Conjunction event
Definition
A conjunction event in the context of space situational awareness refers to a situation where two or more space objects, such as satellites, debris, or other orbital entities, are projected to come into close proximity to each other in orbit. This proximity poses a risk of collision, necessitating careful monitoring and analysis to assess and mitigate potential impact.
Conjunction events are a critical focus in the field of space traffic management, as they involve predicting the likelihood of collisions, evaluating possible risk scenarios, and deciding on maneuvers to reduce or avoid collisions. These events require the integration of data from various sources, such as radars and sensors, to produce high-accuracy orbital information and enable proactive operational decision-making to ensure space safety and sustainability.
Operational impact and collision risk management
Conjunction events drive day-to-day collision risk management in LEO and beyond, forcing operators to decide quickly whether to monitor, coordinate, or maneuver while balancing mission constraints, fuel budgets, and service continuity.
Their handling depends on timely, accurate orbit determination and uncertainty reduction, because small errors in tracking and covariance can materially change the estimated probability of collision and the recommended response.
At scale, frequent conjunctions also increase coordination overhead between operators and raise sustainability stakes, since missed or late actions can create additional debris and degrade the operating environment for all users.
How Look Up supports conjunction event management
Look Up helps operators manage conjunction events by detecting and tracking objects with SORASYS radars and by fusing multi-source data in the SYNAPSE platform to maintain an actionable space picture.
SYNAPSE predicts collision risk with 99.9% accuracy and delivers alerts plus collision avoidance support, including tailored maneuver recommendations aligned with mission constraints.
Via API, interface, or on-premises deployment, Look Up enables faster decisions, reduced uncertainty, and safer fleet and constellation operations.
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.
