The Relative Motion components are:
| Component | Description |
|---|---|
| CrossTrack | Relative Cross-Track value compared to reference satellite |
| CrossTrackRate | Relative Cross-Track Rate value compared to reference satellite |
| InTrack | Relative In-Track value compared to reference satellite |
| InTrackRate | Relative In-Track Rate value compared to reference satellite |
| Normal | Relative Normal value compared to reference satellite |
| NormalRate | Relative Normal Rate value compared to reference satellite |
| RICAzimuth | Angle measured in the plane formed by the In-Track and Cross-Track directions, positive from the In-Track direction toward the Cross-Track direction |
| RICAzimuthRate | Rate of change of the RIC azimuth |
| RICElevation | Angle measured perpendicular to the plane formed by the In-Track and Cross-Track directions, positive toward the Radial direction |
| RICElevationRate | Rate of change of the RIC elevation |
| Radial | Relative Radial value compared to reference satellite |
| RadialRate | Relative Radial Rate value compared to reference satellite |
| Range | Relative Range value compared to reference satellite |
| RangeRate | Relative Range Rate value compared to reference satellite |
| Tangential | Relative Tangential value compared to reference satellite |
| TangentialRate | Relative Tangential Rate value compared to reference satellite |
| TimeDifference | Relative Time-Difference value compared to reference satellite |
The attributes for each component have the same names and value selections that appear in the Astrogator graphical user interface.
