NATIONAL AERONAUTICS AND SPACE ADMINISTRATION

CHARTER OF THE

NATIONAL SPACE-BASED POSITIONING, NAVIGATION, AND TIMING

ADVISORY BOARD

1. Official Designation: National Space-Based Positioning, Navigation, and Timing Advisory 

Board (“PNT Advisory Board”).

2. Authority: The National Space-Based Positioning, Navigation, and Timing Advisory Board 

was established pursuant to the National Security Presidential Directive-39 (NSPD-39) of 

December 15, 2004, and most recently continued by Executive Order 14048 of September 30, 

2021. On January 15, 2021, Space Policy Directive 7 (SPD-7), “The United States Space-Based 

Positioning, Navigation, and Timing Policy,” superseded NSPD-39 of December 15, 2004. The 

PNT Advisory Board operates in accordance with the provisions of the Federal Advisory 

Committee Act (FACA), 5 U.S. Code 10.

3. Objectives and Scope of Activities: SPD-7 establishes implementation actions and guidance 

for United States (U.S.) space-based positioning, navigation, and timing (PNT) programs and 

activities for U.S. 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 inter sector guidance for Global Navigation Satellite Systems (GNSS) 

included in the December 9, 2020, National Space Policy. SPD-7 reaffirms the role of the 

National Space-Based Positioning, Navigation, and Timing Executive Committee (“PNT 

EXCOM”) as the interagency body responsible for guiding and preserving whole-of-Government 

interests in the provision of space-based PNT services, augmentations, and space-based 

alternatives. SPD-7 also directs the PNT EXCOM to maintain and receive advice from the 

National Space-Based Positioning, Navigation, and Timing Advisory Board (“PNT Advisory 

Board”), established by NSPD-39 and continued by the Executive Order 14048, “Continuance or 

Reestablishment of Certain Federal Advisory Committees and Amendments to Other Executive 

Orders.” The National Aeronautics and Space Administration (NASA), in close coordination 

with the PNT EXCOM, will task the PNT Advisory Board and define the full scope of activities 

and schedules required to accomplish such tasks based on emerging national and international 

PNT developments. The PNT Advisory Board will operate solely in an advisory capacity as 

directed by the U.S. PNT Policy and in accordance with FACA, 5 U.S. Code 10.

4. Description of Duties: The PNT Advisory Board shall be composed of experts from outside 

the U.S. Government and shall be chartered as a Federal Advisory Committee. The Advisory 

Board shall seek input from state and local governments, industry, and academia on 

developments in the application of space-based PNT technologies and advise the PNT EXCOM 

Committee on policy and service impacts. At the request of the EXCOM, NASA sponsors the 

PNT Advisory Board as part of NASA’s contribution towards PNT Policy implementation. The 
2

PNT Advisory Board will provide advice, as requested by the PNT EXCOM and through NASA, 

on U.S. PNT Policy, planning, program management, and funding profiles in relation to the 

current state of national and international space-based PNT services. This advice will consist of 

assessments and recommendations to facilitate the accomplishment of the goals and objectives of 

the U.S. PNT Policy on behalf of the PNT EXCOM. The PNT Advisory Board will evaluate 

national and international needs for changes in space-based PNT capabilities, assess possible 

trade-offs among options, and provide independent advice and recommendations to the PNT 

EXCOM on requirements and program needs. The U.S. reserves the right to hold “U.S. 

members-only” meetings of the PNT Advisory Board, as required, in full compliance with the 

FACA and related U.S. statutes and regulations.

5. Official to Whom the Committee Reports: The PNT Advisory Board will report findings, 

recommendations, and tasking progress to the PNT EXCOM, of which NASA is a member.

6. Support: The NASA Space Operations Mission Directorate shall provide staff support and 

operating funds for the PNT Advisory Board and is responsible for fulfilling the reporting 

requirements of section 7(b) of FACA.

7. Estimated Annual Operating Costs and Staff Years: The estimated annual operating costs 

are $150,000, which includes the approximate costs for meeting logistics, travel, report 

generation, subordinate meetings, and NASA staff support. NASA staff support is expected to 

require 0.3 work years of effort.

8. Designated Federal Officer: The Executive Director of the PNT Advisory Board shall be 

appointed by the NASA Administrator and will serve as the Designated Federal Officer (DFO). 

The DFO will be a full-time employee, who will: call, attend, and adjourn committee and 

subcommittee meetings; approve agendas; maintain required records on costs and membership; 

ensure efficient operations; maintain records for availability to the public; and provide copies of 

committee reports to the NASA Committee Management Officer for forwarding to the Library of 

Congress. The DFO will also coordinate with the PNT Advisory Board members and NASA's 

Office of General Counsel (OGC) to ensure that all legal/ethical requirements are met. With 

regard to Special Government Employees (SGEs), these requirements include, though are not 

limited to, timely filing of financial disclosure reports and ethics training by a representative of 

NASA’s OGC and seeking advice from the NASA OGC Ethics Team for any questions 

concerning Government ethics requirements that may arise.

9. Estimated Number and Frequency of Meetings: The PNT Advisory Board will meet 

approximately one to two times each fiscal year. Meetings will be open to the public unless it is

determined that the meeting, or a portion of the meeting, will be closed in accordance with the 

Government in the Sunshine Act, 5 U.S. Code 552b(c).

10. Duration: The duration of the PNT Advisory Board is continuing, subject to the 

Termination section below.

11. Termination: The PNT Advisory Board shall terminate on September 30, 2023, unless

continued by the President.

FACA as amended.

6. The PNT EXCOM may maintain a list of approved PNT Advisory Board nominees to fill 

vacancies and to enable rotation of new members onto the PNT Advisory Board at the 

discretion of the PNT EXCOM Co-Chairs and NASA Administrator.

7. Any PNT Advisory Board member rotations shall not exceed six members in any oneyear period to ensure a core institutional membership is maintained so as to ensure 

ongoing PNT Advisory Board work is not adversely affected.

8. The NASA Administrator, in consultation with the PNT EXCOM Co-Chairs, will 

designate the PNT Advisory Board Chair and Vice-Chair.

13. Subcommittees, and Task Forces: As authorized by the DFO, the PNT Advisory Board 

work may be organized and supported by subcommittees, and/or task forces, to ensure taskings 

are appropriately completed in a timely manner in consultation with the PNT Board Chair or 

Vice Chair. Subcommittees must report back to the parent committee and must not provide 

advice or work products directly to the Agency. In addition, NASA may authorize consultants 

with special expertise to support such subordinate groups on an ad hoc basis. Such 

subcommittees, and/or task forces, will be comprised of appointed PNT Advisory Board 

members and will report their findings and recommendations to the PNT Advisory Board Chair 

or Vice-Chair. Information classified for national security reasons may be provided to 

appropriately cleared members of the PNT Advisory Board to support the mission of the PNT 

EXCOM.

14. Recordkeeping: The records of the PNT Advisory Board, its subcommittees, and/or task 

forces, shall be handled in accordance with the General Record Schedule 6.2, or other approved 

Agency records disposition schedule. These records shall be available for public inspection and 

copying, subject to the Freedom of Information Act, 5 U.S.C. 552.
