Acceleration |
Real Number |
The non-rotating coordinate system coincident with
the Fixed system evaluated at the object's coordinate reference
epoch. |
| radial |
Acceleration |
Real Number |
The radial component of the acceleration
vector. |
| in-track |
Acceleration |
Real Number |
The in-track component of the velocity vector
(i.e., the component in the orbit plane perpendicular to the
radial). |
| cross-track |
Acceleration |
Real Number |
The cross-track component of the acceleration
vector (i.e., the component perpendicular to the orbit plane). |
| tangential |
Acceleration |
Real Number |
The component of the acceleration vector along the
velocity direction. |
| normal |
Acceleration |
Real Number |
The normal component of the acceleration vector
(i.e., the component in the orbit plane perpendicular to the
velocity). |
| excess radial |
Acceleration |
Real Number |
The component of the acceleration vector in the
radial direction minus the two-body acceleration |
