Space Conjunction Data Service

    A global standardized CDM data service platform for space conjunction detection, risk analytics

    Conjunction data in this service is generated through a preliminary screening process based on SGP4 (Simplified General Perturbations Model 4) orbit propagation. Space object ephemerides are propagated using publicly available orbital elements to identify potential close-approach events and produce candidate Conjunction Data Messages (CDMs).
    This dataset is provided as a rapid screening product for preliminary conjunction assessment, supporting early detection and prioritization of potential close-approach events. It serves as upstream input for high-precision orbit determination (OD), covariance analysis, and refined collision probability (Pc) evaluation.
