| Name | Description |
|---|---|
| ECIVVLH | Earth centered inertial vehicle velocity local horizontal frame. This frame has the Z axis aligned with the anti-radial direction and the X axis constrained toward the inertial velocity direction. This frame is not restricted to Earth oriented vehicles despite its name. |
| ECFVVLH | Earth centered fixed vehicle velocity local horizontal frame. This frame has the Z axis aligned with the anti-radial direction and the X axis constrained toward the central body fixed velocity direction. This frame is not restricted to Earth oriented vehicles despite its name. |
| BodyFixed | Body fixed frame. This frame moves with the vehicle attitude. |
| LH | Local horizontal frame. This frame has the Z axis aligned with the inward surface normal direction (minus Z is up) and the X axis constrained toward the local north direction. |
