Anduril-216 Success: How Private Capital and Infrared Tech are Revolutionizing Space Surveillance
Anduril-216 sensor operations on the dark side of Earth proved that long-wave infrared payloads can track unilluminated orbital objects, Anduril Industries confirmed.
The oven-sized spacecraft orbits at an altitude of approximately 590 kilometers, spending about one-third of every rotation in total darkness. That environment served as the test case for tracking objects when sunlight fails to reflect off them.
SpaceX launched the satellite in July on a shared mission. Anduril funded the flight entirely with private capital rather than a Pentagon contract.
Three technology payloads rode into orbit aboard the spacecraft. Those instruments included an edge-computing processor, an adaptable power management system, and the long-wave infrared sensor.
Tracking the Orbital Shadow
The United States Space Command maintains a network of ground and space-based radar and optical sensors to monitor space traffic. Military commanders rely on that surveillance to detect adversarial satellite maneuvers and issue collision warnings to commercial operators worldwide.
Optical sensors require sunlight reflecting off an object to register its position. Once a satellite enters Earth’s shadow, it drops out of the optical catalog.
Adversarial spacecraft can execute maneuvers inside that window without detection by standard visible-light monitors. Adam Thurn, vice president and general manager of orbital systems at Anduril, explained the operational gap.
“There are no sensors in sovereign territory of the adversaries and, in the period of eclipse, when the surveillance depends on visible sensors, the satellites that are not illuminated by the Sun are simply not seen,” Thurn said.
The long-wave infrared sensor addresses that blind spot. Gokul Subramanian, senior vice president of engineering at Anduril, said that the instrument features a wide dynamic range and low solar exclusion, meaning the Sun rarely blinds it while allowing imaging in complete darkness.
Expanding Orbital Surveillance Networks
The July demonstration follows a corporate acquisition designed to strengthen the company’s space architecture. Anduril announced the purchase of ExoAnalytic Solutions in March, adding a network of 400 global telescopes that track objects in high orbits and convert raw observations into situational awareness tools.
ExoAnalytic was founded in 2008 to adapt missile defense sensor technology for orbital tracking, securing $26 million in SBIR grants starting in 2010. The acquisition added roughly 130 defense space personnel to Anduril’s existing team of about 120 employees in that sector.
Venture capital in defense technology more than doubled in the first half of 2026, surpassing $12 billion compared to nearly $10 billion raised across the entirety of 2025. Anduril itself secured $5 billion in May 2026 at a valuation of $61 billion, following a Series G round in June 2025 that valued the firm at $30.5 billion.
