The House Armed Services Committee has inserted a provision into its fiscal year 2027 National Defense Authorization Act markup that would dismantle the existing multi-agency council overseeing the Pentagon’s positioning, navigation, and timing enterprise and replace it with a single, Senate-confirmed official reporting directly to the Deputy Secretary of Defense. The language is blunt in its diagnosis: despite years of reform efforts, the Department of Defense’s GPS and PNT programs continue to suffer from “a concerning lack of clear direction and sense of urgency.” The full committee is scheduled to formally mark up the bill on June 4 — the same day the House Energy and Commerce Committee holds a separate hearing titled Where Are We?: Examining Positioning, Navigation, and Timing Capabilities in the United States. The convergence of both events on a single day signals that GPS and PNT resilience have reached a rare moment of genuine congressional attention.
Background: A Governance Structure That Has Failed Its Mission
To understand why Congress is acting, it is necessary to understand how the current system works — and why it has not.
The United States’ national PNT governance structure was established in 2004 under National Security Presidential Directive 4 (NSPD-4) and updated only marginally by Space Policy Directive 7 (SPD-7) in January 2021. Under this framework, responsibility for PNT is divided between the Department of Defense (for military users) and the Department of Transportation (for civil users), with cross-departmental issues handled by a National Space-Based PNT Executive Committee co-chaired by the deputy secretaries of both departments.
Inside DoD, the architecture is even more diffuse. The Chief Information Officer serves as the Secretary’s principal staff assistant for PNT — but PNT is only one of dozens of CIO responsibilities. Below the CIO sits the DoD PNT Oversight Council, a body of nineteen senior leaders including service secretaries, combatant commanders, undersecretaries, and intelligence chiefs. These are among the most senior and most time-constrained officials in the federal government. The council advises the Deputy Secretary and Secretary of Defense.
The HASC provision would abolish this council entirely. In its place, the bill would require the Secretary of Defense, in consultation with the Chairman of the Joint Chiefs of Staff, to designate a single official as the principal authority for the DoD PNT enterprise — including alternative PNT programs alongside GPS — reporting directly to the Deputy Secretary of Defense.
The committee’s rationale is stated plainly in the legislative text: “The committee recognizes that despite previous efforts to improve oversight and execution of the PNT programs of the department, there remains a concerning lack of clear direction and sense of urgency to address existing gaps and plan for both near term and future requirements. Position, navigation, and timing is foundational to everything the joint force does, but despite this it continues to be plagued by a lack of senior oversight.”
The Accumulating Evidence of Failure
The committee’s frustration is not without basis. The record of DoD PNT mismanagement over the past decade is extensive.
The OCX Debacle. The most visible failure is the cancellation, in April 2026, of the Next Generation Operational Control System (OCX) — the program intended to modernize command and control of the GPS satellite constellation. RTX (formerly Raytheon) received the contract in 2010 with a planned delivery date of 2016. Instead, the program experienced a Nunn-McCurdy cost breach that same year, persistent software failures, and repeated schedule slippages. By the time the Space Force formally terminated the contract in April 2026, OCX had consumed approximately $6.27 billion — nearly double its original $3.7 billion estimate — and had still not achieved operational capability. Col. Stephen Hobbs, Mission Delta 31 commander, stated that “the challenges of onboarding the system in an operationally relevant timeline proved insurmountable” and that problems spanned “a broad range of capability areas that would put current GPS military and civilian capabilities at risk.” The Space Force is now upgrading the existing Architecture Evolution Plan (AEP) ground system, with Lockheed Martin awarded a $105 million contract for continued modernization.
User Equipment Out of Phase. The HASC markup notes that “user equipment is consistently out of phase with the space segment because of lack of prioritization by the services.” GPS III satellites, which carry modernized signals including the military M-code and the civilian L5 signal, have been launching since 2018. Yet the military user equipment capable of receiving those signals has not kept pace, leaving warfighters dependent on receivers that cannot exploit the newer, more resilient signals the constellation now broadcasts.
Launch Backlog. The space segment itself only recently cleared a backlog of unlaunched GPS satellites caused by launch vehicle delays — a problem that compounded the user equipment gap by creating uncertainty about when new signal capabilities would even be available.
A Pattern of GAO Warnings Ignored. A 2022 GAO report called for more coherent DoD PNT leadership. That report was, as RNTF President Dana Goward has noted, the third such GAO report in just fifteen months — a remarkable frequency that itself speaks to the depth of the problem and the failure of prior recommendations to produce change.
The Competitive Context: GPS Is No Longer the World’s Best
The governance failures have occurred against a backdrop of accelerating competition from peer adversaries. China’s BeiDou constellation is now widely assessed to have surpassed GPS in several key dimensions: newer satellites, more signals, higher accuracy in the Asia-Pacific region, and — critically — a complementary terrestrial backup system that provides resilience against space-segment disruption. Europe’s Galileo has achieved sub-meter accuracy with its High Accuracy Service (HAS) and offers 20-centimeter horizontal accuracy — a capability GPS does not match.
The United States, by contrast, has no deployed alternative or backup to GPS. A 2004 presidential mandate for such a system stood until 2021, when it was quietly removed. Senior officials in the current administration have cited the need for resilient PNT, but no funded program exists to deliver it. The HASC provision addresses only the governance structure inside DoD — it does not create a national backup PNT architecture, fund one, or establish a timeline for one.
The Provision’s Scope — and Its Limits
The proposed legislation would do three things. First, it would abolish the DoD PNT Oversight Council and replace it with a single designated official. Second, it would require that official to report directly to the Deputy Secretary of Defense — placing PNT at a higher level of the departmental hierarchy than it currently occupies. Third, it would require the designated official to certify annually that the service budgets are fully funding both user equipment and ground control systems for the PNT enterprise — a direct legislative check on the chronic under-prioritization the committee identified.
The annual certification requirement is potentially the most consequential element. It creates a named official who must go on record each year attesting that the services are adequately funding PNT. If they are not, the certification cannot be made — and the failure becomes visible. This is a meaningful accountability mechanism that the existing council structure lacks.
However, the provision has significant limitations that the RNTF and other observers have been quick to note.
Legislation alone does not fix things. The most instructive precedent is the Cruz-Markey National Timing Resilience and Security Act of 2018, which required the Department of Transportation to establish at least a terrestrial timing system to back up GPS. The law was passed. Nothing happened. Subsequent presidential budget requests have repeatedly sought its repeal. A law requiring action is not the same as action.
The civilian economy remains exposed. Even if the HASC provision survives the full markup, is enacted into law, and produces a genuinely empowered PNT official inside DoD, it addresses only the military’s internal governance. The far larger vulnerability — GPS signals underpinning virtually every sector of the American economy, from financial markets and power grids to aviation and telecommunications — remains entirely unaddressed. As Goward has written: “If this legislation does improve things for DoD PNT, it will do nothing for the nation’s greatest area of risk.”
The designated official still does not exist. The provision requires the Secretary of Defense to designate someone. It does not create a new position, fund a staff, or specify qualifications. The quality and authority of the resulting official will depend entirely on how seriously the Secretary takes the mandate.

The June 4 Convergence
The simultaneous occurrence of the HASC full committee markup and the House Energy and Commerce subcommittee hearing on June 4 is not coincidental — it reflects a broader congressional recognition that PNT has become a genuine national security and economic vulnerability that can no longer be deferred.
The Energy and Commerce hearing is particularly significant because it is being held by the Communications and Technology Subcommittee, which oversees the Federal Communications Commission. The FCC has been drawn into the PNT debate through competing petitions: NextNav is seeking approximately $5 billion in spectrum in exchange for establishing a terrestrial timing system to back up GPS, while the National Association of Broadcasters has proposed a Broadcast Positioning System. The FCC issued a 27-page Notice of Inquiry on PNT and received over 140 responses. The June 4 hearing will feature executives from NextNav, the GPS Innovation Alliance, the Consumer Technology Association, Public Knowledge, and the NAB.
The witness list and the FCC’s involvement suggest that the commercial and regulatory dimensions of GPS resilience — not just the military dimension — are now squarely on the congressional agenda. The HASC provision and the Energy and Commerce hearing together represent the most sustained congressional attention to PNT since the Cruz-Markey Act of 2018.
Analysis: Why This Matters for Defense Industry
For defense industry professionals, the HASC provision and the surrounding legislative activity carry several practical implications.
A new senior buyer is coming. If the provision is enacted and the Secretary of Defense designates a credible, empowered PNT official, that official will need to develop a strategy, establish requirements, and — critically — certify that service budgets are funding user equipment and ground control systems. This creates a new senior acquisition authority with both the mandate and the accountability to drive PNT modernization. Firms in GPS receiver modernization, alternative PNT (eLoran, fiber timing, pseudolite, LEO-PNT), and ground control systems should begin engaging now.
The ground segment is open. The OCX cancellation leaves a genuine capability gap in GPS ground control modernization. The Space Force’s pivot to AEP and Lockheed Martin’s $105 million contract is a bridge, not a destination. The longer-term question of how to modernize GPS ground control for GPS IIIF satellites and beyond remains unanswered. This is a significant opportunity for firms with ground segment, software-defined radio, and cybersecurity capabilities.
Alternative PNT is moving from advocacy to acquisition. The HASC language explicitly includes “alternative position, navigation, and timing efforts” within the new official’s mandate. Combined with the FCC’s active inquiry and the Energy and Commerce hearing, the policy environment for alternative PNT — terrestrial, fiber-based, LEO-based, and broadcast — is more favorable than it has been in years. The question is whether the legislative and regulatory activity will translate into funded programs.
The annual certification is a forcing function. The requirement for the designated official to certify annually that service budgets are fully funding PNT user equipment and ground control systems creates a recurring, public accountability mechanism. If services are under-funding these programs — as the HASC language implies they have been — the certification requirement will either force budget corrections or create a documented record of non-compliance. Either outcome is useful for industry: the former creates procurement opportunities, the latter creates political pressure for supplemental funding.
What to Watch
- June 4, 2026: HASC full committee markup of the FY27 NDAA. Whether the PNT provision survives intact, is amended, or is stripped will be the first major indicator of how seriously Congress intends to pursue this reform.
- June 4, 2026: House Energy and Commerce subcommittee hearing on PNT capabilities. Witness testimony — particularly from NextNav and the GPS Innovation Alliance — will signal where commercial and regulatory momentum is heading.
- FY27 NDAA floor and conference: Even if the provision passes committee, it must survive the full House, Senate Armed Services Committee markup, and conference. The Senate’s position on PNT governance reform is not yet known.
- DoD response: Whether the Secretary of Defense designates a PNT official proactively — before the bill is enacted — or waits for legislative compulsion will signal the department’s seriousness.
- FCC rulemaking: The FCC’s response to the NextNav and NAB petitions, and whether it moves toward a formal rulemaking on GPS backup requirements, will determine whether the civilian economy gets the resilience architecture it needs.
- GPS IIIF and L5 operationalization: With OCX canceled, the timeline for making the L5 civil signal “healthy” (operationally available) is now uncertain. L5 is essential for aviation safety and high-precision applications. Watch for Space Force guidance on the AEP path to L5 operationalization.
Bottom Line
The HASC provision is a meaningful step — but it is a governance fix, not a capability fix. It addresses the accountability deficit that has allowed GPS modernization to drift for over a decade. It does not build a single new satellite, field a single new user terminal, or establish the national resilient PNT architecture that China and Russia already possess. The annual certification requirement is the provision’s sharpest edge: it creates a named official who must go on record about whether the services are funding PNT adequately. That accountability, if enforced, could break the cycle of chronic under-prioritization.
The harder problem — the fragility of GPS signals underpinning virtually every sector of the American economy — remains unaddressed by any funded program. Congress is paying attention. Whether that attention produces durable policy change, or joins the Cruz-Markey Act on the shelf of well-intentioned legislation that was never implemented, will depend on what happens in the weeks and months following June 4.
