Global Navigation Satellite Systems Engineering, Policy, and Design
The House Armed Services Committee’s chairman’s mark of the fiscal year 2027 National Defense Authorization Act, released May 26, includes a provision that would establish a designated Pentagon official to oversee the Defense Department’s positioning, navigation and timing enterprise — including alternative PNT programs alongside the existing GPS architecture.

In 2017, the main message at the Munich Satellite Summit was clear: GNSS needs a backup. Nearly 10 years later, the message hasn’t changed; we may have more tools available but very little progress has been made—while the threat to GNSS only continues to grow.

GNSS interference is no longer a distant concern or a technical edge case. As jamming, spoofing and autonomy requirements expose the limits of today’s PNT architectures, LEO is emerging as one of the most important alternatives to understand.

Over the next six issues, Dr. Güenter W. Hein will critically review the development of Galileo, drawing on more than two decades of direct experience with Europe’s satellite navigation system. But this series is not simply a look back. Galileo’s history is also a study in geopolitics, technical ambition, institutional complexity, international cooperation, spectrum management and interoperability—issues that remain central to today’s global PNT aspirations.
