Conjunction screening
Conjunction screening: definition
Conjunction screening refers to the process of assessing the potential for two or more orbital objects to come into proximity with each other, posing a risk of collision in space. This process is critical for Space Situational Awareness (SSA) and involves analyzing the predicted trajectories of these objects to determine the probability of close approaches or conjunctions.
By identifying possible conjunctions, organizations can assess collision risks and take preventative measures, such as altering the trajectory of satellites, to ensure the safety and sustainability of space operations. Conjunction screening uses data from various sensors, including radar and other tracking systems, to provide high-accuracy orbital predictions and alerts for operational decision-making and safeguarding against potential threats in space.
Why conjunction screening matters for safe operations
Conjunction screening is a core operational function for preventing on orbit collisions and maintaining mission continuity. It turns orbit determination and trajectory prediction into time critical decisions by identifying which close approaches are likely to become hazardous, when they will occur, and which asset is at risk, enabling operators to plan and coordinate avoidance actions without unnecessary maneuvers.
At constellation scale, effective screening reduces false alarms, prioritizes events, supports cross operator coordination, and improves space sustainability by limiting fragmentation risk and protecting insured and high value assets.
How Look Up supports conjunction screening
Look Up supports conjunction screening by detecting and tracking objects in LEO with SORASYS radars and by fusing multi source data in the SYNAPSE digital platform to maintain an accurate operational space picture.
SYNAPSE alerts, catalogues, and characterizes objects, then predicts collision risk and supports collision avoidance with tailored maneuver recommendations aligned with mission constraints, including predictions with a 99.9% accuracy rate.
Delivered via API, interface, or on premises deployment, these capabilities help operators act faster, reduce uncertainty, and coordinate safer decisions across fleets.
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.
