Collision risk estimation
Definition of collision risk estimation
Collision risk estimation is a process involving the evaluation and prediction of the likelihood that two or more orbital objects, such as satellites or space debris, will collide. This analytical capability is essential for maintaining the safety and sustainability of objects in orbit. It involves the use of various data sources, including radar and sensor information, to track and assess the trajectories of these objects.
The goal is to detect potential collision events and provide timely alerts and analysis to operators, enabling them to make informed decisions about maneuvering satellites to avoid collisions. This capability integrates complex mathematical models, computational algorithms, and statistical methods to estimate and mitigate potential collision risks, thereby supporting space traffic management and helping to prevent costly or hazardous space events.
Why collision risk estimation matters for satellite operations
Collision risk estimation underpins day to day satellite operations by turning tracking data into a quantified probability of conjunction and a decision timeline. It directly impacts mission continuity and fuel planning by helping operators prioritize which events to investigate, when to coordinate with other actors, and whether to maneuver given uncertainty, constraints, and safety margins.
At scale for constellations, reliable risk estimation supports sustainable traffic management by reducing false alarms, avoiding unnecessary maneuvers, and limiting the creation of additional debris.
Look Up’s approach: radar tracking and synapse-based risk estimation
Look Up detects and tracks objects in LEO with its SORASYS radar network and fuses those measurements with external data in the SYNAPSE platform to build a timely, coherent space picture for collision risk estimation.
- SYNAPSE predicts collision avoidance with a 99.9% accuracy rate
- Issues alerts within seconds to minutes for high interest events
- Supports operators with tailored maneuver recommendations aligned with mission constraints
These capabilities help operators protect fleets and coordinate responses with reduced uncertainty and faster decision cycles.
We deliver space situational awareness (SSA) and space domain awareness (SDA) solutions that help secure active satellites and ensure safe operations in the ever-growing expanse of space.
