Eyes on orbit: How advanced vision systems are making space safer

Low Earth Orbit (LEO) has become one of the busiest environments beyond our planet. Thousands of active satellites now share space with spent rocket stages, defunct spacecraft, and millions of debris fragments travelling at velocities of several kilometers per second. As commercial constellations continue to grow and in-orbit servicing becomes a reality, ensuring the safety and sustainability of space has never been more important. This is where Space Situational Awareness (SSA) comes into play. By accurately detecting, identifying and tracking objects in orbit, SSA enables operators to prevent collisions, support autonomous missions and extend the lifespan of valuable space assets. But tracking an object in orbit is far more challenging than it may seem.

When the target doesn’t want to be seen

Many orbital objects are uncooperative targets. Unlike satellites designed for rendezvous operations, these objects provide no navigation aids, communication signals, or reference markers. They may be tumbling, partially damaged, or completely inactive.

At the same time, lighting conditions in space are constantly changing. A spacecraft can transition within seconds from deep darkness into direct sunlight, creating extreme contrast that can easily overwhelm conventional imaging systems.

Imagine trying to photograph a small, dark marble flying several kilometers per second while alternating between pitch-black darkness and blinding glare. That is the reality of modern Space Situational Awareness.

To tackle these challenges, optical payloads must integrate high-precision hardware, optimal sensor selection and intelligent on-board processing to deliver exceptional image quality while remaining reliable under some of the harshest environmental conditions imaginable.

Precision optics designed for the realities of space

Successful SSA missions rely on far more than a high-resolution camera. They require a carefully engineered optical payload where every component is optimized for mission performance.

One of the greatest challenges is maintaining image quality despite rapidly changing illumination. During a single orbit, a spacecraft may repeatedly transition between deep darkness and direct sunlight, creating intense glare and high-contrast scenes.

To overcome this, optical payloads should incorporate advanced stray light suppression and anti-glare optical designs that preserve image contrast even when observing targets near the Sun. Crucially, this performance depends on selecting the right wavebands, ranging from high-precision visible (VIS) sensors to Short-Wave Infrared (SWIR) and Medium-Wave Infrared (WMIR), allowing systems to track thermal signatures and detect uncooperative targets when visible light alone isn’t enough.

As missions expand beyond Low Earth Orbit towards GEO and cislunar space, these optical architectures must remain adaptable to different operational environments while maintaining the accuracy required for autonomous navigation and rendezvous.

The edge AI advantage: Intelligence at the payload level

Capturing high-contrast imagery is only half the battle; the real hurdle during proximity operations is time. Spacecraft executing high-speed rendezvous maneuvers cannot afford to wait for ground-station latency to process images and adjust course.

Modern vision systems are moving intelligence directly to the edge. By embedding AI processing on board, the payload can perform real-time target detection, feature identification and trajectory tracking directly inside the spacecraft.

To deliver this capability seamlessly, we collaborate closely with specialized AI processing partners. Integrating their advanced algorithms directly into our space-qualified optical hardware allows us to provide customers with a complete vision product ready for autonomous, real-time orbital decision-making.

From long-range acquisition to close-range operations

These engineering challenges are already impacting today’s in-orbit servicing missions.

One recent contribution to a customer’s mission required an optical payload capable of continuously tracking non-cooperative satellites in LEO from an initial approach distance of 15 kilometers down to just 5 meters before docking, where a LiDAR sensor system takes over for the final proximity operations. Achieving this level of performance demanded a multi-optics architecture able to maintain reliable tracking despite rapidly changing illumination, large variations in target size and stringent accuracy requirements.

This type of capability is becoming progressively important as future missions move beyond observation towards active servicing, inspection and debris removal.

Building the future of safe and sustainable space operations

As Earth’s orbits become increasingly congested, advanced vision systems are evolving into fundamental enablers of safer and more sustainable space operations. Whether supporting debris removal, satellite inspection or autonomous in-orbit servicing, optical payloads must combine precision imaging, intelligent on-board processing and uncompromising reliability.
