The angles encoded in the quaternion are in the global frame (roll: positive is tilt to the right, pitch: positive is tilting up, yaw is turn to the right). This message should be broadcast at a low regular rate (e.g. 10Hz).</description> | ||
| + <description>Message reporting the status of a gimbal device. | ||
| + This message should be broadcast by a gimbal device component at a low regular rate (e.g. 5 Hz). | ||
| + For the angles encoded in the quaternion and the angular velocities holds: | ||
| + If the flag GIMBAL_DEVICE_FLAGS_YAW_IN_VEHICLE_FRAME is set, then they are relative to the vehicle heading (vehicle frame). | ||
| + If the flag GIMBAL_DEVICE_FLAGS_YAW_IN_EARTH_FRAME is set, then they are relative to absolute North (earth frame). | ||
| + If neither of these flags are set, then (for backwards compatibility) it holds: | ||
| + If the flag GIMBAL_DEVICE_FLAGS_YAW_LOCK is set, then they are relative to absolute North (earth frame), | ||
| + else they are relative to the vehicle heading (vehicle frame). | ||
| + Other conditions of the flags are not allowed. | ||
| + The quaternion and angular velocities in the other frame can be calculated from delta_yaw and delta_yaw_velocity as | ||
| + q_earth = q_delta_yaw * q_vehicle and w_earth = w_delta_yaw_velocity + w_vehicle (if not NaN). | ||
| + If neither the GIMBAL_DEVICE_FLAGS_YAW_IN_VEHICLE_FRAME nor the GIMBAL_DEVICE_FLAGS_YAW_IN_EARTH_FRAME flag is set, | ||
| + then (for backwards compatibility) the data in the delta_yaw and delta_yaw_velocity fields are to be ignored. | ||
| + New implementations should always set either GIMBAL_DEVICE_FLAGS_YAW_IN_VEHICLE_FRAME or GIMBAL_DEVICE_FLAGS_YAW_IN_EARTH_FRAME, | ||
| + and always should set delta_yaw and delta_yaw_velocity either to the proper value or NaN.</description> | ||
