How debris increases collision risk in earth orbit

Debris objects are a primary driver of collision risk in Earth orbit because they are numerous, often uncooperative (no telemetry, no attitude control), and can be difficult to observe, especially when small or recently generated.

Operationally, this translates into higher conjunction volumes, increased uncertainty in orbit determination, and tighter decision timelines for collision avoidance, particularly for constellation operators managing many satellites simultaneously.

Reliable debris tracking and characterization underpins accurate conjunction assessment, reduces false alarms and unnecessary maneuvers, supports post-event analysis after fragmentation, and is essential to long-term space sustainability and responsible traffic coordination.

How Look Up helps operators manage debris-driven risk

Look Up helps operators manage debris-driven risk by detecting and tracking LEO debris with SORASYS, its ground-based radar/sensor network, with detection down to a few cm and centimetric accuracy to improve orbit determination where it matters most.

Through its SYNAPSE digital platform, Look Up fuses its own sensor data with external data to build and maintain a timely space picture, produce object cataloguing and ID cards, and deliver alerts and analytics via API or interface (with on-premises deployment options for secure operations).

• This supports collision avoidance workflows by predicting conjunctions with a 99.9% accuracy rate, issuing timely warnings, and recommending maneuvers aligned with mission constraints, reducing uncertainty, avoiding unnecessary fuel expenditure, and scaling safer operations across fleets and constellations.
