- axis (m):
[x, y, z]
- phi (deg): angle on x-y plane. Positive x-axis is 0 deg, positive y-axis is 90 deg
- theta (deg): angle on z-x plane. Positive z-axis is 0 deg, x-y plane is 90 deg
- azimuth (deg): azimuth -90 ~ 90 deg equal to phi -90 ~ 90 deg
- elevation (deg): elevation -90 ~ 90 deg equal to theta 180 ~ 0 deg
- axis (m):
-
- axis (m):
[x, y, z]
- yaw (deg): rotation along z-axis. Positive yaw rotates object from positive x-axis to positive y-axis
- pitch (deg): rotation along y-axis. Positive pitch rotates object from positive x-axis to positive z-axis
- roll (deg): rotation along x-axis. Positive roll rotates object from positive z-axis to negative y-axis
- origin (m):
[x, y, z]
- rotation (deg):
[yaw, pitch, roll]
- rotation (deg/s): rate
[yaw rate, pitch rate, roll rate]
- axis (m):
