Statement of the National Space-Based Positioning, Navigation, and Timing Executive Committee

September 9, 2022

The National Space-Based Positioning, Navigation, and Timing Executive Committee (EXCOM) appreciates the study by the National Academies of Science, Engineering and Medicine (NASEM) committee on the important topic of interference to GPS capabilities, including those critical to national, homeland, and economic security.

The EXCOM, co-chaired by the Deputy Secretaries of the Departments of Defense (DoD) and Transportation (DOT), and with membership from over a dozen Departments and Agencies, supports the stated National Policy goal to protect the spectrum environment that is currently used by GPS and its augmentations, including critical systems for Federal Government, the men and women of our Military Services, the economy, scientific advancements, and U.S. Critical Infrastructure.

The EXCOM agrees with the statements by DoD, and the National Telecommunications and Information Administration (NTIA) about the NASEM study.

The EXCOM will review this lengthy study more carefully but agrees with the statements that our Nation requires a solution that ensures continued operations of critical systems. The study confirms the GPS interference testing approach used by DoD and DOT, based on signal-to-noise ratio, when done properly, is the more comprehensive and informative. In addition, the EXCOM agrees with NASEM's assessment that the proposed mitigation and replacement measures are impractical, cost prohibitive, and possibly ineffective.

The EXCOM looks forward to continuing to work with Departments and Agencies across America on this complex and important issue.
