The internal structure outlines how each key component integrates and functions together, forming a cohesive system that enables precise and reliable performance.
At close range, Cassiopeia activates its phased-array radar, which electronically steers multiple beams without moving parts. This radar locks onto debris with centimeter-level precision while simultaneously serving as a communication antenna. Advanced beam control and frequency tuning allow the system to track fast-moving objects efficiently and transmit only the most essential data back to Earth.
Once an object’s path is narrowed, Cassiopeia deploys a single-photon LiDAR sensor to precisely measure its distance. By timing individual photons reflected from debris, the LiDAR system dramatically improves accuracy, shrinking large uncertainty regions into precise positional estimates. This step bridges the gap between detection and high-fidelity tracking.
It is designed to continuously survey large regions of Low Earth Orbit. This passive system identifies small debris by detecting faint streaks of reflected sunlight as objects move across the field of view. Onboard processing instantly analyzes these streaks to estimate an object’s initial trajectory, allowing Cassiopeia to detect debris that is currently invisible to traditional ground-based systems.
The satellite is sustainably powered by solar energy. By using monocrystaline bifacial panels, Cassiopeia fully optimizes battery usage by utilising green energy. This mechanism powers all on-board computer systems, electric propulsion, altitude determination and control system and the entire sensor suite.
