Top-level objects
📄️ Operators
An operator is an entity that operates satellites in orbit. Operators in our system may be populated based on users that are submitting ephemerides to the platform, or publicly-available information we have synchronized from other sources.
📄️ Objects
An object represents a satellite in orbit.
📄️ Trajectories
A trajectory is a series of state vectors (position, velocity, time and covariance) related to a single object. Depending on the file format, it may contain other metadata as well.
📄️ CDMs
A Conjunction Data Message (CDM) is a representation of a close approach between two trajectories. (see the CCSDS spec).
📄️ Conjunction Events
A conjunction event represents a time where two objects fall within our screening volume at their time of closest approach (TCA).
