How sovereign is Europe's space industry? Jul 26, 2026

Show notes

As space becomes an increasingly important part of global communications, national security, and critical infrastructure, European governments are confronting a difficulty: How much control do they need over their own space capabilities?

In this week’s episode, host Maria Varmazis sits down with producer Ethan Cook⁠⁠⁠ to examine the growing push for European space sovereignty and the challenges standing in the way. The conversation explores how supply-chain dependencies can undermine national and regional independence, even when satellites and launch systems are built domestically. Additionally, the two also discuss the trade-offs between complete self-sufficiency and maintaining resilient, diversified international partnerships.

Navigating the GPS threat landscape, with Brandon Karpf. Jun 21, 2026

Show notes

Traditionally, GPS jamming attacks have been confined to the ground; however, new data shows that these attacks could be moving to target signals before they even reach the ground.

In this week’s episode, host Maria Varmazis sits down with Dave Bittner and Brandon Karpf to discuss recent research that suggests the attack landscape for GPS attacks is expanding. If this research is accurate, these attacks represent a significant evolution for how defenders think about this critical technology.

Spoofing ships, jamming drones: how GPS manipulation confuses and compromises. Jun 07, 2026

Show notes

GPS constellations have become foundational in modern society supporting everything from navigation to financial services, making the impacts of GPS disruptions all the more concerning.

As reliance on these systems have grown, so too have efforts by threat actors to disrupt them through techniques such as jamming and spoofing. As these attacks have become more effective, they are becoming increasingly common, especially in conflict zones where disruption and confusion can prove exceedingly valuable.

GPS: A backbone for critical infrastructure. May 31, 2026

Show notes

Since its original creation in the 1970s, GPS has evolved from a technology primarily used by the military to a foundation for modern society.

After the removal of selective availability for civilians in 2000, GPS’s value has significantly expanded. In the past two decades, nearly every critical infrastructure sector–telecommunications, transportation, energy, agriculture, emergency services, and financial services–relies on GPS constellations to ensure that timing and location accuracy are precise. Though many do not see its utility in day-to-day efforts, GPS has become entrenched in modern networks and services. Key sources:
