Conjunction Data Message exchange
Definition of conjunction data message (CDM) exchange
Conjunction Data Message (CDM) exchange refers to the systematic process of coordinating and sharing data specifically related to conjunction assessments and analyses between space organizations, operators, and stakeholders.
This process involves the communication and transfer of standardized messages containing detailed information about potential close approaches, or conjunctions, between satellites or other orbital objects.
The CDM exchange aims to enhance situational awareness, facilitate informed decision-making, and enable timely actions to mitigate collision risks in space.
It supports the collaborative efforts required for effective space traffic management and contributes to maintaining the safety, security, and sustainability of space operations.
Why CDM exchange matters for collision risk management
Conjunction Data Message exchange is the operational backbone of coordinated collision risk management: it lets operators share a common, standardized view of a close approach and update it as new tracking data arrives.
Reliable exchanges reduce uncertainty, shorten decision cycles for screening and maneuver planning, and improve coordination between satellite operators, service providers, and public authorities, especially when multiple parties may be involved in the same event.
At scale, consistent CDM workflows support safer constellation operations and more sustainable space traffic management by enabling traceable, time-critical decisions.
How Look Up supports cdm-driven operations
Look Up supports Conjunction Data Message-driven operations by detecting and tracking objects with SORASYS radars and by fusing multi-source data in SYNAPSE to produce a timely, consistent space picture.
SYNAPSE helps operators catalogue objects, issue alerts, and predict conjunction risk, including collision avoidance predictions with a 99.9% accuracy rate, delivered via API or interface and deployable on-premises for secure operations.
Together, these capabilities help operators coordinate responses faster and protect fleets through actionable collision warnings and tailored maneuver recommendations.
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.
