD-1) of December 11, 2017 (Reinvigorating American’s Human Space Exploration Program) and Space Policy Directive-3 (SPD-3) of June 18, 2018 (National Space Traffic Management Policy) PNT services will also play an important role in space traffic management and future applications in the Cislunar Service Volume, which extends from GEO out to and including the Moon’s orbit. For requirements necessary to support these emerging applications, agencies should coordinate through standard GPS requirements processes.

(c) Foreign Space-Based PNT. Emerging foreign space-based PNT services could enhance or undermine the future utility of GPS. The United States will continue to encourage the development of foreign space-based PNT services based on GPS and their responsible use in non-military applications with allied and likeminded nations. Use of multiple, varied PNT services can result in better performance in terms of user accuracy, availability, and resilience. However, the United States Government does not assure the reliability or authenticity of foreign PNT services. Although foreign space-based PNT services may be used to complement civil GPS service, receiver manufacturers should continue to improve security, integrity, and resilience in the face of growing cyber threats. Thus, incorporation of foreign PNT in multi-constellation devices should be designed in a manner that precludes potential degradation of essential user capabilities resulting from possible foreign global navigation satellite system (GNSS) origins. The United States will maintain awareness of the risks and potential benefits associated with the use of foreign space-based PNT services and continue to promote and support the responsible use of GPS as the pre-eminent space-based PNT service.

(d) United States Policy and Management Framework.

(i) The United States continues to improve and maintain GPS and its augmentations to meet growing national, homeland, and economic security requirements as well as other civil requirements, and to enable diverse commercial and scientific applications. In parallel, the United States continues to improve capabilities to deny adversary access to space-based PNT services, particularly including services that are openly available and can be readily used by adversaries or terrorists, to threaten the security of the United States. The United States is addressing risks associated with dependence on space-based PNT and fostering responsible use approaches to PNT service acquisition, integration, and deployment across critical infrastructures. The United States is also encouraging the development of alternative approaches to PNT services and security that can incorporate new technologies and services as they are developed, such as quantum sensing, relative navigation and private or publicly owned and operated alternative PNT services.

(ii) The diverse requirements for and multiple applications of space-based PNT services require stable yet adaptable policies and management mechanisms. Therefore, the United States Government will continue to support a policy and management framework governing GPS and its augmentations that meets increasing and varied domestic and global requirements.

Sec. 4. Policy Goals and Guidance. The goal of this policy is to maintain United States leadership in the service provision, and responsible use of global navigation satellite systems, including GPS and foreign systems. To this end, the United States Government shall:

(a) Provide continuous worldwide access to United States space-based GPS services and government-provided augmentations, free of direct user fees, and provide open, free access to information necessary to develop and build equipment to use these services;

(b) Operate and maintain the Global Positioning System in accordance with United States law to satisfy civil, homeland security, and national security needs, consistent with published performance standards and interface specifications;

(c) Improve NAVWAR capabilities to deny hostile use of United States Government space-based PNT services, without unduly disrupting civil and commercial access to civil PNT services outside an area of military or homeland security operations;

(d) Improve the performance of United States space-based PNT services, including developing more robust signals that are more resistant to disruptions and manipulations consistent with United States and allied national security, homeland security, and civil purposes;

(e) Improve the cybersecurity of GPS, its augmentations, and United States Government owned GPS-enabled devices, and foster private sector adoption of cyber-secure GPS enabled systems through system upgrades and incorporation of cybersecurity principles for space systems, interface specifications, and other guidance that prescribes cybersecurity for user equipment;

(f) Protect the spectrum environment that is currently used by GPS and its augmentations, and work with United States industry to investigate additional areas of the radio spectrum which could increase GPS and PNT resilience;

(g) Invest in domestic capabilities and support international activities to detect, mitigate, and increase resilience to harmful disruption or manipulation of GPS, and identify and implement, as appropriate, alternative sources of PNT for critical infrastructure, key resources, and mission-essential functions;

(h) Maintain GPS and its augmentations for use by United States critical infrastructure to enhance safety of life functions and operational efficiency, consistent with PPD-21;

(i) Engage with international GNSS providers to
ensure compatibility, encourage interoperability with likeminded nations, promote transparency in civil service provision, and enable market access for United States industry. Encourage foreign development of PNT services and systems based on GPS and the inclusion of GPS as an essential element in systems that integrate multiple PNT services. At a minimum, seek to ensure that all foreign systems are compatible with GPS and its augmentations, that they do not interfere with GPS military and civil signals, and that mutual security concerns are addressed to prevent hostile use of United States space-based PNT services;

(j) Promote the responsible use of United States space-based PNT services and capabilities for applications at the Federal, State, and local level, consistent with Executive Order 13905; and

(k) Promote United States technological leadership in the provision of space-based PNT services and in the development of secure and resilient end user equipment.
