1/18/2021 Memorandum on Space Policy Directive 7 | The White House 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 Tra ic Management Policy) PNT services will also play an important role in space tra ic 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 https://www.whitehouse.gov/presidential-actions/memorandum-space-policy-directive-7/ 6/24
