Mobile Passive Optical Observatories
CONST is a technology and service development activity funded by the European Space Agency under its Space Safety Programme (S2P). The project, led by Sybilla Technologies, focuses on delivering fast, secure, and high-accuracy optical observations of Earth-orbiting objects across LEO, MEO, and GEO regimes using mobile robotic optical ground stations.
These stations, equipped with calibrated sensors and secure data pipelines, enable near real-time detection and tracking of objects in space, supporting rapid situational awareness following major events such as satellite breakups or orbit shifts.
Research & Development: Access to high-precision, calibrated data for object tracking experiments


The CONST system is currently in the beta operational phase. Demonstrations with ESA users are ongoing. Estimated lead time for initial service deployment: → 4–6 months from agreement, depending on site and interface integration.
