Satcat

Satcat provides open access to foundational space object data and verified business listings. It supports transparency, public situational awareness, and promotes educational use. The public-facing tier offers limited, read-only access to selected elements of the broader Satcat platform.

Additional tools and data views are available with a free account.

warning

Satcat's public facing data is not intended for operational decision-making. Data is derived from open sources, often at coarse fidelity, and is not augmented with operator ephemeris or telemetry. All public-facing tools are intended for informational and educational use only.

For custody tracking, high-accuracy ephemerides, advanced conjunction assessment and alerting, and operator-to-operator coordination, see Satcat Operations.
