Global Navigation Satellite Systems Engineering, Policy, and Design
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.

From IMU fundamentals to low-SWaP-C system design, experts explain how tightly integrated GNSS-INS is delivering resilient navigation when satellite signals are degraded, intermittent or denied.

These misleading narratives are keeping the U.S. from advancing PNT policy, putting everyone who depends on GNSS at risk.

More than 50 years ago, the Department of Defense (DoD) began a PNT project to support deployed forces and “put five bombs in the same hole.” While not part of its original mission, signals from GPS are now accessed by and even more important to civil users.

The PNT industry must adapt to a changing landscape and find a way to provision for continual improvement. Why SDR architectures may be the answer.

Thought leaders recently gathered to discuss the growing threats to GPS, the most pressing challenges the industry faces and the best way forward. Here, we’ve put together a comprehensive view of all the critical issues tackled during the PNT Leadership Summit, a venue where the industry’s brightest minds could bring up their concerns, frustrations and recommend solutions.
