Spoofing ships, jamming drones: how GPS manipulation confuses and compromises.
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.
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.
The current state of GPS following OCX with Dr. Sean Gorman, CEO of Zephr.xyz.
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, companies and governments are looking to modernize this technology.
From cyberspace to space-cyber.
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.
