EstimatedState class abstract
Estimated State class
This message presents the estimated state of the vehicle.
EstimatedState is a complete description of the system in terms of parameters such as position, orientation and velocities at a particular moment in time.
The system position is given by a North-East-Down (NED) local tangent plane displacement (x, y, z) relative to an absolute WGS-84 coordinate (latitude, longitude, height above ellipsoid).
The symbols for position and attitude as well as linear and angular velocities were chosen according to SNAME's notation (1950). The body-fixed reference frame and Euler angles are depicted next:
