The global coordinate system is an
inertial coordinate system OXYZ and is connected with the earth.
If the rotation of the Earth is neglected, the ENU reference coordinate system can be considered as an
inertial coordinate system.
In Figure 2, the definition of the coordinate system is as follows: the global
inertial coordinate system [summation]0 is established and called the logical axis coordinate, the local coordinate system of vibration isolator [summation]V is described as the physical axis coordinate, and [summation]C is the centroid
inertial coordinate system.
EquationAre pe components of pe spacecraft velocity vector defined in pe Earp Centered
Inertial Coordinate System.
We denote the fixed
inertial coordinate system as [x.sub.2][y.sub.2][z.sub.2] and the moving noninertial frame of reference as [x.sub.1][y.sub.1][z.sub.1], which is rigidly bounded with the crane boom B[O.sub.2].
For the phases where the foot is moving, we assume a prediction of the position coordinates in the
inertial coordinate system, following constant acceleration motion between samples for the position, circular motion for heading, and constant bias models.
(iv) The origin of the
inertial coordinate system is in the same position as the geometric center and the centroid of the quadrotor.
* The wheel velocity in direction of the wheel axis with regard to the
inertial coordinate system must have zero value.
"The
inertial coordinate system would be the escape system," Moller explains.
As shown in Figure 2, the reachable operating space of the manipulator for extracting ORU in the
inertial coordinate system is
But the star sensor can only output attitude angle of aircraft relative to the
inertial coordinate system for aircraft control system.
