HawkEye 360, the global leader in signals intelligence data and analytics, is proud to announce that a model of its original Pathfinder satellite is now featured in the Smithsonian's National Air and Space Museum on the National Mall within the newly opened RTX Living in the Space Age Hall. The exhibition recognizes the HawkEye 360 Pathfinder as the first satellite to locate and capture a wide range of radio signals. Pathfinder is presented alongside historic U.S. government systems that helped change the face of modern signals intelligence.
"RTX Living in the Space Age" explores the space technologies and infrastructure that quietly support daily life. The exhibition examines the development of systems for Earth observation, communication, and navigation. Within the gallery's section on signals intelligence from space, the HawkEye 360's Pathfinder model represents the emergence and impact of defense tech innovation. Launched in December 2018 and operating in a three-satellite formation about 500 kilometers above Earth, Pathfinder demonstrated a new approach to space-based insights and validated the concept of geolocating and characterizing RF activity as a service. This mission became the foundation for HawkEye 360's operational constellation, which has since expanded to more than thirty satellites delivering global domain awareness.
Originally designed for a two-year demonstration, the Pathfinder cluster exceeded expectations and continued providing valuable data for more than six years. The satellites were formally decommissioned at the end of 2024, concluding a mission that opened the door for a wider variety of US and international government end users to access space-based signals intelligence.
"HawkEye 360 is honored that Pathfinder is represented in this new exhibit, which highlights the technologies shaping the modern space age," said John Serafini, Chief Executive Officer of HawkEye 360. "Pathfinder was the first mission to introduce a space-based signals intelligence service model, and it proved that industry could deliver trusted, operationally relevant defense and national security insights at global scale. That pioneering step continues to drive innovation across our constellation and reinforce the decision advantage we provide to governments and partners worldwide."
HawkEye 360 is proud to contribute to the story of innovation that has defined the past fifty years of space exploration and will continue shaping the decades ahead.
