In this week’s episode, host Maria Varmazis sits down with Doug Anderson, Partner at PwC, and Steve Jordan-Tomaszewski, Vice President of the Space Systems Division at AIA, to dive into PwC’s recent study looki...

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 a...

For years, space cybersecurity has been a long sought after goal, but due to operational constraints, it was largely unfeasible. In this week’s episode, host Maria Varmazis sits down with journalist Shaun Waterman to discuss his recent article “The Newest Space Race is Cyber.” As space has increasingly become a critical infrastructure component, industry leaders and security agencies alike have be...

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 increasi...

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...

Despite being an indispensable technology, traditional GPS remains vulnerable to exploitation and is needed for an update. In this week's episode, host Maria Varmazis sits down with Dr. Sean Gorman, CEO of Zephr.xyz, to discuss the current state of GPS. For decades, GPS has been a cornerstone technology for private, public, and military entities; however, through new technological advancements, co...

For years, in-space internet capabilities were rarely worth the hassle. Now, that’s changing. In today’s episode, Maria Varmazis and Ethan Cook sit down to discuss how internet data moves through space systems and its recent advancements. For decades, GEO satellites made up most of the marketplace; however, LEO satellites are changing the landscape improving connectivity and speeds. Key sources: I...

Please enjoy this encore while the team is out on vacation. When satellites burn up upon re-entering Earth’s atmosphere, they release particles and gases, including metals like aluminium, which may affect atmospheric chemistry. This process, known as atmospheric ablation, is still poorly understood, but early evidence suggests metal content in the atmosphere is rising. To address these uncertainti...
