# OrbitTrajectory

`OrbitTrajectory` is a specialized trajectory container for orbital mechanics that stores states in a specific reference frame (ECI or ECEF) and can automatically transform between frames when querying.

OrbitTrajectory has the same API as [Trajectory](trajectory.md), plus frame awareness.
