Anduril Demonstrates Satellite Sensor for Tracking Maneuvers in Orbital Darkness
New infrared technology enables tracking of spacecraft hidden within Earth's orbital shadow.
1Successful Orbital Technology Demonstration
Anduril Industries successfully demonstrated a new satellite-based sensor designed to track spacecraft during Earth's eclipse periods. The oven-sized satellite, named Anduril-216, launched in July via a SpaceX rideshare mission. It operates at an altitude of 590 kilometers, testing advanced infrared imaging and edge-compute processing capabilities while orbiting in total darkness.
2Addressing Critical Tracking Gaps
Current space traffic monitoring relies heavily on ground-based radars and visible light sensors, which struggle when satellites enter Earth's shadow. This creates a visibility gap, preventing military commanders from detecting potential threatening maneuvers. Anduril's new long-wave infrared sensor aims to eliminate this blind spot by detecting heat signatures from maneuvering spacecraft.
3Advanced Infrared Imaging Capabilities
The sensor utilizes long-wave infrared technology, which features a high dynamic range and low solar exclusion. This allows the system to capture imagery even when the Sun is nearby. Senior vice president Gokul Subramanian noted that the sensor can perform both unresolved and resolved imagery, potentially enabling future close-proximity satellite inspections.
4Integrating Autonomous Weapon Technology
Engineers adapted imaging technology originally developed for Anduril’s autonomous weapons systems for use in the space environment. The satellite features an edge-compute processor that fuses data from multiple sensors to generate tracking solutions autonomously. This reduces the need for constant intervention or data analysis from ground-based control teams during operations.
5Strategic Partnership for Platform Development
Anduril collaborated with satellite-manufacturing startup Apex Space to build the Anduril-216 platform. The company currently has no plans to establish its own internal satellite production line. Instead, Anduril intends to purchase third-party platforms and integrate its proprietary sensor and compute modules to perform a wide variety of specialized space missions.
6Focus on Space Domain Awareness
The primary objective of the mission is to acquire space domain awareness data for sale to the US military. Anduril is currently not offering the system as a merchant supplier for hardware. By focusing on data services, the company aims to maintain custody of objects that were previously difficult to track.
7Future Expansion and Potential Applications
While the current focus remains on optimizing tracking sensors for low-Earth orbit, the technology has broader potential. Anduril executives suggested the system could eventually be deployed in other orbits, including cislunar space near the Moon. This flexibility allows the company to adapt its sensor modules for diverse mission requirements as needs evolve.
8Implications for Global Space Security
The ability to monitor maneuvers during orbital night is essential for both national security and collision avoidance. By closing existing surveillance gaps, Anduril provides the Space Force with better data to assess potential threats. This capability marks a significant shift in how commercial entities contribute to monitoring activity in the increasingly crowded orbital environment.
