Web12 de abr. de 2024 · This is why defining quaternions to rotate from a GLOBAL frame to a local frame (or vice-versa) is incredibly important. The ENU to NED rotation is a perfect example, where the rotation quaternion is [0; sqrt (2)/2; sqrt (2)/2; 0], a "midpoint" between the two abscissa (X) axes (in both the global and local frames of reference).

WebYou can convert the body-relative velocties to NED-velocities if you know the orientation of the body (roll, pitch and yaw). Let's say you have a drone moving at heading 030°, and the GPS says the forward velocity is 1 m/s, the drone will have the following North velocity: vel_north = 1 m/s * cos (30°) = 0.86 m/s. and the following East velocity:
