GPS/GNSS Policy Recommendations
The RNT Foundation advocates for policies and systems that protect GPS/GNSS satellites, signals, and users.
Our recommendations are organized around three priorities:
-
Protecting signals from interference
-
Toughening receivers against disruption
-
Augmenting GPS/GNSS with complementary terrestrial systems.
Taken together, they form a practical roadmap for building the resilient PNT infrastructure the world needs.
Our Policy Recommendations*
PROTECT the frequencies by preventing interference
- Establish a national capability to detect & rapidly locate jamming.
- Make anti-jamming and anti-spoofing laws enforceable at all levels of government.
- Ensure enough enforcement personnel to detect, prevent, respond to and prosecute jamming.
- Modernize the Communications Act of 1934 to better enable enforcement of sanctions against intentional interference, jamming/spoofing.
- Ensure authorized transmissions in adjacent frequency bands do not exceed highest power provided for by industry standards.
TOUGHEN receivers with readily available technology
- Use receivers and antennas capable of resisting jamming, spoofing, adjacent band interference, other disruptions in critical infrastructure and applications.
- Establish as a requirement or industry best practice having more than one source of precise Position, Navigation and Timing (PNT) for critical infrastructure.
- For critical infrastructure that uses space-based PNT, establish as a requirement or an industry best practice being able to continue normal operations in the event of an extended GPS/GNSS service disruption.
AUGMENT services with difficult to disrupt terrestrial signals
- Encourage development of numerous, complementary terrestrial PNT services to increase resilience (integrated radar, local positioning systems, inertial, etc.)
- Nations establish sovereign core PNT architectures that include terrestrial broadcast and fiber-based time to work with PNT signals from space.**
- Ensure broad adoption of augmenting and alternative systems to protect national and economic security and “take the bullseye off GPS.

What We Believe
These recommendations are grounded in our core beliefs about the state of PNT today — the vulnerabilities, the solutions, and the role government must play.

Presidential Advisory Board Recommendations
The RNT Foundation endorses the recommendations of the President’s National PNT Advisory Board, whose charter expired in March 2025.
* Thanks to Dr. Brad Parkinson and the National PNT Advisory Board for their inspiration and leadership that lead to development of these recommendations.
** The January 2021 US DOT report called for an architecture that included signals from space, fiber, and terrestrial broadcast.
