Formation components are a subset of Calculation Object components. They set relative values for use in formation flying.

The Formation components are:
| Component | Description |
|---|---|
| CloseApproachBearing | Angle from relative velocity vector to reference |
| CloseApproachMagnitude | Magnitude of close approach vector on close approach plane |
| CloseApproachTheta | Angle from X to close approach vector on close approach plane |
| CloseApproachX | X component of close approach vector on close approach plane |
| CloseApproachY | Y component of close approach vector on close approach plane |
| CosineOfCloseApproachBearing | Cosine of Angle from relative velocity vector to reference |
| RelGroundTrackError | Relative Ground track error compared to the reference satellite |
| Rel Mean Arg of Lat | Relative mean argument of latitude compared to the master satellite |
| Rel Mean Arg of Perigree | Relative mean argument of perigee compared to the master satellite |
| Rel Mean Eccentricity | Relative mean eccentricity compared to the master satellite |
| Rel Mean Inclination | Relative mean inclination compared to the master satellite |
| Rel Mean Mean Anomaly | Relative mean mean anomaly compared to the master satellite |
| Rel Mean Period | Relative mean orbit period compared to the master satellite |
| Rel Mean RAAN | Relative mean RAAN compared to the master satellite |
| Rel Mean Semimajor Axis | Relative mean semimajor axis compared to the master satellite |
| RelativeAtAOL | Relative value of a specified function compared to the master satellite at the same argument of latitude |
| RelativeValue | Relative value of a specified function compared to the reference satellite |
The attributes for each component have the same names and value selections that appear in the Astrogator user interface.
