When ICEYE needed a reliable way to verify the accuracy of their satellite radar measurements, they partnered with GNO SYS to build the ground reference points that would make it possible. Our team designed and installed custom corner reflectors that give ICEYE a clear and consistent signal to compare against what their satellites see from orbit.
These reflectors act as bright, dependable targets in SAR imagery, helping ICEYE confirm that their satellites can detect very small movements on the ground with millimetre level precision. This level of accuracy is important for monitoring infrastructure, tracking environmental change, and supporting disaster response.
To make this work, we created reflectors that produce strong radar returns, installed them on stable foundations, and engineered a simple but precise height adjustment system. With twenty turns of a hand crank, the reflector moves exactly one millimetre. ICEYE can then re image the site and confirm that the change is detected.
The results were clear. ICEYE validated that their satellites can measure small vertical shifts with impressive accuracy. This strengthens confidence in the data their satellites deliver to governments, emergency managers, and industry partners.
At GNO SYS, we take pride in supporting innovation while protecting our clients’ intellectual property. ICEYE retained full ownership of the reflector design, and we helped ensure their engineering insights are protected for future missions.
What This Means for Operators and Analysts
- Trusted validation for displacement products that inform safety and maintenance.
- Repeatable field methods that scale across sites and seasons.
- Lower risk deployment due to stable mounts and calibrated adjustment.
- Faster iteration between space segment, models, and ground truth.
The GNO‑SYS and ICEYE collaboration shows how thoughtful engineering and precise fieldwork can enhance the performance of space based remote sensing. By combining rigorous design, practical deployment, and millimetre scale control, we delivered a tailored solution that strengthens confidence in satellite derived measurements.
This project reflects how GNO‑SYS works with clients to design, develop, deploy, and discover. The result is technology that performs in the field and insight that leaders can trust.
